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!

[`NSArray` class reference][nsarray]:

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

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

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