从iOS7开始，在我的UITableView顶部有额外的空间它有一个UITableViewStyleGrouped样式。
这里有一个例子:
tableview从第一个箭头开始，有35个像素的无法解释的填充，然后绿色的头是一个由viewForHeaderInSection返回的UIView(其中section为0)。
有人能解释一下这个35像素的数量是从哪里来的吗?我如何才能在不切换到UITableViewStylePlain的情况下摆脱它?
更新(回答):
在iOS 11及更高版本中:
tableView.contentInsetAdjustmentBehavior = .never
当前回答
当使用分组TableView时，使用这个来避免viewWillAppear中的边界切割
self.tableView.contentInset = UIEdgeInsetsMake(-35, 0, 0, 0);
其他回答
self.automaticallyAdjustsScrollViewInsets = NO;
试试吧，你能搞定的!
故事板:
确保你的UITableView top约束没有说“Under top layout guide”。相反，它应该说“顶部空间:Superview”(Superview.Top)。
当然，在包含UITableView的UIViewController中，取消勾选“调整滚动视图Insets”。
只需将你的tableview(或使它开始)固定在视图的绝对顶部。多余的空间正好是导航条的高度。
None of the previous answers worked for me. What did end up working for my situation (which was seeing that padding after dynamically adding a header to my Table View) was selecting the Navigation Bar from the Document Outline and rechecking the Translucent box (contrary to some answers that were saying to force it to be translucent). I had previously unchecked it because it had made my red look a little orange, but I could not try the solution of reordering the elements in the scene since the Table View was the only element in this scene. This solution works as long as you are okay with the Navigation Bar's color having a translucent layer over it. Hope this helps :)
set
override func viewDidLoad() {
self.tableView.delegate = self
self.tableView.dataSource = self
}
