添加activityindicatorin alertVIew

Question

我想在alertView中添加一个活动指示器。 怎么做？

Answer 1

我认为你可以做到这一点 -

    UIAlertView *alertview = [[UIAlertView alloc] initWithTitle:@"title" message:@"\n\n" delegate:nil cancelButtonTitle:@"cancel" otherButtonTitles:nil];
    UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(130.0f, 50.0f, 20.0f, 20.0f)];
    [activityIndicator startAnimating];
    [alertview addSubview:activityIndicator];
    [alertview show];
    [alertview release];
    [activityIndicator release];

Answer 2

UIAlertView *alert;



alert = [[[UIAlertView alloc] initWithTitle:@"Configuring Preferences\nPlease Wait..." message:nil delegate:self cancelButtonTitle:nil otherButtonTitles: nil] autorelease];
[alert show];

UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

// Adjust the indicator so it is up a few pixels from the bottom of the alert
indicator.center = CGPointMake(alert.bounds.size.width / 2, alert.bounds.size.height - 50);
[indicator startAnimating];
[alert addSubview:indicator];
[indicator release];
