Answer 1

There are a few methods in NSString added by UIKit that can give you the dimensions of the string if it were to be drawn. The full reference is here. The methods you care about are probably these:

• sizeWithFont:
• sizeWithFont:constrainedToSize:
• sizeWithFont:constrainedToSize:lineBreakMode:
• sizeWithFont:forWidth:lineBreakMode:
• sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode:

Answer 2

-[NSString sizeWithFont:] is part of NSString(UIStringDrawing).
