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:


当前回答

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。

我有一个UITableView顶部的UISearchBar和以下工作;

self.tableView.contentInset = UIEdgeInsetsMake(20, 0, 0, 0);
self.tableView.contentOffset = CGPointMake(0, -20);

对于Xcode 7,取消导航栏的“半透明”复选标记对我来说很有效。

请注意:这适用于以下配置:

屏幕顶部没有导航栏(表视图满足状态栏) 表视图不可滚动

如果以上两个要求不满足,您的里程可能会有所不同。

最初的发布

我以编程方式创建了我的视图,这最终为我工作:

- (void) viewDidLayoutSubviews {
    // only works for iOS 7+
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        CGRect viewBounds = self.view.bounds;
        CGFloat topBarOffset = self.topLayoutGuide.length;

        // snaps the view under the status bar (iOS 6 style)
        viewBounds.origin.y = topBarOffset * -1;

        // shrink the bounds of your view to compensate for the offset
        viewBounds.size.height = viewBounds.size.height + (topBarOffset * -1);
        self.view.bounds = viewBounds;
    }
}

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
}

我不知道这有多合理,但我发现这个方案将ViewController的视图向下移动,并为状态栏提供了一个坚实的背景:

- (void)viewDidLoad {
    [super viewDidLoad];

    // Shove everything down if iOS 7 or later
    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.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 redColor];
        [self.view addSubview:statusBar];
    }

当然,将redColor替换为任何你想要的背景颜色。

您必须单独执行其中一个旋转来设置状态栏中字符/符号的颜色。我在plist中使用基于视图控制器的状态栏外观= NO和状态栏样式=不透明的黑色样式,来实现全局。

似乎工作,我很有兴趣听到任何错误或问题与它。
