状态栏 导航栏 tabbar背景色&字体颜色设置

状态栏样式设置：ios9后要在info.plist中设置View controller-based status bar appearance==NO，默认是YES，设置后修改状态栏的样式代码才管用，
[[UIApplicationsharedApplication]setStatusBarStyle:UIStatusBarStyleLightContentanimated:NO];或在对应的viewcontroller中：

-(UIStatusBarStyle)preferredStatusBarStyle

{

    returnUIStatusBarStyleLightContent;

    

}

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

    // Override point for customization after application launch.

    

    [[UINavigationBarappearance]
setBarTintColor:[UIColorblueColor]];//导航栏颜色

    [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]]; //导航栏返回按钮（除标题）等其他地方的颜色

    [[UINavigationBarappearance]setTitleTextAttributes:@{NSFontAttributeName:[UIFontsystemFontOfSize:20],NSForegroundColorAttributeName:[UIColorredColor]}];//导航栏标题颜色&字体，在对应的viewcontroller中用self.title
= @"测试";

//

    [[UITabBarappearance]
setTintColor:[UIColorredColor]];//tabbar选中文字颜色

    [[UITabBarappearance]setBarTintColor:[UIColorblueColor]];//整个tabbar的颜色

    [[UIApplicationsharedApplication]
setStatusBarStyle:UIStatusBarStyleLightContentanimated:NO];//状态栏样式

return YES;
