以编程方式禁用Alertview

Question

我想在没有按钮的AlertView中显示活动指示器，我想在活动指示停止动画时禁用它。

Answer 1

只需为UIAlertView调用dismissWithClickedButtonIndex:animated:方法

[alertView dismissWithClickedButtonIndex:0 animated:YES];

Answer 2

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Title" message:@"Message" delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
UIActivityIndicatorView *progress= [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(125, 50, 30, 30)];
progress.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;
[alert addSubview:progress];
[progress startAnimating];
[alert show];
[progress release];

然后关闭警报视图和微调器:(您需要将警报视图作为成员）

[alert dismissWithClickedButtonIndex:0 animated:YES];
[alert release];

Answer 3

只需致电：

[theAlertViewInstance dismissWithClickedButtonIndex: 0 animated:YES];

这应该做，你需要什么。
