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];
