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:
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]];
