iOS Multiple UIpickerView not showing Arrays - ios

Question

I have a hidden UIpickerView that should display a different Array depending on what button is pushed. The picker view shows up when the button is pushed but for some reason it doesn't show the Arrays in the picker view. I would be extremely grateful of any help!!!!
Here is the .m file:

#import <MessageUI/MessageUI.h>

#define kPICKERCOLUMN 1

CATEGORY_PICKER,
LOCATION_PICKER,
ORIGINATOR_PICKER,
DESTINATION_PICKER,
STATUS_PICKER
};
#define kPICKERCOLUMN 1
#define kPICKER_TAG 101
#interface ViewController ()
#end
#implementation ViewController
{
UIPickerView *picker;

}
