background-image

I am currently working with the iPhone SDK.

I have a NSTimer that changes the background image of a NSButton. Once this is complete, it will trigger the same action again (reset the NSTimer) for a predetermined number of times.

My problem is that if my NSTimer is set to execute more than once per second. (0.75, say) The background image wont change.

I am using NSLog to check that the event fires. But the button image will just remain in its original state.

Is there any way to change the background image more often than once per second?

Thanks.
