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。

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);
}

我发现最简单的方法,尤其是当你在标签栏中添加表格视图时,首先添加一个视图,然后在该视图中添加表格视图。这将为您提供您正在寻找的最高边际指导。

这是用Swift写的 调整@lipka的回答:

tableView.contentInset = UIEdgeInsetsMake(20.0, 0.0, 0.0, 0.0)

我最终使用了一个额外的背景视图,添加在TableView之后,放在状态栏下:

    self.CoverView = [[UIView alloc]init];

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

    self.CoverView.frame = CGRectMake(0,0,self.view.bounds.size.width,20);
    }

    self.CoverView.backgroundColor = [UIColor whiteColor];
    self.TableView = [[UITableView alloc]initWithFrame:CGRectMake(0,
    self.CoverView.bounds.size.height,XXX, YYY)];
    [self.view addSubview:self.TableView];
    [self.view addSubview:self.CoverView];

它不是很漂亮,但它是一个相当简单的解决方案,如果你需要使用xib-less视图,同时适用于IOS6和IOS7

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。

override func viewDidLoad() {
 // your code

 if let nc = self.navigationController {
   yourView.frame.origin.y = nc.navigationBar.frame.origin.y + nc.navigationBar.frame.height
  }
}
