What properties can I set via an UIAppearance prox

Question

What properties can I set via an UIAppearance proxy? Apple's UIKit documentation does not list them. Is there a list of these properties?

Answer 1

Properties that can be set via UIAppearance are tagged with UI_APPEARANCE_SELECTOR in the corresponding header file.

To generate a list of properties tagged with UI_APPEARANCE_SELECTOR, you can use the following unix commands in a terminal:

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer‌​/SDKs/iPhoneOS5.1.sdk/System/Library/Frameworks/UIKit.framework/Headers
grep -H UI_APPEARANCE_SELECTOR ./* | sed 's/ __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_5_0) UI_APPEARANCE_SELECTOR;//'

Here is a list that I compiled using the above commands. This is for the 5.0 SDK. The corresponding getter methods have been omitted for brevity.
