Summary: Creating and deallocating UISegmentedControl (e.g by navigating back and forth to a view controller) which has style=Bar, tintColor set and only segments with titles added leaks CGImage/UiResizeableImage over time. This is notable with Instruments. Steps to Reproduce: Run an app with the sample code below. //code segmentedControl=[[UISegmentedControl alloc] initWithFrame:rect]; [segmentedControl setSegmentedControlStyle:UISegmentedControlStyleBar]; [segmentedControl setTintColor:[UIColor redColor]]; [segmentedControl insertSegmentWithTitle:@"Button 1" atIndex:0 animated:NO]; [segmentedControl insertSegmentWithTitle:@"Button 2" atIndex:1 animated:NO]; //end of code Expected Results: Number of live CGImage/UiResizeableImage instances should remain the same as new UISegmentedControl instances allocated/deallocated. Actual Results: Number of live CGImage/UiResizeableImage instances increases over time. Regression: Works fine in iOS 5.1 Notes: Also works as expected (no leaks) when tintColor is not set.

I've just run into this on iOS 6.1. I didn't notice it when the segmented control was added to a navigation bar as the titleView of a navigation item, but when I add it directly as a subview I see this problem.
