- 给window添加手势
在application(_ application: , didFinishLaunchingWithOptions launchOptions: ?)里面
// 添加手势
let tapGesture = UITapGestureRecognizer(target: self, action: nil)
tapGesture.delegate = self
window?.addGestureRecognizer(tapGesture)
- 实现代理方法
extension AppDelegate: UIGestureRecognizerDelegate{
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
// User tapped on screen, do whatever you want to do here.
print("点击了屏幕")
return false
}
}
