同时隐藏状态栏和导航栏,就像在图片应用程序中一样

Question

我有一个包含大量文本的视图,所以我希望允许用户在单击时隐藏statusBar + navigationBar.我真的很喜欢图片应用程序中的隐藏风格,其中statusBar和navigationBar隐藏在一起(不滑动,只是淡出),有一些animationDuration,所以我尝试做类似的事情.这是我在touchesDidBegan方法中所做的:

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent];
    [UIView setAnimationDuration:0.5];
[UIView beginAnimations:@"" context:nil];
    [[UIApplication sharedApplication] setStatusBarHidden:!([UIApplication sharedApplication].statusBarHidden) withAnimation:UIStatusBarAnimationNone];
    [self.navigationController setNavigationBarHidden:(!self.navigationController.navigationBarHidden) animated:NO];
    [UIView commitAnimations];
    self.navigationController.navigationBar.translucent = !self.navigationController.navigationBar.translucent; // this is needed to make bars appear on top of my view.
}

但这并不能同时隐藏条形图.它让它们向下滑动.它与上述方法的版本具有相同的效果:

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent];
    // deleted UIView animation, changed animation type to "slide"
    [[UIApplication sharedApplication] setStatusBarHidden:!([UIApplication sharedApplication].statusBarHidden) withAnimation:UIStatusBarAnimationSlide];
    // enabled animation for navBar
    [self.navigationController setNavigationBarHidden:(!self.navigationController.navigationBarHidden) animated:YES];
    self.navigationController.navigationBar.translucent = !self.navigationController.navigationBar.translucent; // this is needed to make bars appear on top of my view.
}

如果我摆脱UIView动画并隐藏没有动画的条形图,它们会隐藏并同时显示,但速度太快.也许我走错了方向.如果有人可以帮我解决这个问题,我将不胜感激.

编辑:搞定了

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    // don't forget to set navigationBar.translucent to YES
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent];
    [UINavigationBar setAnimationDuration:3.0];

    [UINavigationBar beginAnimations:@"" context:nil];
    [[UIApplication sharedApplication] setStatusBarHidden:!([UIApplication sharedApplication].statusBarHidden) withAnimation:NO];
    if ([UIApplication sharedApplication].isStatusBarHidden)
        [self.navigationController.navigationBar setAlpha:0.0];
    else [self.navigationController.navigationBar setAlpha:1.0];
    [UINavigationBar commitAnimations];
}

检查https://github.com/kirbyt/KTP​​hotoBrowser的演示，您可以在其中找到如何隐藏和显示状态栏和导航栏。

• 大多数情况下，您需要使用 NSTimer 设置 4 或 5 秒后自动隐藏 隐藏状态栏或导航栏

• 您还可以使用“触摸开始”来标记此计时器以随机显示或隐藏。

希望它能帮助您完成任务。使用 Barack 点查看上述 Github 链接的示例演示。您可以轻松找到隐藏和显示状态栏或导航栏的功能。
