Big activity indicator on iPhone

Question

Does anyone know how to show a rounded squared with a spinning activity indicator? It is used in many apps. If you don't know what im talking about, it looks like the indicator when you change volume on your Mac but with a darker background. Im not sure if it is built-in to iOS or someone made it.

Like the one in this post but not full screen just the activity indicator How to create a full-screen modal status display on iPhone?

Answer 1

Here's what I use when I want to show that kind of indicators.

UIView *loading = [[UIView alloc] initWithFrame:CGRectMake(100, 200, 120, 120)]; 

loading.layer.cornerRadius = 15;
loading.opaque = NO;
loading.backgroundColor = [UIColor colorWithWhite:0.0f alpha:0.6f];

UILabel *loadLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 25, 81, 22)];

loadLabel.text = @"Loading";
loadLabel.font = [UIFont boldSystemFontOfSize:18.0f];
loadLabel.textAlignment = UITextAlignmentCenter;
loadLabel.textColor = [UIColor colorWithWhite:1.0f alpha:1.0f];
loadLabel.backgroundColor = [UIColor clearColor];

[loading addSubview:loadLabel];
[loadLabel release];

UIActivityIndicatorView *spinning = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
spinning.frame = CGRectMake(42, 54, 37, 37);
[spinning startAnimating];

[loading addSubview:spinning];
[spinning release];

loading.frame = CGRectMake(100, 200, 120, 120);

Then you just add the 'loading' view to the view of your choice and you got it.

Hope this is what you needed.
