#JVFlowerMenu is a quick and easy replacement to a hamburger menu and possibly a UITabBar
The JVFlowerMenu is not a controller but rather a drop in UI element that you could then use to control the content of any UI View. Here is a quick example of the final product:
#Setup
Cocoapods
pod 'JVFlowerMenu'
#Limitations
-
Right now the classes are not @UIDesignable or @UIInspectable. This means that if you want to add them you have to add the constraints yourself in code or live and let live after you assign a frame.
-
Will have unexpected behavior if it's super view is not the root view of your view controller.
-
Any transforms you apply to the menu will mess up the behavior.
#Example
initalize a JVFlowerMenu like this:
let menu = JVFlowerMenu(withImage: nil, andTitle: nil)
Initalizing with a nil image will default to a drawing of a hamburger menu. A nil title wil just produce nothing for the title.
Then you can add Pedals like this:
menu.addPedal(withImage: nil, withTitle: nil)
menu.addPedal(withImage: nil, withTitle: nil)
menu.addPedal(withImage: nil, withTitle: nil)
If you pass nil for a Pedal image it will default to a drawing of a circle. nil for the title will display nothing.
You can then become the delegate and get notified about events in these methods:
menu.delegate = self
//MARK: Delegate Functions
public func flowerMenuDidSelectPedalWithID(_ theMenu: JVFlowerMenu, pedal: Pedal) {
print("\(pedal.ID) Selected")
}
public func flowerMenuDidExpand() {
print("Flower Menu expanded")
}
public func flowerMenuDidRetract() {
print("Flower Menu Retracted")
}
There are some properties you can change to manipulate the behavior of the menu:
menu.startAngle = 90.0
menu.pedalDistance = 200
menu.pedalSpace = 20
menu.stagger = 0
Finally, here is some set up code for adding constraints progmatically:
override func viewDidLoad() {
self.view.addSubview(menu)
self.constrain()
}
func constrain() {
var constraints = [NSLayoutConstraint]()
let vertical = NSLayoutConstraint.constraints(withVisualFormat: "V:|-30-[pedal]", options: [], metrics: nil, views: ["pedal": self.menu])
constraints.append(contentsOf: vertical)
let horizontal = NSLayoutConstraint.constraints(withVisualFormat: "H:|-20-[pedal]", options: [], metrics: nil, views: ["pedal": self.menu])
constraints.append(contentsOf: horizontal)
self.view.addConstraints(constraints)
}
