How to comment code: Xcode

Comment lines are used for separating some words or sentences from the executing code. In Xcode and cocos2d objective C platforms, you can comment lines as below:

•     Insert " // " infront of any line for single line comments 
•     Use "/* ....... */" for multi-line comments    

Example:
       
       1)   // This line is commented and
                 this second line is not commented.

      2)   /*
                By using this method, both the first line and
                the second line are commented
            */
