压缩厉害
最终效果，压缩厉害
<br />
1、UI布局
ViewController上面部分包括一个CollectionView，下面是一张背景图和一个Button
如图
<br />
第二个界面:拖入一个VisualEffectView，然后在里面添加Button和Label，完成如下图的布局
<br />
<br />
2、实现
实现原理，修改系统默认的动画弹出方式（设置代理，自己去实现代理方法），然后把要显示的ViewController中的控件做动画效果（分为左右两边，先移出到屏幕外，在使用动画效果进入屏幕）
在ViewController中创建数据源，设置代理，实现代理方法

import UIKit
struct model {
var icon = "animator1.jpg"
var name = "default"
var backImage = "animator1.jpg"
}
class ViewController: UIViewController ,UICollectionViewDelegate,UICollectionViewDataSource{
@IBOutlet weak var collectionView: UICollectionView!
let data = [
model(icon: "Chat", name: "小明", backImage: "animator1.jpg"),
model(icon: "Quote", name: "老王", backImage: "animator2.jpg"),
model(icon: "Audio", name: "隔壁大叔", backImage: "animator3.jpg"),
model(icon: "Link", name: "邻家淑女", backImage: "animator4.jpg")
]
override func viewDidLoad() {
super.viewDidLoad()
collectionView.delegate = self
collectionView.dataSource = self
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return .LightContent
}
@IBAction func unwindToMainViewController (sender: UIStoryboardSegue){
self.dismissViewControllerAnimated(true, completion: nil)
}
}
extension ViewController {
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int{
return 10
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell{
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("collCell", forIndexPath: indexPath) as! CollectionViewCell
let model = data[indexPath.row % 4]
cell.backImage.image = UIImage(named: model.backImage)
cell.icon.image = UIImage(named:model.icon)
cell.nameLabel.text = model.name
return cell
}
}
在第二个ViewController中依次把每个控件都拖入到Controller中，设置动画代理

class MenuViewController: UIViewController {
@IBOutlet weak var audioLab: UILabel!
@IBOutlet weak var audioBtn: UIButton!

@IBOutlet weak var photoLab: UILabel!

override func viewDidLoad() {
super.viewDidLoad()
transitioningDelegate = animator
}
override func didReceiveMemoryWarning() {

创建一个类，用于实现动画效果

let container = transitionContext.containerView()
