How to enlarge Picker View on iPhone?

Question

I add a PickerView to one of my views in an app, but its size is too small(in height). I find that I cannot drag to make it "longer". How to change its size then?

Answer 1

The only way is by adjusting the pickerView.frame.size.height, but you'll get some pretty bad visual artifacts.

I would think long and hard about attempting to circumvent the established design of this control. If you have so many items or your items are too big for this view, a UITableView is probably what you want to go with. It's far more customizable and can handle items/cells of all different shapes and sizes.
