我认为使用UITableViewController的方法可能和你们之前做的有点不同。这对我来说很有效，但你可能不会喜欢。我所做的是有一个视图控制器和一个指向UItableViewController的容器视图。这样我就可以使用TopLayoutGuide提供给我的故事板。只要把约束添加到容器视图，你就可以兼顾iOS7和iOS6了。

我使用一个UISplitViewController与一个导航控制器和一个tableviewcontroller。在尝试了许多解决方案后，这对我来说很有效:

float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
if (systemVersion >= 7.0f) {

    // Move the view down 20 pixels
    CGRect bounds = self.view.bounds;
    bounds.origin.y -= 20.0;
    [self.navigationController.view setBounds:bounds];

    // Create a solid color background for the status bar
    CGRect statusFrame = CGRectMake(0.0, -20.0, bounds.size.width, 20);
    UIView* statusBar = [[UIView alloc] initWithFrame:statusFrame];
    statusBar.backgroundColor = [UIColor whiteColor];
    [statusBar setAlpha:1.0f];
    [statusBar setOpaque:YES];
    [self.navigationController.view addSubview:statusBar];
}

它类似于Hot Licks的解决方案，但将子视图应用到navigationController。

- (void) viewDidLayoutSubviews {
    if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
        self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
        if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
            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;
    }
}

我把它的工作大小设置为自由形式

对于那些像我一样不愿意在UIViewController中嵌入UITableViewController的人来说，试试这个:

一个自定义的UITableViewController子类可以附加一个掩码视图到tableView的父视图。在viewDidAppear上添加蒙版，并在viewWillDisappear上删除蒙版。

private var statusBarMaskView: UIView!

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    if let superview = self.tableView.superview {
        self.statusBarMaskView = UIView(frame: CGRect.zero)
        superview.insertSubview(self.statusBarMaskView, aboveSubview: self.tableView)
        self.statusBarMaskView.backgroundColor = self.tableView.backgroundColor

        // using a nice constraint layout library to set the frame
        self.statusBarMaskView.pinTop(to: superview)
        self.statusBarMaskView.pinLeft(to: superview)
        self.statusBarMaskView.pinRight(to: superview)
        self.statusBarMaskView.addHeightConstraint(with: 22.0)
        ////
    }
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    self.statusBarMaskView.removeFromSuperview()
    self.statusBarMaskView = nil
}

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;
}
