"Delegate: self cancelButtonTitle: @" cancel "destructiveButtonTitle: @" OK "otherButtonTitles: nil, nil];
[Sheet showInView: self. view]; (3) effect 2. System pop-up box-middle pop-up box (1) usage: handle general notifications. If not necessary, try not to use them, affecting friendliness. (2) Example: UIAlertView * alert = [[UIAlertView alloc] initWithTitle: @ "warning" message: @ "incorrect account or password" delegate: nil cancelButtonTitle: @ "OK" otherButtonTitles: nil, nil];
[Alert show]; (3) effect: On the logon page, enter the account and password. If an error is entered, a prompt is displayed, you must click "OK" to re-enter 3.
