Get the NSString height

Question

I have an NSString, and I want to know its height to create an appropriate UILabel.

Doing this

NSString *string = @"this is an example"; 
CGSize size = [string sizeWithFont:[UIFont systemFontOfSize:10.0f] 
                          forWidth:353.0 
                     lineBreakMode:UILineBreakModeWordWrap];
float height = size.height;

height is now 13.0. If I use this string

NSString *string = @"this is an example this is an example this is an example 
                     this is an example this is an example this is an example 
                     this is an example this is an example this is an example 
                     this is an example this is an example this is an example 
                     this is an example this is an example this is an example 
                     this is an example ";

height is always 13.0 (and with 353 as width, that's impossible)... what am I doing wrong?

ADD:

size.width;

works fine... so it's like if the lineBreakMode is not correct... but it is, isn't it?
