設(shè)置statusBar,navigationBar,tabBar的顏色
//AppDelegate.m
//設(shè)置navigationBarColor
[[UINavigationBar appearance] setTranslucent:YES];
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:128/255.0f green:128/255.0f blue:128/255.0f alpha:1.0]];
// 設(shè)置tabBarColor
[[UITabBar appearance] setTranslucent:NO];
[[UITabBar appearance] setBarTintColor:[UIColor colorWithRed:128/255.0f green:128/255.0f blue:128/255.0f alpha:1.0]];
// 設(shè)置status文字顏色
[[UIApplication sharedApplication] setStatusBarHidden:NO];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
此外号杠，需要在.plist文件增加一行:
View controller-based status bar appearance = NO
表示viewController不對status bar進行操作。
