iphone - 以编程方式禁用 Alertview

Question

我想在没有按钮的 AlertView 中显示一个事件指示器，我想在事件指示器停止动画时禁用它。

Answer 1

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 View 和微调器:(您需要使警报 View 成为成员)

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