Initialize arrays of NSString in objective-c

问题

What's the easiest / fastest way to initialize an array of NSStrings in objective-c ?

回答1:

NSArray *array = [NSArray arrayWithObjects:@"String1",@"String2",@"String3",nil];

回答2:

• 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" ];
  

  More info here: What are the details of "Objective-C Literals" mentioned in the Xcode 4.4 release notes?

回答3:

NSArray *array = @[@"foo",@"bar"];

回答4:

NSString *stringArray[2] = {@"1", @"2"};
