Can the size for -[NSString drawInRect:] be determined by the string's content?

I have a long string called theString in my code, which I'm passing to the drawRect: method to draw on screen.

    -(void)drawRect:(CGRect)rect
{
    [super drawRect:rect];
    [theString drawInRect:CGRectMake(0, 0, self.bounds.size.width, 200)]; 
}

As you can see, I can just set the width to the screen size, but the height has to be set manually, which is a problem when the strings being passed are of differing lengths. How do I automatically detect the height the frame needs to be? Also in the future I may be extending this to include an attributed string of differing font styles, so counting characters may not be a very good option.

you can do it by RTLabel. Download from this link RTLabel.h

RTLabel.m

use it by: set text to RTLabel object, it will handel HTML string also and get size of RTLabel object, it will be the size of your text.

What you can do is get the font that your text will have

UIFont *myFont = [UIFont fontWithName:@"SOME_NAME" size:16];

And then use NSString's method sizeWithFont:, like so:

CGSize theStringSize = [theString sizeWithFont:myFont];

Finally, set your string's width and height:

[theString drawInRect:CGRectMake(0, 0, theStringSize.width, theStringSize.height)];

Hope this helps!
