动态隐藏状态栏

Question

我想在点击按钮时隐藏状态栏。我试过了：

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade];

我没有运气。我错过了什么吗？

Answer 1

简单的方法是，转到info.plist文件。添加行，“查看基于控制器的状态栏外观”并设置为NO。检查作为答案

Answer 2

仅用于在代码中进行切换：

-(void)statusBarShouldHide:(bool)hide{

    hideStatusBar = hide;
    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {
        [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
    }
}
-(bool)prefersStatusBarHidden{
    return hideStatusBar;
}

呼叫者：

[self statusBarShouldHide:true];

Answer 3

如果你想编程的话 试试这个。

覆盖功能

-(BOOL) prefersStatusBarHidden {
    return needHideStatusBar;
}

-(IBAction) checkStatus {

    // do your judgment here 

    needHideStatusBar = YES;
    if ([self 
        respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {
        [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
    }
}
