Bubble pickers, inspired by Apple

Requirements:

iOS 9.1+
XCode 8.0+
Swift 3.0

Installation

AmazingBubbles Library is available through CocoPods. To install, add the following line to your Podfile:


                                              
                                                pod ‘AmazingBubbles’, ‘~> 0.0’

Usage:

Import library as follows:


                                              
                                                import AmazingBubbles

Add ContentBubblesView to your VC;
Add delegate and dataSource for ContentBubblesView instance:


                                              
                                                class ViewController: UIViewController {
@IBOutlet weak var bubblesView: ContentBubblesView! {

didSet {

bubblesView.delegate = self

bubblesView.dataSource = self

}

}
}

Implement protocols :


                                              
                                                public protocol ContentBubblesViewDelegate: class {

func minimalSizeForBubble(in view: ContentBubblesView) -> CGSize

func maximumSizeForBubble(in view: ContentBubblesView) -> CGSize
func contentBubblesView(_ view: ContentBubblesView, didSelectItemAt index: Int)

func contentBubblesView(_ view: ContentBubblesView, shouldChangeSizeForItemAt index: Int) -> Bool

func contentBubblesView(_ view: ContentBubblesView, didChangeSizeForItemAt index: Int)

}
public protocol ContentBubblesViewDataSource: class {

func countOfSizes(in view: ContentBubblesView) -> Int
func numberOfItems(in view: ContentBubblesView) -> Int

func addOrUpdateBubbleView(forItemAt index: Int, currentView: BubbleView?) -> BubbleView

}

for example:


                                              
                                                extension ViewController: ContentBubblesViewDataSource {

func countOfSizes(in view: ContentBubblesView) -> Int {

return 3

}
func numberOfItems(in view: ContentBubblesView) -> Int {

return 15

}
func addOrUpdateBubbleView(forItemAt index: Int, currentView: BubbleView?) -> BubbleView {

var view: BubbleView = currentView ?? BubbleView()

view.backgroundColor = .clear

let randomOrigin = CGPoint(x: CGFloat(drand48() * Double(self.view.frame.width * 2 / 3)),

y: CGFloat(drand48() * Double(self.view.frame.height * 2 / 3)))

view.frame = CGRect(origin: randomOrigin,

size: .zero)

return view

}

}

And than call:


                                              
                                                bubblesView.reload(randomizePosition: true)

Additional features:

You can create custom views by subclassing BubbleView
You can enable/disable gestures in ContentBubblesView:


                                              
                                                bubblesView.tapEnabled = true

bubblesView.panEnabled = false

Also you can change some settings in BubbleConstants struct or play with some settings of UIDynamicBehaviors.
