Introduction

Popup Dialog is a simple, customizable popup dialog written in Swift.

Features

  • Easy to use API with hardly any boilerplate code
  • Convenient default view with image, title, message
  • Supports custom view controllers
  • Slick transition animations
  • Fully themeable via appearance, including fonts, colors, corner radius, shadow, overlay color and blur, etc.
  • Can be dismissed via swipe and background tap
  • Objective-C compatible
  • Works on all screens and devices supporting iOS 10.0+

 

Installation

This version is Swift 5 compatible. For the Swift 4.2 version, please use V1.0.0.

CocoaPods

PopupDialog is available through CocoaPods. Simply add the following to your Podfile:

use_frameworks!

target '<Your Target Name>'
pod 'PopupDialog', '~> 1.1'

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. A minimum version of 0.17 is required.

To install, simply add the following lines to your Cartfile:

github "Orderella/PopupDialog" ~> 1.1

Manually

If you prefer not to use either of the above mentioned dependency managers, you can integrate PopupDialog into your project manually by adding the files contained in the Classes folder to your project. Moreover, you have to manually add the classes of DynamicBlurView to your project.

 

Example

You can find this and more example projects in the repo. To run it, clone the repo, and run pod install from the Example directory first.

import PopupDialog

// Prepare the popup assets
let title = "THIS IS THE DIALOG TITLE"
let message = "This is the message section of the popup dialog default view"
let image = UIImage(named: "pexels-photo-103290")

// Create the dialog
let popup = PopupDialog(title: title, message: message, image: image)

// Create buttons
let buttonOne = CancelButton(title: "CANCEL") {
    print("You canceled the car dialog.")
}

// This button will not the dismiss the dialog
let buttonTwo = DefaultButton(title: "ADMIRE CAR", dismissOnTap: false) {
    print("What a beauty!")
}

let buttonThree = DefaultButton(title: "BUY CAR", height: 60) {
    print("Ah, maybe next time :)")
}

// Add buttons to dialog
// Alternatively, you can use popup.addButton(buttonOne)
// to add a single button
popup.addButtons([buttonOne, buttonTwo, buttonThree])

// Present dialog
self.present(popup, animated: true, completion: nil)

 

Usage

PopupDialog is a subclass of UIViewController and as such can be added to your view controller modally. You can initialize it either with the handy default view or a custom view controller.

Default Dialog

public convenience init(
    title: String?,
    message: String?,
    image: UIImage? = nil,
    buttonAlignment: UILayoutConstraintAxis = .vertical,
    transitionStyle: PopupDialogTransitionStyle = .bounceUp,
    preferredWidth: CGFloat = 340,
    tapGestureDismissal: Bool = true,
    panGestureDismissal: Bool = true,
    hideStatusBar: Bool = false,
    completion: (() -> Void)? = nil) 

The default dialog initializer is a convenient way of creating a popup with image, title and message (see image one and three).

Bascially, all parameters are optional, although this makes no sense at all. You want to at least add a message and a single button, otherwise the dialog can't be dismissed, unless you do it manually.

If you provide an image it will be pinned to the top/left/right of the dialog. The ratio of the image will be used to set the height of the image view, so no distortion will occur.

Custom View Controller

public init(
    viewController: UIViewController,
    buttonAlignment: UILayoutConstraintAxis = .vertical,
    transitionStyle: PopupDialogTransitionStyle = .bounceUp,
    preferredWidth: CGFloat = 340,
    tapGestureDismissal: Bool = true,
    panGestureDismissal: Bool = true,
    hideStatusBar: Bool = false,
    completion: (() -> Void)? = nil) 

You can pass your own view controller to PopupDialog (see image two). It is accessible via the viewController property of PopupDialog, which has to be casted to your view controllers class to access its properties. Make sure the custom view defines all constraints needed, so you don't run into any autolayout issues.

Buttons are added below the controllers view, however, these buttons are optional. If you decide to not add any buttons, you have to take care of dismissing the dialog manually. Being a subclass of view controller, this can be easily done via dismissViewControllerAnimated(flag: Bool, completion: (() -> Void)?).

Button Alignment

Buttons can be distributed either .horizontal or .vertical, with the latter being the default. Please note distributing buttons horizontally might not be a good idea if you have more than two buttons.

public enum UILayoutConstraintAxis : Int {
	case horizontal
	case vertical
}

Transition Style

You can set a transition animation style with .bounceUp being the default. The following transition styles are available

public enum PopupDialogTransitionStyle: Int {
    case bounceUp
    case bounceDown
    case zoomIn
    case fadeIn
}

Preferred Width

PopupDialog will always try to have a max width of 340 . On iPhones with smaller screens, like iPhone 5 SE, width would be 320. 340 is also the standard width for iPads. By setting preferredWidth you can override the max width of 340 for iPads only.

Gesture Dismissal

Gesture dismissal allows your dialog being dismissed either by a background tap or by swiping the dialog down. By default, this is set to true. You can prevent this behavior by setting either tapGestureDismissal or panGestureDismissal to false in the initializer.

Hide Status Bar

PopupDialog can hide the status bar whenever it is displayed. Defaults to false. Make sure to add UIViewControllerBasedStatusBarAppearance to Info.plist and set it to YES.

Completion

This completion handler is called when the dialog was dismissed. This is especially useful for catching a gesture dismissal.

 

Default Dialog Properties

If you are using the default dialog, you can change selected properties at runtime:

// Create the dialog
let popup = PopupDialog(title: title, message: message, image: image)

// Present dialog
self.present(popup, animated: true, completion: nil)

// Get the default view controller and cast it
// Unfortunately, casting is necessary to support Objective-C
let vc = popup.viewController as! PopupDialogDefaultViewController

// Set dialog properties
vc.image = UIImage(...)
vc.titleText = "..."
vc.messageText = "..."
vc.buttonAlignment = .horizontal
vc.transitionStyle = .bounceUp

 

Styling PopupDialog

Appearance is the preferred way of customizing the style of PopupDialog. The idea of PopupDialog is to define a theme in a single place, without having to provide style settings with every single instantiation. This way, creating a PopupDialog requires only minimal code to be written and no "wrappers".

This makes even more sense, as popup dialogs and alerts are supposed to look consistent throughout the app, that is, maintain a single style.

Dialog Default View Appearance Settings

If you are using the default popup view, the following appearance settings are available:

let dialogAppearance = PopupDialogDefaultView.appearance()

dialogAppearance.backgroundColor      = .white
dialogAppearance.titleFont            = .boldSystemFont(ofSize: 14)
dialogAppearance.titleColor           = UIColor(white: 0.4, alpha: 1)
dialogAppearance.titleTextAlignment   = .center
dialogAppearance.messageFont          = .systemFont(ofSize: 14)
dialogAppearance.messageColor         = UIColor(white: 0.6, alpha: 1)
dialogAppearance.messageTextAlignment = .center

Dialog Container Appearance Settings

The container view contains the PopupDialogDefaultView or your custom view controller. the following appearance settings are available:

let containerAppearance = PopupDialogContainerView.appearance()

containerAppearance.backgroundColor = UIColor(red:0.23, green:0.23, blue:0.27, alpha:1.00)
containerAppearance.cornerRadius    = 2
containerAppearance.shadowEnabled   = true
containerAppearance.shadowColor     = .black
containerAppearance.shadowOpacity   = 0.6
containerAppearance.shadowRadius    = 20
containerAppearance.shadowOffset    = CGSize(width: 0, height: 8)
containerAppearance.shadowPath      = CGPath(...)

Overlay View Appearance Settings

This refers to the view that is used as an overlay above the underlying view controller but below the popup dialog view. If that makes sense ;)

let overlayAppearance = PopupDialogOverlayView.appearance()

overlayAppearance.color           = .black
overlayAppearance.blurRadius      = 20
overlayAppearance.blurEnabled     = true
overlayAppearance.liveBlurEnabled = false
overlayAppearance.opacity         = 0.7

Note

Setting liveBlurEnabled to true, that is enabling realtime updates of the background view, results in a significantly higher CPU usage /power consumption and is therefore turned off by default. Choose wisely whether you need this feature or not ;)

Button Appearance Settings

The standard button classes available are DefaultButton, CancelButton and DestructiveButton. All buttons feature the same appearance settings and can be styled separately.

var buttonAppearance = DefaultButton.appearance()

// Default button
buttonAppearance.titleFont      = .systemFont(ofSize: 14)
buttonAppearance.titleColor     = UIColor(red: 0.25, green: 0.53, blue: 0.91, alpha: 1)
buttonAppearance.buttonColor    = .clear
buttonAppearance.separatorColor = UIColor(white: 0.9, alpha: 1)

// Below, only the differences are highlighted

// Cancel button
CancelButton.appearance().titleColor = .lightGray

// Destructive button
DestructiveButton.appearance().titleColor = .red

Moreover, you can create a custom button by subclassing PopupDialogButton. The following example creates a solid blue button, featuring a bold white title font. Separators are invisible.

public final class SolidBlueButton: PopupDialogButton {

    override public func setupView() {
        defaultFont           = .boldSystemFont(ofSize: 16)
        defaultTitleColor     = .white
        defaultButtonColor    = .blue
        defaultSeparatorColor = .clear
        super.setupView()
    }
}

These buttons can be customized with the appearance settings given above as well.

 

Dark mode example

The following is an example of a Dark Mode theme. You can find this in the Example project AppDelegate, just uncomment it to apply the custom appearance.

// Customize dialog appearance
let pv = PopupDialogDefaultView.appearance()
pv.titleFont    = UIFont(name: "HelveticaNeue-Light", size: 16)!
pv.titleColor   = .white
pv.messageFont  = UIFont(name: "HelveticaNeue", size: 14)!
pv.messageColor = UIColor(white: 0.8, alpha: 1)

// Customize the container view appearance
let pcv = PopupDialogContainerView.appearance()
pcv.backgroundColor = UIColor(red:0.23, green:0.23, blue:0.27, alpha:1.00)
pcv.cornerRadius    = 2
pcv.shadowEnabled   = true
pcv.shadowColor     = .black

// Customize overlay appearance
let ov = PopupDialogOverlayView.appearance()
ov.blurEnabled     = true
ov.blurRadius      = 30
ov.liveBlurEnabled = true
ov.opacity         = 0.7
ov.color           = .black

// Customize default button appearance
let db = DefaultButton.appearance()
db.titleFont      = UIFont(name: "HelveticaNeue-Medium", size: 14)!
db.titleColor     = .white
db.buttonColor    = UIColor(red:0.25, green:0.25, blue:0.29, alpha:1.00)
db.separatorColor = UIColor(red:0.20, green:0.20, blue:0.25, alpha:1.00)

// Customize cancel button appearance
let cb = CancelButton.appearance()
cb.titleFont      = UIFont(name: "HelveticaNeue-Medium", size: 14)!
cb.titleColor     = UIColor(white: 0.6, alpha: 1)
cb.buttonColor    = UIColor(red:0.25, green:0.25, blue:0.29, alpha:1.00)
cb.separatorColor = UIColor(red:0.20, green:0.20, blue:0.25, alpha:1.00)

I can see that there is room for more customization options. I might add more of them over time.

 

Screen sizes and rotation

Rotation and all screen sizes are supported. However, the dialog will never exceed a width of 340 points on iPhones. For iPads, you can set preferredWidth when initializing a new PopupDialog. However, landscape mode will not work well if the height of the dialog exceeds the width of the screen.

 

Working with text fields

If you are using text fields in your custom view controller, popup dialog makes sure that the dialog is positioned above the keyboard whenever it appears. You can opt out of this behaviour by setting keyboardShiftsView to false on a PopupDialog.

Testing

PopupDialog exposes a nice and handy method that lets you trigger a button tap programmatically:

public func tapButtonWithIndex(_ index: Int)

Other than that, PopupDialog unit tests are included in the root folder.

 

Objective-C

PopupDialog can be used in Objective-C projects as well. Here is a basic example:

PopupDialog *popup = [[PopupDialog alloc] initWithTitle: @"Title"
                                                message: @"This is a message"
                                                  image: nil
                                        buttonAlignment: UILayoutConstraintAxisVertical
                                        transitionStyle: PopupDialogTransitionStyleBounceUp
                                         preferredWidth: 380
                                    tapGestureDismissal: NO
                                    panGestureDismissal: NO
                                          hideStatusBar: NO
                                             completion: nil];

DestructiveButton *delete = [[DestructiveButton alloc] initWithTitle: @"Delete"
                                                              height: 45
                                                        dismissOnTap: YES
                                                              action: nil];

CancelButton *cancel = [[CancelButton alloc] initWithTitle: @"Cancel"
                                                    height: 45
                                              dismissOnTap: YES
                                                    action: nil];

DefaultButton *ok = [[DefaultButton alloc] initWithTitle: @"OK"
                                                  height: 45
                                            dismissOnTap: YES
                                                  action: nil];

[dialog addButtons:@[delete, cancel, ok]];

[self presentViewController:popup animated:YES completion:nil];

 

Bonus

Shake animation

If you happen to use PopupDialog to validate text input, for example, you can call the handy shake() method on PopupDialog.

    Custom popupDialog breaks when VC is presented above it

    @mwfire I copied the custom xib from the example and place it in my project. I removed all the stuff in it and replaced it with a tableView displaying my contact list. It works perfectly at this point. When a cell accessory is tapped, I present the MFMessageComposeViewController. When that gets dismissed, my popup dialogue completely breaks. Here are the photos in action sequence.

    What could it be?😂

    Hi I was wondering if it is possible to pass information to the PopupViewController which can then be used in labels. I have three buttons in a view controller that all launch the same PopupViewController, but I want them to display different information in the labels etc. based on what button was selected, but I cannot seem to find a way to do this! e.g. if button 1 is selected, the label displays 'Button 1 was selected', if button 2 was selected then the label displays 'Button 2 was selected' etc.

    What did you do?

    I tried fiddling with button.contentHorizontalAlignment and button.contentEdgeInserts in order to make the buttons right aligned, similar to how Google Material aligns "flat buttons" in Material alerts and dialogues:

    screen shot 2017-12-05 at 7 53 52 pm

    What did you expect to happen?

    Buttons to align to the right of the view

    What happened instead?

    Buttons are always centered and take over the full width of the view, presumably because there is some auto-layout config going on.

    Thoughts? Love this library for its ease of use, and ability to add images, but would be really nice if it was just a little more flexible in this way.

    Changing blurEnabled and opacity for a single instance of PopupDialog

    I have a need to change PopupDialogOverlayView.blurEnabled and .opacity for a single instance of PopupDialog, and not for others. While I can change PopupDialogOverlayView.appearance() before and after I use the dialog, that is a bit hacky and I would like to figure out the cleanest way to change these parameters for a single instance.

    If this is not possible now then I would like to have this feature added if possible.

    • Language (Swift)

    • In case of Swift - Version (5)

    • Dependency manager (CocoaPods)

    I have a custom PopupDialog, I changed the appearance of the DefaultButton using the following lines of code:

    let db = DefaultButton.appearance()
         db.titleFont   = .optionsFont
         db.titleColor  = UIColor.optionsColor
         db.buttonColor = UIColor.buttonColor
    

    I need to set different colors appearance when the text field is empty. Then, when user starts typing I need to change the colors.
