The bottom line is that I'm trying to reproduce the UI that iMessage has. For the Label: The special padding of that type of text made me create a custom UILabel. Here's the code under drawTextInRect:
[super drawTextInRect:UIEdgeInsetsInsetRect(rect, UIEdgeInsetsMake(0, 15.0, 5.0, 15.0))];
No mystery for now.
The problem comes when my cell (that contain that label has to calculate height). The Label gets a rounding effect on the label like so:
cell.message.layer.cornerRadius = 18;
[cell.message sizeToFit];
Apparently I can't get the proper height and width of that label. I'm using sizeToFit and then I mesure the possible sizes with "sizeWithFont:" (deprecated in iOS 7) and "boundingRectWithSize:". The only way the text can show properly is adding manually an undetermined amount of size to height and width once the calculations are made.
The best I can get then is a screen that may look good but still has some problems and not draws properly the texts.
The link has a screen of some of the screens not showing properly.
