I have a UITextView
included in a UITableViewCell
. The layout is correct when the views are initially displayed, but once I click in the UITextView
it automatically scrolls up a bit and the top half of the characters on the first line becomes invisible.
This image is when the UITextView
is not active:

And this one is when I clicked in the UITextView
to make it active:
UITextView active http://gerodt.homeip.net/uitextview-active.png
I do not the UITextView to scroll up at all, it should simple stay fixed. How can I achieve this? I already tried several settings in Interface Builder
, but no luck so far.
Any suggestions are appreciated.

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
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.
