(70) how to set the style of the status bar and navigation bar for Xcode5 or above, xcode5

[Status Bar]

Before Xcode5, the status bar is managed through the UIApplication singleton. After that, the status bar is managed by the Controller by default. If the Controller has NavigationController, set the status bar in NavigationController and call the following method:

- (UIStatusBarStyle)preferredStatusBarStyle;

If you want the status bar to still be set through Singleton, you can add a key value to info. plist:

View controller-based status bar appearance. The value is NO.

In this way, you can set the status bar through the UIApplication singleton:

[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

[Navigation bar]

The topic in the navigation bar is set globally. You can use the appearance of UINavigationBar to get the NavigationBar and then set the style:

    UINavigationBar *navBar = [UINavigationBar appearance];    NSMutableDictionary *attrs = [NSMutableDictionary dictionary];    attrs[NSForegroundColorAttributeName] = [UIColor whiteColor];    attrs[NSFontAttributeName] = [UIFont systemFontOfSize:16];    [navBar setTitleTextAttributes:attrs];
