ios - 有没有办法在一段时间后关闭无按钮 UIalertView？

Question

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"tittle"
               message:@""
                 delegate:self
              cancelButtonTitle:@""
              otherButtonTitles:nil];
  [alertView show];
  [alertView release];

我想在它显示一段时间后关闭 alerview，但是当 alertview 没有按钮时，如果我调用 -dismissWithClickedButtonIndex:animated: 方法 和- 它不起作用performSelector:withObject:afterDelay:还有其他方法可以解雇它吗？感谢您的任何想法!

Answer 1

-(void)xx  {
     [self performSelector:@selector(dismissAlertView:) withObject:alertView afterDelay:2];
}
-(void)dismissAlertView:(UIAlertView *)alertView{
    [alertView dismissWithClickedButtonIndex:0 animated:YES];
}

就是这样，我修好了
