#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

1. 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.

2. Will have unexpected behavior if it's super view is not the root view of your view controller.

3. 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)
}
