旋转时在uitableviewcell中自动调整uitextview

Question

我有一个非常简单的UITableView，它在左侧包含一个固定标签，然后在每个单元格中包含一个UITextField。当设备旋转时，我需要uitextfield来扩展和收缩它与单元格的宽度。我试过设置

autoresizesSubviews = YES; autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleRightMargin;

对于tableview，单元格和cell.contentView，它们似乎都没有影响textField。

当我将实际textField的autoresizingMask设置为flexibleWidth和FlexibleRightMargin时，无论它在什么方向，textField都会远离屏幕。

这是我创建textField并将其添加到单元格的代码：

    int marginBetweenCellAndScreenEdge;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    marginBetweenCellAndScreenEdge = 44;
} else {
    marginBetweenCellAndScreenEdge = 10;
}

float viewWidth = self.parentViewController.view.bounds.size.width;
int textFieldWidth = viewWidth - (2*marginBetweenCellAndScreenEdge) - 75 - 20;
NSLog(@"%d", textFieldWidth);

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(90, 12, textFieldWidth, 25)];
textField.clearsOnBeginEditing = NO;
[textField setDelegate:self];
textField.returnKeyType = UIReturnKeyDone;
textField.tag = kTextFieldTag;

textField.autoresizingMask = UIViewAutoresizingFlexibleWidth;


//make it so that the UITextField subview resigns the firstresponder (keyboard) when done editing
[textField addTarget:self action:@selector(textFieldDone:) forControlEvents:UIControlEventEditingDidEndOnExit];

[cell.contentView addSubview:textField];

任何帮助将不胜感激!!谢谢！
