iOS开发之--隐藏状态栏

1，全局隐藏

在Targets->General->勾选中Hide status bar .，如下图：

2.单个页面隐藏/展示状态栏

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];
}

仅做记录！
