How to pass an array to my custom cell class - objective-c

Question

I have a TableView with my custom cell class where I have a pickerview.
I want to pass an array to populate pickerview with data. How to pass it. Is my approach correct?

Answer 1

You don't pass anything to a TableViewCell. Instead you have to implement
UITableViewDelegate
UITableViewDatasource
to populate the tableView. And
UIPickerViewDelegate
UIPickerViewDatasource
for the pickers.

Answer 2

I have included pickerview delegate and datasource within table cell and it works fine...
Passing the array is same as to any view.
//////////////ScrollCell.h
#interface ScrollCell : UITableViewCell <UIPickerViewDataSource, UIPickerViewDelegate>{
UILabel *textlabel;
UIPickerView *pickerview;
NSString *textfieldValue;
NSString *scrollerValue;
NSArray *scrollerData;
}
#property (nonatomic,retain)UILabel *textlabel;
#property (nonatomic,retain)UIPickerView *pickerview;
#property (nonatomic,retain)NSArray *scrollerData;
#property (nonatomic,retain)NSString *textfieldValue;
#property (nonatomic,retain)NSString *scrollerValue;
-(NSString *)getTextfiledValue;
-(NSString *)getScrollerValue;
-(void)setScrollerData:(NSArray *)array;
