最近做直播韧献，有個(gè)截屏的需求舌劳，按照網(wǎng)上的方法截屏后畫面沒有圖像！找了好久終于找到了解決辦法军洼！
寫個(gè)extension巩螃，然后我是用 ViewController.view.getViewShot() 就OK了！匕争！
extension UIView {
func getViewShot() -> UIImage? {
UIGraphicsBeginImageContextWithOptions(self.bounds.size, false, UIScreen.main.scale)
self.drawHierarchy(in: self.bounds, afterScreenUpdates: false)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image
}
}
