Help with Objective-C variable declaration syntax

Question

Is there a difference between these two declarations? Is one better practice?

• NSString* hello = @"HelloWorld";
• NSString *hello = @"HelloWorld";

Thanks--

Answer 1

There is absolutely no difference, although the second one I find is more popular amongst Objective-C developers.

Answer 2

dreamlax's answer is correct but I would like to make the things more clear, the compiler strips whitespaces, both examples will be converted to NSString*hello=@"HelloWorld"; so there is no difference at all, use the one you feel more comfortable with. I prefer the second one, because its more clear (I read all declarations from right to left):

NSString *hello = @"HelloWorld"; ^ ^ ^ 3 2 1

1 => We have string value 2 => Pointer variable pointing to the address in memory where our object value is stored 3 => Object is of type NSString
