问题描述
我有一个弹出窗口，里面有：
I have a popover screen, with inside it :
- 一个标签，可能出现也可能不出现（标题）
- 一个搜索栏，可能出现也可能不出现
- 一个标签，可能出现也可能不出现，且高度可变（帮助标签）
- 滚动视图，可能出现也可能不出现，并且具有可变高度（关于下表的一些信息）
- 表格视图
- a label, that may or may not appear (title)
- a search bar, that may or may not appear
- a label, that may or may not appear, and has a variable height (help label)
- a scrollview, that may or may not appear, and has a variable height (some infos about the following table)
- a table view
为了呈现一些不错的东西，在 viewDidLoad 中，我移动各种框架以放置对象正确，没有未使用的空格混乱我的弹出窗口。此外，我然后调整表的大小（以占据最需要的位置），并通过 contentSizeInPopover 弹出窗口（以避免有一个近乎空的巨大弹出窗口）。所有调整大小似乎很好，但我有一个大问题：所有调整大小完成后，我的UITableView的一些单元格变得无法响应。一个或两个单元格，通常是第二个单元格，只有在我的外角点击时才会响应，但是单元格的其余部分完全忽略任何触摸。
In order to present something nice, in viewDidLoad, I move the various frames to place the objects correctly and not have unused spaces cluttering my popover. Besides, I then resize the table (to take the most place needed), and the popover via contentSizeInPopover (to avoid having a near-empty huge popover). All that resizing seems to work nicely, but I have one big problem : with all that resizing done, some cells of my UITableView become unresponsive. One or two cells, usually the second one, only respond if i tap in their outer corners, but the rest of the cell completely ignore any touches.
我试过了一切：全部移动到 viewWillAppear ，让autoresize完成它的工作（似乎也没有工作），但我每次都有这个问题。我发现如果我评论涉及更改表的 frame 或 contentSizeInPopover 中的行，问题停止了，但后来我的观点搞砸了，所以这不是一个修复。
I've tried everything : moving all to viewWillAppear, letting the autoresize do its job (doesn't seem to work either), but I still have this problem every time. I've found that if I comment the lines involved with changing the frame of the table, or the ones in contentSizeInPopover, the problem stops, but then my view is messed up, so this ins't a fix.
如果有人能给我一些东西摆脱这个烂摊子，那个会很棒。
If anyone could give me something to get out of this mess, that would be awesome.

推荐答案
自己找到答案：我在UITableView旁边使用自填UIScrollView的事实似乎是问题所在。一旦我用适当的UITableView替换了UIScrollView，问题就消失了。
Found the answer myself : the fact I was using a self-filled UIScrollView next to my UITableView seemed to be the problem. As soon as I replaced the UIScrollView by a proper UITableView, the problem disappeared.
