Question

I am currently drawing text on string, using drawInRect, restricted to a size using CGRectSize. It is also centred.

[text drawInRect:CGRectMake(0,0,nWidth,nHeight) withFont:font lineBreakMode:UILineBreakModeWordWrap alignment:UITextAlignmentCenter];

What I need to find out is the size and offset of the actual drawn text.
Because it is centred, there is a very good chance that there is an X offset before text is drawn.

I’ve seen the command boundingRectWithSize but I think it may not be supported on IOS?

Answer 1

Get the size of the text,

CGSize size = [text sizeWithFont:font constrainedToSize:CGRectMake(0,0,nWidth,nHeight) lineBreakMode: UILineBreakModeWordWrap];

(See documentation)

Then, since it is centered, the bounds will be

CGRect bounds = CGRectMake((nWidth - size.width)/2, ..., size.width, size.height);
