ios - 将 UIAlertView 用于 GetReady 标题

Question

我正在尝试使用 UIAlertView 调出准备就绪的标题，然后将其拉出屏幕，让玩家知道游戏开始了。我如何使用 UIAlertView 执行此操作？

Answer 1

试试这个方法...

UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:@"Get Ready!" message:nil     delegate:nil cancelButtonTitle:nil otherButtonTitles:nil];;

[alertView show];

[self performSelector:@selector(dismissReadyAlert:) withObject:alertView afterDelay:3.0];

-(void)dismissReadyAlert:(UIAlertView *)alertView
{
   [alertView dismissWithClickedButtonIndex:0 animated:NO];

   alertView.title = @"Your game is started!";

   [alertView show];

   [self performSelector:@selector(dismissStartAlert:) withObject:alertView afterDelay:2.0];
}

-(void)dismissStartAlert:(UIAlertView *)alertView
{
    [alertView dismissWithClickedButtonIndex:0 animated:YES];
}

谢谢!
