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。

chappjc的答案在使用xib时工作得很好。

当以编程方式创建TableViewControllers时,我发现最干净的解决方案是将UITableViewController实例包装在另一个UIViewController中,并相应地设置约束。

下面就是:

UIViewController *containerLeftViewController = [[UIViewController alloc] init];
UITableViewController *tableViewController = [[UITableViewController alloc] init];

containerLeftViewController.view.backgroundColor = [UIColor redColor];

hostsAndMoreTableViewController.view.translatesAutoresizingMaskIntoConstraints = NO;
[containerLeftViewController.view addSubview:tableViewController.view];

[containerLeftViewController addChildViewController:tableViewController];
[tableViewController didMoveToParentViewController:containerLeftViewController];

NSDictionary * viewsDict = @{ @"tableView": tableViewController.view ,
                              @"topGuide": containerLeftViewController.topLayoutGuide,
                              @"bottomGuide": containerLeftViewController.bottomLayoutGuide,
                              };
[containerLeftViewController.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[tableView]|"
                                                                                         options:0
                                                                                         metrics:nil
                                                                                           views:viewsDict]];
[containerLeftViewController.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[topGuide][tableView][bottomGuide]"
                                                                                         options:0
                                                                                         metrics:nil
                                                                                           views:viewsDict]];

其他回答

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。

我把它的工作大小设置为自由形式

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。
