Join an Array in Objective-C

I'm looking for a method of turning a NSMutableArray into a string. Is there anything on a par with this Ruby array method?

>> array1 = [1, 2, 3]
>> array1.join(',')
=> "1, 2, 3"

Cheers!

• Relevant discussion here.

• NSArray  *array1 = [NSArray arrayWithObjects:@"1", @"2", @"3", nil];
  NSString *joinedString = [array1 componentsJoinedByString:@","];
  

  componentsJoinedByString: will join the components in the array by the specified string and return a string representation of the array.

• The method you are looking for is componentsJoinedByString.

  NSArray  a = [NSArray arrayWithObjects:@"1", @"2", @"3", nil];
  NSString b = [a componentsJoinedByString:@","];
  NSLog(b); // Will output 1,2,3
  

• NSArray class reference:

  NSArray *pathArray = [NSArray arrayWithObjects:@"here",
      @"be", @"dragons", nil];
  NSLog(@"%@",
      [pathArray componentsJoinedByString:@" "]);
