我在“didFinishLaunchingWithOptions”方法中创建动画闪屏 . 动画启动画面持续时间为2秒 . 两秒钟后，我隐藏了动画启动画面 . 当动画屏幕出现时我想隐藏状态栏，当动画屏幕消失时，我想显示状态栏 .

怎么做？

  • （BOOL）应用程序：（UIApplication *）application didFinishLaunchingWithOptions：（NSDictionary *）launchOptions {

//我在这里创建动画启动画面

**** ********* 这里我要隐藏状态栏* **********

splashView =[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 580)];
    splashView.backgroundColor =[UIColor whiteColor];
    [self.window addSubview:splashView];


    logoView = [[UIImageView alloc] initWithFrame:CGRectMake(logoX,0, 225, 25)];
    logoView.image = [UIImage imageNamed:@"logoImage"];
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:2.0];
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:window cache:YES];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(startupAnimationDone:finished:context:)];
    splashView.alpha = 1.0;
    logoView.frame = CGRectMake(logoX, logoY, 225, 25);

    [window addSubview:logoView];
    [window bringSubviewToFront:logoView];

    [UIView commitAnimations];

//隐藏动画启动画面2秒钟后

- (void)startupAnimationDone:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
    ************* Here i want to show  Status bar Again ***************
    [splashView removeFromSuperview];
    [logoView removeFromSuperview];
}

    在plist文件中添加以下条目：

    • "Status bar is initially hidden" =是：隐藏应用程序启动时和启动屏幕中的状态栏

    • "View controller-based status bar appearance" =否：防止视图控制器类显示状态栏

    您可以为UIViewController创建一个类别

    @implementation UIViewController (HideStatusBar)
-(BOOL)prefersStatusBarHidden
{
return YES;
}

    你进入ProjectSettings - > General . 有一个选项 Status Bar Style .

    enter image description here

    EDIT 使用块 . 它们为动画提供了非常简单的语法 .

    [UIView animateWithDuration:2.0 delay:0 options:UIViewAnimationOptionCurveEaseIn animations:^{
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade];

     //your animation code here
     //all changes made here to frame, bounds, alpha etc. are animated

  } completion:^(BOOL finished) {
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];

     //this is called after animation finishes

  }];
