POWhy is UITextView contentInset/padding different on simulator vs device?

copied!<p>I'm debugging a strange text wrapping problem on my device that I have tracked down to some kind of modification in the <code>UITextView</code> contentInset value starting in XCode 4. </p> <p>Here is the sample code I am using to showcase this bug:</p> <pre><code>NSString *message = @"How are you doing?"; CGSize messageDimensions = [message sizeWithFont:[UIFont systemFontOfSize:15.0] constrainedToSize:CGSizeMake(self.view.frame.size.width,9999) lineBreakMode:UILineBreakModeWordWrap]; CGFloat xOffset = 20; CGFloat yOffset = 20; CGRect textViewFrame = CGRectMake(xOffset, yOffset, messageDimensions.width+16, messageDimensions.height+16); self.textView = [[[UITextView alloc] initWithFrame:textViewFrame] autorelease]; self.textView.font = [UIFont systemFontOfSize:15.0]; self.textView.text = message; self.textView.editable = NO; [self.view addSubview:self.textView]; </code></pre> <p>Attached are two screenshots running code on the iOS 5 simulator and on my iPhone 4. </p> <p>Here is the iPhone 4 running iOS5: </p> <p><img src="https://i.stack.imgur.com/EBKxW.png" alt="device"></p> <p>Here is the simulator running iOS5.0:</p> <p><img src="https://i.stack.imgur.com/O1Yxm.png" alt="simulator"></p> <p>As you can see, it is wrapping in one but not the other. In order to prevent wrapping on my iOS4 device I have to change this line:</p> <pre><code>CGRect textViewFrame = CGRectMake(xOffset, yOffset, messageDimensions.width+16, messageDimensions.height+16); </code></pre> <p>To have a padding of +17 not +16. </p> <p>Can anyone tell me if this is a known bug, and if the <code>UITextView</code> padding amount is a constant value somewhere in UIKit to which I can refer instead of hard-coding it? </p> <p>Thanks!</p>
