Using NSLog for debugging
debugging, nslog, objective-c, xcode
Solution
Try this piece of code:
NSString *digit = [[sender titlelabel] text];
NSLog(@"%@", digit);
The message means that you have incorrect syntax for using the `digit` variable. If you're not sending it any message - you don't need any brackets.
Problem
I have the following code snippet in my Xcode: ``` NSString *digit [[sender titlelabel] text]; NSLog([digit]); ``` I tried to build the application and am getting the following warning message for the line `NSLog([digit]);` ``` Warning: Format not a string literal and no format arguments ``` Can you advise me how I can resolve this warning message? What does the message actually mean?
