UIScrollView not scrolling in iOS7 with autolayout on

Question

I have a UIScrollView with a 6 textfields in it and a button inside of it. There is not enough content in the scrollView to make it scroll. But when the keyboard shows, I would like the scrollview to scroll so the user doesn't have to dismiss the keyboard in order to select another textfield that is hidden by the keyboard. I am using iOS7 and have autolayout enabled. Any suggestions? I am using storyboards and the only code I have is the following. reg.h file ``` interface registerViewController : UIViewController <UITextFieldDelegate, UIScrollViewDelegate> ```

Accepted Answer

In order to make a scrollview scrollable, the content size must be larger than the scrollview's frame so the scrollview has something to scroll to. Use setContentSize to adjust the content size:

```
[scrollview setContentSize:CGSizeMake(width, height)];
```

In this case, you should adjust the size to view.frame.width, view.frame.height + keyboard_height, then adjust the content offset once the keyboard appears:

```
[scrollview setContentOffset:CGPointMake(0, 0 - keyboard_height)];
```

If for some screwy, autolayout-related reason this still doesn't make the view scrollable, implement this setContentSize function in viewDidLayoutSubviews in order to override the autolayout:

```
- (void)viewDidLayoutSubviews {
     [scrollview setContentSize:CGSizeMake(width, height)];
}
```

EDIT: To reset the scrollview after dismissing the keyboard, reset the scrollview content size to the scrollview's frame and the offset to zero:

```
[scrollview setContentSize:CGSizeMake(scrollview.frame.size.width, scrollview.frame.size.height)];
[scrollview setContentOffset:CGPointZero];
```

P.S. To animate the content offset, use:

```
[scrollview setContentOffset:offsetSize animated:YES];
```
