First you need to work out the size of the text to fit in the area

CGSize size = [string sizeWithFont:[UIFont systemFontOfSize:14]
                     constrainedToSize:CGSizeMake(300, 900)
                         lineBreakMode:UILineBreakModeWordWrap];

Draw the text in that size

- (void)drawRect:(CGRect)rect {

    [self.text drawInRect:rect withFont:self.font lineBreakMode:UILineBreakModeWordWrap|UILineBreakModeTailTruncation alignment:UITextAlignmentLeft];

}

I used a stretchable UIImage to fit behind the text

UIImage *myImage = [[UIImage imageNamed:@"balloon.png"]  stretchableImageWithLeftCapWidth:23 topCapHeight:13];

Popped it in a UIImageView and set the frame to the be the same size as the text plus a bit of padding.

Hope this helps
