Fix iOS [sizeWithFont:constrainedToSize:lineBreakMode:] deprecation warning. Adjusts the label height (top align text).

gistfile1.m

// adjust the label height (top align text)
// old
CGSize labelSize = [model.name sizeWithFont:self.nameLabel.font
                          constrainedToSize:_maxNameLabelSize
                              lineBreakMode:self.nameLabel.lineBreakMode];
// new
CGSize labelSize = [model.name boundingRectWithSize:_maxNameLabelSize
                                            options:NSStringDrawingUsesLineFragmentOrigin
                                         attributes:@{NSFontAttributeName: self.nameLabel.font}
                                            context:nil].size;

// update label (won't compile, but you get it)
// self.nameLabel.frame.size.height = labelSize.height;

And how do you set the lineBreakMode?

NSMutableParagraphStyle * paragraphStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];
paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;

[model.name boundingRectWithSize:_maxNameLabelSize
                         options:NSStringDrawingUsesLineFragmentOrigin
                      attributes:@{NSFontAttributeName: self.nameLabel.font,
                                   NSParagraphStyleAttributeName:paragraphStyle}
                         context:nil].size;
