Titanium is fantastic for building cross-platform mobile apps, but there are times when you absolutely need to get to a native property or method in a UI component and can't wait for it to be added to the next version of the SDK. This has happened to me often enough that I created the TiUIEx module to collect up these enhancements in one place. Right now, the module provides the following extensions for iOS:
TabGroup
tintColor property to set the bar tintselectedImageTintColor property to set the tint of the select tab
item imageImageView
contentMode property to set scaling and image placement.clipsToBounds property to control image clipping.See the iOS docs for complete details of the additions.
Version 1.0, Titanium SDK 3.0.0.GA (requires iOS 5.0 or later)
