How to Initialize arrays of NSString?

Question

What's the easiest / fastest way to initialize an array of NSStrings in Objective C?

Answer 1

• C way:

  NSString *s1, *s2;
  NSString *cArray[]={s1, s2};
  

  The size of the cArray is 2, defined by the compiler.

• NSArray (Objective-C) way:

  NSArray *objCArray = [NSArray arrayWithObjects:@"1", @"2", nil];
  

• If you are using XCode4 (LLVM4.0 compiler), now you can use NSArray literals:

  NSArray *array = @[ @"1", @"2" ];
