ios - ios隐藏带有动画的状态栏

Question

我想在页面更改时禁用导航栏动画。

根viewController

- (BOOL)prefersStatusBarHidden{
    return YES;
}
- (void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];
    [self.navigationController setNavigationBarHidden:YES animated:animated];,
}

推送viewController

- (BOOL)prefersStatusBarHidden{
    return NO;
}
- (void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];
    [self.navigationController setNavigationBarHidden:NO animated:animated];,
}

如果两个页面的statusBarHidden都等于NO或YES，则此方法有效，但是当我禁用其中之一时，会出现问题。由于我的声誉非常低，我无法上传图片，请检查图片链接。

Answer 1

您应该使用此选项卡对我有用

NSTimer *timer;
if([UIApplication sharedApplication].statusBarHidden == YES)
{
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];
    timer= [NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:@selector(hideStatusbar) userInfo:nil repeats:NO];
}

调用方法

-(void)hideStatusbar
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
}
