POScrolling UITextView programmatically

copied!<p>I'm implementing some simple text chatting capabilities in my app and I'm having issues with scrolling the <code>UITextView</code> programmatically. I'm using a <code>UITextView</code> created in Interface Builder that appends a new line and some text to the preexisting text. When the new text is added it should scroll to the bottom.</p> <p>I built a test application to nail down the concept before adding it to my app. The text in the <code>UITextView</code> updates with the text from a <code>UITextField</code>, however no scrolling occurs.</p> <pre><code>- (IBAction)enteredText { CGPoint currentPosition = [textWindow contentOffset]; [textWindow setText:[NSString stringWithFormat:@"%@\n%@", textWindow.text, textInput.text]]; [textWindow setContentOffset:currentPosition animated:NO]; [textWindow scrollRangeToVisible:NSMakeRange([textWindow.text length], 0)]; [textInput setText:@""]; [textInput becomeFirstResponder]; </code></pre> <p>}</p> <p>I remember implementing a very similar feature in another application I developed a while ago andfrom what I remember the code is similar. The only difference is that the earlier application was for iPhone OS 2 but this one is for 3.0. I read in some forums that the 3.0 beta had some issues with scrolling when the <code>UITextView</code> was created in Interface Builder. I checked the <a href="http://developer.apple.com/iphone/library/releasenotes/General/RN-iPhoneSDK-3/index.html" rel="nofollow noreferrer">current release notes</a> and I didn't see anything indicating that.</p> <p><strong>Edit:</strong> The IB action is called because text is updated in the UITextView. And "Cancellable Content Touches" is checked.</p> <p><strong>Edit:</strong> Confirmed that the same code works on 2.2.1 but not 3.0</p>
