Simple class that let's you assign an image and spin it 360deg endlessly

eg. 

// initialization
ImageSpinner *spinner = [[ImageSpinner alloc] initWithImage:[UIImage imageNamed:@"example.png"]];

// Animation methods
[spinner startAnimation];
[spinner stopAnimation];

// Set another image
[spinner setImage:[UIImage imageNamed:@"example2.png"];

Note: The image will continue spinning to it's original position even when you call stop animation.
