I think that using - (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view as I have advised you in the chat room won't help you achieve this UI.

I think that you are better use a UITableView with no separators between cells and place an image above the table so that it will look like a picker.

The problem using a regular UIPicker here is that you want the selected row to move.
In the picker the selected row is the one that is located in the center...

You should add custom view in picker control using below default method :

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view

{

}
