(): Where the return type goes. Use void if you don’t want to return anything!
Next is the name of the method. Use camelCase and make the name easy to remember an understand.
If your method needs parameters, now is the time! The first parameter come right after the name of the function like this :(type)parameterName. All the other parameters are done this way parameterLabel:(type)parameterName
What does your method do? Put it all here, in the curly braces {}!
