iOS开发——状态栏隐藏与显示statusBar

1. AppDelegate.m中调用系统单利

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    
    // 获取程序App单例对象
    [UIApplication sharedApplication].statusBarHidden = NO;
    [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;
    
    return YES;
}

2. ViewController.m中使用

// iOS7之后系统状态栏的定制是基于视图控制器。

// 配置状态栏显示类型
- (UIStatusBarStyle)preferredStatusBarStyle {
    
    return UIStatusBarStyleLightContent;
}

// 配置状态栏是否隐藏，默认为NO
- (BOOL)prefersStatusBarHidden {
    
    return YES;
}
