Introduction

This thing let's you mimic Apples UIAppearance thing back on iOS 4

Installation

• You need cocoapods lib manager
• Edit your Podfile and add

dependency 'TKAppearance', :podspec => 'https://raw.github.com/xslim/TKAppearance/master/TKAppearance.podspec'

• #import "TKAppearance.h"
• Dont forget to add -fno-objc-arc to all .m files in Target - Build Phases

Now you can do something like this on iOS 4:

[[UINavigationBar appearance] setTintColor:[UIColor redColor]];

UIImage *bgImg = [Decorator backgroundImageForNavigationBarWithSize:CGSizeMake(320.f, 44.f)];
[[UINavigationBar appearance] setBackgroundImage:bgImg forBarMetrics:UIBarMetricsDefault];

[[UINavigationBar appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                          [UIFont fontWithName:@"KPNSans-Bold" size:20.0], TKTextAttributeFont,
                                                          //[UIColor redColor], TKTextAttributeTextColor,
                                                          [UIColor styledShadowColor], TKTextAttributeTextShadowColor,
                                                          nil]];

bgImg = [Decorator backgroundImageForTabBarWithSize:CGSizeMake(320.f, 50.f)];
[[UITabBar appearance] setBackgroundImage:bgImg];

CGFloat w = 320.f / self.tabBarController.viewControllers.count -4;
bgImg = [Decorator backgroundImageForSelectedTabBarItemWithSize:CGSizeMake(w, 48.f)];
[[UITabBar appearance] setSelectionIndicatorImage:bgImg];

bgImg = [Decorator imageWithSize:CGSizeMake(320.f, 44.f) gradientStart:[UIColor styledTintEndColor] end:[UIColor styledSelectedTintStartColor]];
[[UISearchBar appearance] setBackgroundImage:bgImg];

[[UISwitch appearance] setOnTintColor:[UIColor styledButtonTintColor]];

Note: Tested on iOS 4.3
