Practice #用mask設計特別形狀的影片

上次用mask作出了大聯盟logo結合朗神背影的照片，再來就進階一點讓他變成影片吧

朗神眾多比賽中，我印象最深刻的就是2009年WBC的冠軍戰，日本與韓國鏖戰到10局，最後朗神敲出超前比數的安打，日本奪得冠軍的比賽

在Youtube找到比賽片段

因為是WBC，所以就用WBC的logo當作mask

這次直接寫在Project，方便把影片播出

import UIKit
import AVFoundation
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let wbcImage = UIImage(named: "wbc")
let wbcImageView = UIImageView(image: wbcImage)
let ichiroUrl = URL(string: "https://bit.ly/2OQloac")
let ichiroPlayer = AVPlayer(url: ichiroUrl!)
let ichiroPlayerLayer = AVPlayerLayer(player: ichiroPlayer)
ichiroPlayerLayer.videoGravity = .resizeAspectFill
view.layer.addSublayer(ichiroPlayerLayer)
ichiroPlayerLayer.frame = CGRect(origin: CGPoint(x: 50, y: 150), size: wbcImageView.frame.size)
ichiroPlayerLayer.mask = wbcImageView.layer
ichiroPlayer.play()
}
}
