UITableViewController和UITextFields的奇怪行为

I'm observing some strange behaviour when working with a UITableViewController and UITextFields in the cells.

在单元格中使用UITableViewController和UITextFields时，我观察到一些奇怪的行为。

The UITextFields delegate is set to the UITableViewController and when entering editing mode the tableview scrolls to the relevant cell, and does not obscure the input with the keyboard.

UITextFields委托设置为UITableViewController，当进入编辑模式时，tableview会滚动到相关单元格，并且不会使键盘模糊输入。

However, when I present another view controller using

但是，当我使用另一个视图控制器时

[self presentViewController:vc animated:TRUE  completion:^() {}];

And later dismiss it with

后来解雇了

[self dismissViewControllerAnimated:YES completion:^{}];

The table stops scrolling and resizing to fit the keyboard.

该表停止滚动和调整大小以适应键盘。

It does not seem to matter where I call the presentViewController method (in the cell, in the headers or in a toolbar)

在我调用presentViewController方法的位置（在单元格中，在标题中或在工具栏中）似乎并不重要

Any ideas?

有任何想法吗？

UPDATE 1:

更新1：

Delegate for my UITextField is set in - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath with cell.textField.delegate = self

我的UITextField的委托设置在 - （UITableViewCell *）tableView：（UITableView *）tableView cellForRowAtIndexPath：（NSIndexPath *）indexPath with cell.textField.delegate = self

I only override viewWillAppear:(BOOL)animated:

我只覆盖viewWillAppear：（BOOL）动画：

- (void) viewWillAppear:(BOOL)animated  {
    [super viewWillAppear:animated];
    [[GAI sharedInstance].defaultTracker sendView:@"Some view name"];
}

UPDATE 2

更新2

Manually calling

手动打电话

[self dismissViewControllerAnimated:YES completion:^{
        [self viewWillAppear:YES];
}];

Fixes it, but i'd still like some input to why this is necessary ?

修复它，但我仍然喜欢为什么这是必要的一些输入？

#1

Somewhere in the view hierarchy I had missed a call to [super viewWillAppear:].

在视图层次结构的某个地方，我错过了对[super viewWillAppear：]的调用。
