you can remove duplicate data from your array like:

NSArray *cleanedArray = [[NSSet setWithArray:yourArray] allObjects];

---

Take another Array and insert distinct value in that, then use that array as your data source for the picker.

Try this before assigning it to picker-view.

for (int i=0; i<[array count]; i++)
        for (int j=i+1; j<[array count]; j++)
            if ( [[array objectAtIndex:i] isEqual:[array objectAtIndex:j]])
                [array removeObjectAtIndex:j];
