Delete all objects from NSMutableArray starting from index 3

Question

I have NSMutableArray named dishArray. I have total 15 objects in this array.

I only want first three objects in array and delete the rest array.

Is there any way (other then looping) to delete?

I know using loop I can achieve it, but I am looking for alternate way. May be like deleteArray From: To:

NSMutableArray *array = ...;
if ([array count] > 3) {
    [array removeObjectsInRange:NSMakeRange(3, [array count] - 3)];
}

Use the function removeObjectsInRange.

 if ([yourArray count] > 3)
 [yourArray removeObjectsInRange:NSMakeRange(3, [yourArray count] - 3)];

Try with following code:

 if ([wholeArray count] > 3)    
    NSArray* finalArray = [wholeArray removeObjectsInRange(2, wholeArray.count-3)];

    NSRange r;
    r.location = 0; // start position
    r.length = 3;  // end position

    [arr removeObjectsInRange:r];
