How do I calculate the size of an NSString?

Question

I currently have an app that prints out a big text inside a TextView but I'm unsure how I can calculate what the height on the textView needs to be so it fits perfectly. Any help is greatly appreciated.

This is how my text would look like

I've resorted to putting the string into a dummy UILabel and telling the label to resize itself to fit. There are other functions that sound like they'd work, but they don't. — Hot Licks, Jul 08 '13 at 10:44

To "measure" text height you could use something like this:

-(CGFloat)measureText:(NSString*)text {  
    CGSize requiredSize = [text sizeWithFont:[UIFont systemFontOfSize:14]  constrainedToSize:CGSizeMake(220, CGFLOAT_MAX)];  
    return requiredSize.height;  
}

The "220" is the maximum width of the text view - change it for your case - and of course you could change the font type/size.

Also, have a look at NSString UIKit Additions Reference for more information.
