您可以使用方法- (void)setContentOffset:(CGPoint)contentOffset animated:(BOOL)animated在UIScrollView中设置(void)setContentOffset:(CGPoint)contentOffset animated:(BOOL)animated ，这应该滚动到您给定的点的偏移量，您需要通过代码找出偏移量

Answer 3

I've written a pretty straightforward tutorial on doing this, it mimics as much as possible the behavior of Apple own applications, if it can be of any help:

Adjust UITextField hidden behind Keyboard with UIScrollView

Answer 4

Maybe you could set the text fields' delegates to self, and then adopt the UITextFielDelegate protocol for the class, and then in this method:

- (void)textFieldDidBeginEditing:(UITextField *)textField

Make the scroll view scroll down enough so that you can see the text field.. I don't know how to make the scrollview scroll down though.

Here is a free library for keyboard handling http://www.codeproject.com/Tips/509810/Keyboard-Handling-in-iPhone-Applications . You need write just one line of code:

[AutoScroller addAutoScrollTo:scrollView];

Dont confuse with name AutoScroller. Purpose is same what you asked.
