表格视图在文本字段开始编辑iphone时滚动 [英] Table View scroll when text field begin editing iphone

问题描述

我在iphone应用程序中有表视图控制器。表视图有两个部分。第一部分有两行，第二部分有一行。第二部分有一个自定义表格视图单元格。

I have table view controller in iphone application. Table view has two sections. First section has two rows and second section has one row. Second section has a custom table view cell.

第二部分有一个文本字段，当文本字段开始编辑并弹出键盘时会隐藏该文本字段。我希望这个表格视图在键盘弹出时滚动。

Second section has a textfield which hides when text field begin editing and keyboard pops up. I want this table view to scroll when keyboard pops up.

我尝试了以下代码，我在不同的网站上遇到但是徒劳无功。

I tried the following code which I came across on different websites but in vain.

提前致谢。

-(void) textFieldDidBeginEditing:(UITextField *)textField {

    CGRect textFieldRect = [textField frame];
    [self.tableView scrollRectToVisible:textFieldRect animated:YES];
} 
                          atScrollPosition:UITableViewScrollPositionMiddle animated:YES];
}

-(void) textFieldDidBeginEditing:(UITextField *)textField {

    UITableViewCell *cell = (UITableViewCell*) [[textField superview] superview];
    [self.tableView scrollToRowAtIndexPath:[tableView indexPathForCell:cell] 
                          atScrollPosition:UITableViewScrollPositionMiddle animated:YES];
}

推荐答案

我遇到过这个问题静态Cell TVC。覆盖 viewWillAppear 并且不调用其Super时会出现问题。所以，如果你这样做，请务必致电

I have run into this on Static Cell TVC's. There is an issue when overriding viewWillAppear and NOT calling its Super. So if you are doing that, make sure to call

[super viewWillAppear:animated];

位于顶部viewWillAppear
