iOS 7: UITableView显示在状态栏下

The first screen of my application is a UITableViewController without a navigation bar, which means that the content flows under the status bar so there's a lot of text collisions. I've adjusted both the properties for Under top bars and Adjust scroll view insets which do actually stop it from scrolling under, but at the cost of keeping the top of the table view under. I've attempted to set the UITableView frame to offset by 20 pixels, but it doesn't appear to take effect and as I currently need the app to be compatible with iOS 6 I can't jump to iOS 7 Storyboards to force autolayout to use the top height guide. Has anyone found a solution that works for both versions?

我尝试过的事情:设置edgesForExtendedLayout，在Storyboard中更改顶部栏下的设置和调整滚动视图，迫使框架到一个新的区域。

一图胜千言万语:

            self.edgesForExtendedLayout = UIRectEdgeNone;   // iOS 7 specific
        CGRect viewBounds = self.view.bounds;
        CGFloat topBarOffset = self.topLayoutGuide.length;
        viewBounds.origin.y = topBarOffset * -1;
        self.view.bounds = viewBounds;
        self.navigationController.navigationBar.translucent = NO;
    }
}

其他回答

如果你还需要支持iOS 6，你必须有条件地把它下移。也就是说，在iOS 7中，你只需要将它向下移动20个点(通过帧操作或使用自动布局)，而在iOS 6中，你可以不动它。我不相信你们能在IB中做这个，所以你们必须在代码中做。

EDIT

你可以在IB中，通过使用iOS6/iOS7增量。在iOS 7中设置你的位置，然后在iOS 6中设置Y为-20点。更多信息请参见这个SO问题。

我这样做的视网膜/非视网膜显示

BOOL isRetina = FALSE;

if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)]) {
    if ([[UIScreen mainScreen] scale] == 2.0) {
        isRetina = TRUE;
    } else {
        isRetina = FALSE;
    }
}

if (isRetina) {
    self.edgesForExtendedLayout=UIRectEdgeNone;
    self.extendedLayoutIncludesOpaqueBars=NO;
    self.automaticallyAdjustsScrollViewInsets=NO;
}

对于Xcode 7，取消导航栏的“半透明”复选标记对我来说很有效。

我在ios 11中遇到了这个问题，但ios 8 - 10.3.3的布局是正确的。对于我的案例，我设置垂直空间约束为Superview。Top Margin代替Superview。顶部适用于ios 8 - 11。
