如果你不希望你的视图控制器被状态栏(和导航栏)重叠，在Xcode 5的Interface Builder中取消选中“在顶部栏下扩展边缘”框。

如果你正在使用接口构建器，试试这个:

在你的xib文件中:

1)选择主视图，设置背景颜色为黑色(或任何你想要状态栏的颜色)

2) Make sure the background is a self contained subview positioned as a top level child of the controller's view. Move your background to become a direct child of the controller's view. Check the autosizing panel to be sure that you've locked all frame edges, activated both flexibility axes, and if this is a UIImageView, set the content mode to Scale to fill. Programmatically this translates to contentMode set to UIViewContentModeScaleToFill and has its auto resizing mask set to (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight).

3)现在将所有被锁定的东西上下移动20点，并设置iOS 6/7 delta Y为-20。 在自动缩放面板中，所有被锁定在顶部框架上的顶级子图层都需要向下移动20点，并将其iOS 6/7 delta Y设置为-20。(Cmd选择所有这些，并按下箭头20次-有更好的方法吗?)

4) Adjust the iOS 6/7 delta height of all of the above items that had a flexible height. Any of the items that were locked to the frame top and bottom and had flexible height enabled in the autosizing panel must also have their iOS 6/7 delta height set to 20. That includes the background view mentioned above. This may seem anti-intuitive, but due to the order in which these are applied, it is necessary. The frame height is set first (based on device), then the deltas are applied, and finally the autosizing masks are applied based upon the offset positions of all of the child frames - think it through for a bit, it will make sense.

5)最后，被锁定在底部框架而不是顶部框架的项目根本不需要delta。

这将给你在iOS7和iOS6中相同的状态栏。

另一方面，如果你想要iOS7样式同时保持iOS6兼容性，那么将背景视图的delta Y / delta height值设置为0。

我的解决方案是在iOS 7上，在窗口顶部添加一个高度为20点的UIView。 然后我在AppDelegate类中创建了一个方法来显示/隐藏“固态”状态栏背景。在应用程序:didFinishLaunchingWithOptions::

// ...

// Add a status bar background
self.statusBarBackground = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.window.bounds.size.width, 20.0f)];
self.statusBarBackground.backgroundColor = [UIColor blackColor];
self.statusBarBackground.alpha = 0.0;
self.statusBarBackground.userInteractionEnabled = NO;
self.statusBarBackground.layer.zPosition = 999; // Position its layer over all other views
[self.window addSubview:self.statusBarBackground];

// ...
return YES;

然后我创建了一个方法来淡入/淡出黑色状态栏背景:

- (void) showSolidStatusBar:(BOOL) solidStatusBar
{
    [UIView animateWithDuration:0.3f animations:^{
        if(solidStatusBar)
        {
            [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
            self.statusBarBackground.alpha = 1.0f;
        }
        else
        {
            [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
            self.statusBarBackground.alpha = 0.0f;
        }
    }];
}

我现在要做的就是在需要时调用[appDelegate showSolidStatusBar:YES]。

试试这个简单的方法....

步骤1:在单个viewController中更改

[[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleBlackOpaque];

步骤2:更改整个应用程序

info.plist
      ----> Status Bar Style
                  --->UIStatusBarStyle to UIStatusBarStyleBlackOpaque

第三步:在每个viewWillAppear中添加这个来调整iOS7的状态栏高度

    [[UIApplication sharedApplication]setStatusBarStyle:UIStatusBarStyleLightContent];
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 7) {
        CGRect frame = [UIScreen mainScreen].bounds;
        frame.origin.y+=20.0;
        frame.size.height-= 20.0;
        self.view.frame = frame;
        [self.view layoutIfNeeded];
    }

你可以一起隐藏状态栏。所以你的应用会是全屏的。我想这是你能得到的最好的了。

UIStatusBarStyleNone或目标设置。

我已经看了很多很多很多教程来解决这个该死的问题。但是没有一个有用!以下是我的解决方案，对我来说很管用:

if( [[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0f ) {
    float statusBarHeight = [[UIApplication sharedApplication] statusBarFrame].size.height;
    for( UIView *v in [self.view subviews] ) {
        CGRect rect = v.frame;
        rect.origin.y += statusBarHeight;
        v.frame = rect;
    }
}

逻辑很简单。我改变了所有孩子对自我的看法。视图为20像素。 这是所有。然后，屏幕截图就会像iOS 6一样显示出来。我讨厌iOS7的状态栏!~ " ~
