UIButton that displays an activity indicator when disabled.

The demo/ folder contains a demo project showing UIButton+Activity in use. Open and run it.

Import "UIButton+Activity.h". Then, on any button you want to show an activity indicator when disabled, either call

[_button useActivityIndicator:YES];

If your button lives in a storyboard/xib, you can also set the property on it there.

The activity indicator usually works best if you also set up the button to hide its title in the disabled state:

[_button setTitle:@"" forState:UIControlStateDisabled];

Then, to show the activity indicator, just disable the button as normal:

_button.enabled = NO;

This class has been tested back to iOS 6.0.

This class is implemented by hiding and showing a UIActivityIndicator subview when the button's enabledness changes.
