IOS - Get height NSString

Question

How i can get height absolutely of NSString, because I'm trying to do the following:

NSString *text = "Hello word, i'm a programer";
CGSize maximumSize = CGSizeMake(300, 9999);

UIFont *myFont = [UIFont fontWithName:@"Helvetica" size:12];

CGSize myStringSize = [text sizeWithFont:myFont
                       constrainedToSize:maximumSize
                           lineBreakMode:NSLineBreakByWordWrapping];

NSLog(@"myStringSize %f",myStringSize.height);

"Fix my code" issues have no future use when there are numerous working examples. — Marcus Adams, Jul 26 '13 at 19:17
You're missing the "@" before the text, and secondly, what do you mean by "not ok"? Does it crash? Does it produce a wrong result? In that case, what is the result and what did you expect? — Can, Jul 27 '13 at 02:55
@Can: "not ok" is mean :The result return height in my NSLog above not true — BlueSky, Jul 27 '13 at 03:38
@BlueSky So "not ok" means "not true", gotcha. Buddy, you need to tell us the output of the NSLog, and how much did you expect it should be. I don't know what "not true" or "not ok" means to you. — Can, Jul 27 '13 at 03:43
@Can: thank you for enthusiasm, in my code I showed NSLOG and result return is "eg: 310", this is number height of NSString, of course number's incorrect, actualy it only "90" or "120", I use to manual canculate. — BlueSky, Jul 27 '13 at 04:20

Use this:

CGSize maximumSize = CGSizeMake(300, 9999);
NSString *myString = @"This is a long string which wraps";
UIFont *myFont = [UIFont fontWithName:@"Helvetica" size:14];
CGSize myStringSize = [myString sizeWithFont:myFont 
                       constrainedToSize:maximumSize 
                           lineBreakMode:self.myLabel.lineBreakMode];

Your code isn't working because you are not using an NSString!
