问题描述

我有一个由UIImageView组成的viewController，它填充了整个视图以及位于视图中心的两个textField.所有这些都位于ScrollView内部. 我使用情节提要，并且禁用了自动布局. 当我单击textField从而打开键盘时，我希望将滚动条直接移到textField上.我该怎么办?

I've a viewController composed by an UIImageView that fills the whole view and two textField located at the center of the view. All this is located inside a ScrollView. I use Storyboard and I disabled the autolayout. When I click on a textField, and thus opens the keyboard, I'd like that the scroll is displaced directly on textField. How can I do that?

推荐答案

考虑将您的TextField出口命名为txtField，然后实施

Consider that your TextField outlet is named txtField then implement UITextField Delegate using

txtField.delegate = self;

考虑到您的ScrollView插座被命名为scrollView.实现Textfield委托方法:

Considering that your ScrollView outlet is named scrollView. Implement the Textfield Delegate method:

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    NSLog(@"%@",NSStringFromCGRect(textField.frame));
    [scrollView scrollRectToVisible:textField.frame animated:YES];
}

希望这会有所帮助.
