Animated popover that pops out of a frame. You can specify the direction of the popover and the arrow that points to its origin. Color, border radius and font can be easily customized. This popover can be used to leave subtle hints about your UI and provide fun looking onboarding popups.

Versioning notes
With version 2.0.0
the library was re-written in Swift, and the API was slightly updated. Checkout version 1.5.x
for the previous Objective-C implementation.
Version 3.0.0
introduces Swift 4 support, 3.5.0
Swift 4.2.
Setup with CocoaPods
- Add
pod 'AMPopTip'
to yourPodfile
- Run
pod install
- Run
open App.xcworkspace
Setup with Carthage
- Add
github "andreamazz/AMPopTip"
- Run
carthage update
- Add
AMPopTip.framework
in your project
You can then import the framework in your project
import AMPopTip
Usage
The API is fairly straight forward, you can show and hide the popover at any time.
Showing the popover
You must specify the text that you want to display alongside the popover direction, its max width, the view that will contain it and the frame of the view that the popover's arrow will point to.
let popTip = PopTip()
popTip.show(text: "Hey! Listen!", direction: .up, maxWidth: 200, in: view, from: someView.frame)
You can also display the popover in the center, with no arrow, in this case the from
can be the whole view:
popTip.show(text: "Hey! Listen!", direction: .none, maxWidth: 200, in: view, from: view.frame)
Coordinate system
Please note that the frame you are intended to provide needs to refer to the absolute coordinate system of the view you are presenting the popover in. This means that if you are presenting the popover in a view, pointing to a nested subview, you'll need to convert its frame using UIKit's convertRect(_:toView:)
. Read the reference here.
Direction
You can specify the direction that the tip will occupy, or you can let the library decide by using auto
(all axis), autoHorizontal
(only left
or right
) or autoVertical
(only up
or down
). Once the popup is visible, the direction
property will hold the direction that was decided.
Showing a custom view
You can provide a custom view that will be wrapped in the PopTip and presented.
let customView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
// Configure your view
popTip.show(customView: customView, direction: .down, in: view, from: someView.frame)
Showing a custom SwiftUI view
You can provide a custom SwiftUI view that will be embed in a UIHostingController
, added to a parent controller and then wrapped in the PopTip and presented.
let customSwiftUIView = MySwiftUIView()
// Configure your view
popTip.show(rootView: customSwiftUIView, direction: .down, in: view, from: someView.frame, parent: someParentViewController)
Dismissing the popover
You can hide the popover by calling:
popTip.hide()
Or you can specify the duration of the popover:
popTip.show(text: "Hey! Listen!", direction: .up, maxWidth: 200, in: view, from: someView.frame, duration: 3)
You can also let the user dismiss the popover by tapping on it:
popTip.shouldDismissOnTap = true
You can add a block that will be fired when the user taps the PopTip...
popTip.tapHandler = { popTip in
print("\(popTip) tapped")
}
... when the popover is shown...
popTip.appearHandler = { popTip in
print("\(popTip) appeared")
};
... or when the popover is dismissed:
popTip.dismissHandler = { popTip in
print("\(popTip) dismissed")
}
popTip.tapOutsideHandler = { _ in
print("tap outside")
}
popTip.swipeOutsideHandler = { _ in
print("swipe outside")
}
Updating the PopTip
You can update the text, attributed text, or custom view to a PopTip already visible:
popTip.update(text: "New string")
popTip.update(attributedText: someAttributedString)
popTip.update(customView: someView)
The position can also be changed by updating the from
property:
let here = CGRect(x: 100, 100, 10, 10)
let there = CGRect(x: 400, 400, 10, 10)
popTip.show(text: "Hey! Listen!", direction: .up, maxWidth: 200, in: view, from: here)
DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
popTip.from = there
}
Custom entrance animation
You can choose which animation should be performed when the popTip is displayed:
popTip.entranceAnimation = .scale;
Available animations:
PopTipEntranceAnimation.scale,
PopTipEntranceAnimation.transition,
PopTipEntranceAnimation.none,
PopTipEntranceAnimation.custom
PopTipEntranceAnimation.custom
You can provide your own animation block when using PopTipEntranceAnimation.custom
:
popTip.entranceAnimationHandler = { [weak self] completion in
guard let `self` = self else { return }
self.popTip.transform = CGAffineTransform(rotationAngle: 0.3)
UIView.animate(withDuration: 0.5, animations: {
self.popTip.transform = .identity
}, completion: { (_) in
completion()
})
}
This sample makes the PopTip rotate on entrance. Make sure to call the completion block when the animation is done. Also note that the animation is fired as soon as the PopTip is added as subview.
Action animations
Action animations are subtle animations that can be performed to get the user's attention. Set your preferred animation:
popTip.actionAnimation = .bounce()
Available animations:
PopTipActionAnimation.bounce,
PopTipActionAnimation.float,
PopTipActionAnimation.pulse,
PopTipActionAnimation.none
The animation is fired as soon as the popover enters the scene and completes its entrance animation, if startActionAnimationOnShow
is set to true.
Customize the animations
You can pass a custom value as an associated value to customize the action animation:
popTip.actionAnimation = .bounce(16) // This will bounce for 16px instead of the default value
Customizing the arrow position
The arrow is centered by default, and moves to avoid the edge of the screen. You can manually change the offset from the center using the bubbleOffset
property.
A note about subviews
The popover is presented inside the view provided in the in
parameter. If this view is smaller than the resulting popover, to prevent clipping set clipsToBounds = false
on the presenting view, and set constrainInContainerView = false
to the pop tip instance. See #175 for more context.
Customization
Use the appearance proxy to customize the popover before creating the instance, or just use its public properties:
textColor = <#UIColor#>;
textAlignment = <#NSTextAlignment#>
bubbleColor = <#UIColor#>
borderColor = <#UIColor#>
borderWidth = <#CGFloat#>
cornerRadius = <#CGFloat#> // Popover's border radius
rounded = <#Bool#> // If set to YES the radius will equal frame.height / 2
offset = <#CGFloat#> // Offset between the popover and the origin
font = <#UIFont#>
padding = <#CGFloat#>
edgeInsets = <#UIEdgeInsets#>
arrowSize = <#CGSize#>
animationIn = <#TimeInterval#>
animationOut = <#TimeInterval#>
delayIn = <#TimeInterval#>
delayOut = <#TimeInterval#>
entranceAnimation = <#PopTipEntranceAnimation#>
actionAnimation = <#PopTipActionAnimation#>
actionAnimationIn = <#TimeInterval#>
actionAnimationOut = <#TimeInterval#>
actionDelayIn = <#TimeInterval#>
actionDelayOut = <#TimeInterval#>
edgeMargin = <#CGFloat#>
bubbleOffset = <#CGFloat#> // Offset between the bubble and the origin
arrowOffset = <#CGFloat#> // Offset between the bubble center and the arrow
arrowRadius = <#CGFloat#>
shadowOpacity = <#Float#>
shadowRadius = <#Float#>
shadowOffset = <#CGSize#>
shadowColor = <#UIColor#>
