How do I add multiple components to a PickerView?

Question

It may be a simple question but how do I add multiple components to a UIPickerView? I use NSMutableArray to populate one component but I dont know how to populate the others

Answer 1

You need to set the datasource and use

– numberOfComponentsInPickerView:
– pickerView:numberOfRowsInComponent:

set its delegate and use:

– pickerView:didSelectRow:inComponent:

to change your label when a certain row in a certain component is selected. Very likely to UITableViewDelegate and Datasource

and also taking a glance to documentation helps :)
