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:

适用于swift 3 - In viewDidLoad();

let statusBarHeight = UIApplication.shared.statusBarFrame.height

let insets = UIEdgeInsets(top: statusBarHeight, left: 0, bottom: 0, right: 0)
tableView.contentInset = insets
tableView.scrollIndicatorInsets = insets

这段代码: 1. 获取状态栏的高度 2. 为表视图的顶部提供一个与状态栏高度相等的内容插入。 3.为滚动指示器提供相同的插入,因此它出现在状态栏的下方。

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
}

如果你用编程的方式做事情,并且使用一个没有UINavigationController的UITableViewController,你最好的选择是在viewDidLoad中做以下事情:

斯威夫特3

self.tableView.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 0, right: 0)

早些时候,迅速

self.tableView.contentInset = UIEdgeInsetsMake(20.0f, 0.0f, 0.0f, 0.0f);

UITableViewController仍然会滚动到状态栏后面,但当滚动到顶部时,不会在状态栏下面。

下面的解决方案在代码中工作得很好,不需要使用神奇的常量,并解释了用户改变大小类,例如通过旋转或ipad上的并排应用程序:

- (void)traitCollectionDidChange:(UITraitCollection *)previousTraitCollection {
    [super traitCollectionDidChange:previousTraitCollection];
    // Fix up content offset to ensure the tableview isn't underlapping the status bar.
    self.tableView.contentInset = UIEdgeInsetsMake(self.topLayoutGuide.length, 0.0, 0.0, 0.0);
}

这将修复一个UITableViewController(没有任何神奇的数字)。我唯一不能让它修复的是如果你在打电话,在这种情况下,tableView的顶部被下推太多。如果有人知道如何解决这个问题,请告诉我们。

class MyTableViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()    
        configureTableViewTop()
    }

    override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
        super.viewWillTransitionToSize(size, withTransitionCoordinator: coordinator)
        coordinator.animateAlongsideTransition({ (context) -> Void in
            }, completion: { (context) -> Void in
                self.configureTableViewTop()
        })
    }

    func configureTableViewTop() { 
        tableView.contentInset.top = UIApplication.sharedApplication().statusBarFrame.height
    }
}

在你的故事板上选择UIViewController,取消选中顶部栏下的扩展边。 为我工作。 : )
