How to stop UITextView from scrolling up when entering it

Answer 1

This is how UITextView behaves according to Apple's engineer this is intended and UITextView is meant for text that are at least a few lines in height. There is no work around to this, use a UITextField instead or increase your UITextView to at least 3 lines in height.

Answer 2

UITextView is a subclass of UIScrollView, so it has a configurable contentInset property. Unfortunately, if you try to change contentInset on a UITextView instance, the bottom edge inset always gets reset to 32. I've run into this before with short UITextView frames and found this to be an issue. I suspect this is what is causing your problem, but you should check the contentInset of your textview in the debugger to be sure.

The workaround/solution is simple: subclass UITextView and override the contentInset method so that it always returns UIEdgeInsetZero. Try this:

//
// BCTextView
//
// UITextView seems to automatically be resetting the contentInset
// bottom margin to 32.0f, causing strange scroll behavior in our small
// textView.  Maybe there is a setting for this, but it seems like odd behavior.
// override contentInset to always be zero.
//
@interface BCZeroEdgeTextView : UITextView
@end

@implementation BCZeroEdgeTextView

- (UIEdgeInsets) contentInset { return UIEdgeInsetsZero; }

@end

Brian's answer to subclass the UITextView worked great for me! I'm so happy to have finally found a solution for a single line UITextView. (A UITextField in a table cell was causing strange problems for me when the view was popped off the nav bar.)

Answer 4

The subclass method works fine.

textView.contentInset = UIEdgeInsetsZero;

That doesn't seem to do anything.

I'd much rather NOT subclass... but how?
