IOS deletes dynamically created UIButton via tag
// Start button let btnStart=UIButton() btnStart.tag=100 // The point is here btnStart.frame=CGRectMake(CGRectGetMidX(self.frame) / 2 + 25, CGRectGetMidY(self.frame) / 2 + 30, 100, 40) btnStart.setTitle(" Begin ",forState: UIControlState.Normal) btnStart.backgroundColor=UIColor.blueColor() self.view?.addSubview(btnStart)
Delete via tag
The reason for deleting in this way is that the UIButton created when switching Scence does not disappear, and the operation for Scence is not inside 1 method
Recently, I started to study swift development and iOS development from scratch, and I am not skilled. Please correct me!
