Independent Double picker

I have double picker one picker for开发者_Python百科 suit (heart, diamond etc) of a card and the other the value of the card (king, ten, two etc). What I want to know how do I eliminate a value from the card picker once it was already selected so it cant be chosen again?

Keep your UIPickerView's data stored in an NSMutableArray. Then, when the user makes his choices, remove those objects from the data source array, and call

[self.myPickerView reloadAllComponents];

This will only work, of course, if you're not hardcoding the value for numberOfRowsInComponent:, but doing something like

- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component {
    return [dataArray count];
}
