如何在iOS 7中使用动画隐藏状态栏？ [英] How to hide status bar with animation in iOS 7?

问题描述

自iOS 7推出以来，我无法像iOS 6一样显示或隐藏动画状态栏。
现在我使用NSTimer来控制它何时隐藏。

Since iOS 7 rolled out, I can't show or hide status bar with animation just like in iOS 6. For now I use NSTimer to control it when to hide.

这是我的代码：

- (void)hideStatusBar{
    _isStatusBarHidden=YES;
    [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
}
- (void)showStatusBar{
_isStatusBarHidden=NO;
[self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
}
    //===================
 _controlVisibilityTimer = [[NSTimer scheduledTimerWithTimeInterval:4 target:self selector:@selector(hideStatusBar:) userInfo:nil repeats:NO] retain];

但不幸的是，状态栏隐藏的方式看起来有点粗糙，没有消失。有人在那里有解决方案吗？

But unfortunately the way of status bar hiding seems a little bit rough, not fading away. Is someone out there has a solution to this ?

我使用@hahaha解决了隐藏问题解。我只需要一个视图作为状态栏的背景，这是我的代码。

I solved the hiding issue, using @hahaha solution. I just need a view to be the background of the status bar, here is my code.

AppDelegate* appDelegate = (AppDelegate*)[[UIApplication sharedApplication]delegate];

self.StatusBarOrange = [[UIView alloc] initWithFrame:CGRectMake(0, 0, appDelegate.window.frame.size.width, 20)];    
[self.StatusBarOrange setBackgroundColor:[UIColor orangeColor]];
[appDelegate.window.rootViewController.view addSubview:self.StatusBarOrange];

现在一切正常！

推荐答案

您需要致电

[UIViewController setNeedsStatusBarAppearanceUpdate];

来自动画块内，如下例所示：

from within an animation block as in the following example:

@implementation SomeViewController {
    BOOL _statusBarHidden;
}

- (BOOL)prefersStatusBarHidden {
    return _statusBarHidden;
}

- (void)showStatusBar:(BOOL)show {
 [UIView animateWithDuration:0.3 animations:^{
        _statusBarHidden = !show;
        [self setNeedsStatusBarAppearanceUpdate];
    }];
}

@end
