Swift - 启动画面放大淡出效果的实现2（使用LaunchScreen.storyboard）

           

import UIKit

class ViewController: UIViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        //播放启动画面动画
        launchAnimation()
    }
    
    //播放启动画面动画
    private func launchAnimation() {
        //获取启动视图
        let vc = UIStoryboard(name: "LaunchScreen", bundle: nil)
            .instantiateViewController(withIdentifier: "launch")
        let launchview = vc.view!
        let delegate = UIApplication.shared.delegate
        delegate?.window!!.addSubview(launchview)
        //self.view.addSubview(launchview) //如果没有导航栏，直接添加到当前的view即可
        
        //播放动画效果，完毕后将其移除
        UIView.animate(withDuration: 1, delay: 1.5, options: .beginFromCurrentState,
        animations: {
                launchview.alpha = 0.0
                let transform = CATransform3DScale(CATransform3DIdentity, 1.5, 1.5, 1.0)
                launchview.layer.transform = transform
        }) { (finished) in
            launchview.removeFromSuperview()
        }
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}
