iOS 隐藏状态栏

1.整个项目隐藏状态栏

在Targets->General->勾选中Hide status bar 

2.单个界面隐藏状态栏,例如登录注册页面

1.首先在info.plist里面View controller-based status bar appearance 设置为 NO.

2.在需要调控状态栏的ViewController类中添加以下代码:

//进入时隐藏

-(void)viewWillAppear:(BOOL)animated{ 

 [super viewWillAppear:animated];

//隐藏=YES,显示=NO; Animation:动画效果 

 [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];

}

//退出时显示

-(void)viewWillDisappear:(BOOL)animated{ 

 [super viewWillDisappear:animated];

//隐藏=YES,显示=NO; Animation:动画效果 

 [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];

}

3.启动页隐藏状态栏,进入程序后正常显示状态栏

1 .首先在Targets->General->勾选中Hide status bar或者在info.plist里面 Status bar is initially hidden 设置为 YES

2.在AppDelegate.m中添加代码

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

[application setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];

}
