Join an Array in Objective-C

Question

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]

Answer 1

The method you are looking for is componentsJoinedByString.

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