iOS 5: Curious about UIAppearance

Question

On the tech talk 2011 I saw a speech about the new UIAppearance protocol. There is not a lot of documentation out there yet. I will shortly summarize what I re

Answer 1

a: The following line

 [[UITableView appearance] setBackgroundColor:[UIColor blueColor]];

Will make every table view blue! Just tested on iOS 5 simulator.

b: The UIAppearance should work on every property on a UIView. All the subclasses of UIView conforms to UIAppearance Protocol

c: I think that the most of will create an class and or method that will customize the appearance and will call it in:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

Something like: [ApplicationAppearance setApplicationSchemaTo:ASchemaBlue];

Edit:

For example, UIBarButtonItem defines these methods:

@property(nonatomic,retain) UIColor *tintColor UI_APPEARANCE_SELECTOR;

From UIAppearanceContainer Protocol Reference

And in the UIBarButtonItem Class Reference the tintColor is defined

@property(nonatomic, retain) UIColor *tintColor

But in the UIBarButtonItem.h is defined:

@property(nonatomic,retain) UIColor *tintColor __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_5_0) UI_APPEARANCE_SELECTOR;

I think that the docs are not up to date.
