copied!<p>Ok, based on my research and other answers, the problem was the <code>UITextView</code>'s content height and not the scrolling to a specific offset. Here is a solution that works the way it should work for iOS 7:</p> <p>First, you need to recreate the <code>UITextView</code> like this:</p> <pre><code> NSString *reqSysVer = @"7.0"; NSString *currSysVer = [[UIDevice currentDevice] systemVersion]; BOOL osVersionSupported = ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending); if (osVersionSupported) { NSLog(@"reset chatoutput"); CGRect outputFrame = self.chatOutput.frame; [chatOutput removeFromSuperview]; [chatOutput release]; chatOutput = nil; NSTextStorage* textStorage = [[NSTextStorage alloc] init]; NSLayoutManager* layoutManager = [NSLayoutManager new]; [textStorage addLayoutManager:layoutManager]; NSTextContainer *textContainer = [[NSTextContainer alloc] initWithSize:self.view.bounds.size]; [layoutManager addTextContainer:textContainer]; chatOutput = [[UITextView alloc] initWithFrame: outputFrame textContainer: textContainer]; // if using ARC, remove these 3 lines [textContainer release]; [layoutManager release]; [textStorage release]; [self.view addSubview: chatOutput]; } </code></pre> <p>Then, use this method to get the <code>UITextView</code> content height:</p> <pre><code>- (CGFloat)textViewHeightForAttributedText:(NSAttributedString*)text andWidth:(CGFloat)width { UITextView *calculationView = [[UITextView alloc] init]; [calculationView setAttributedText:text]; CGSize size = [calculationView sizeThatFits:CGSizeMake(width, FLT_MAX)]; NSLog(@"size: %f", size.height) ; return size.height; } </code></pre> <p>Now you can set the content offset:</p> <pre><code>CGPoint bottomOffset; bottomOffset = CGPointMake(0, [self textViewHeightForAttributedText: self.chatOutput.attributedText andWidth: self.chatOutput.frame.size.width] - self.chatOutput.frame.size.height); [self.chatOutput setContentOffset:bottomOffset animated:YES]; </code></pre> <p><strong>UPDATE</strong></p> <p>I've read this in the Apple Documentation for <code>NSAttributedString</code>: "The default font for NSAttributedString objects is Helvetica 12-point, which may differ from the default system font for the platform."</p> <p>In conclusion, if you use different fonts of different sizes, you have to set those to the <code>NSAttributeString</code> instance as well. Otherwise, the returned height won't correspond to your expectations. You may want to use something like this:</p> <pre><code> NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObject: [UIFont systemFontOfSize: 18.0] //or any other font or size forKey: NSFontAttributeName]; NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString: currentPost.postMessageText attributes: attrsDictionary]; frame.size.height = [self textViewHeightForAttributedText: attributedString andWidth: 280.0]; [attributedString release]; </code></pre>
