How to remove duplicates from NSMutableArray ?

Hi,

For removing or deleting duplicates from a NSMutableArray , use the following lines of code. It will simply check for duplicates elements and get it deleted or removed.


NSArray *tempArr= [urArray copy];

NSInteger idx = [tempArr count] - 1;

for (id object in [tempArr reverseObjectEnumerator]) {

     if ([urArray indexOfObject:object inRange:NSMakeRange(0, index)] !=NSNotFound) {

           [urArray removeObjectAtIndex:idx];
     }

idx--;

}
[tempArr release];
