UIAlertView 自动dismiss? (先设NSTimer，后调用Delegate)

- (void) performDismiss: (NSTimer *)timer

{

    [baseAlert dismissWithClickedButtonIndex:0 animated:NO];//important

    [baseAlert release];

    baseAlert = NULL;

}

 

- (void) presentSheet

{

    baseAlert = [[UIAlertView alloc]

                              initWithTitle:@"Alert" message:@"\nMessage to user with asynchronous information"

                              delegate:self cancelButtonTitle:nil

                              otherButtonTitles: nil];

    [NSTimer scheduledTimerWithTimeInterval:1.0f target:self selector: @selector(performDismiss:)

                                   userInfo:nil repeats:NO];

    [baseAlert show];

}
