Answer 2

我在表格单元格中包含了pickerview委托和数据源，它工作得很好...... 传递数组与任何视图相同。

//////////////ScrollCell.h

@interface ScrollCell : UITableViewCell <UIPickerViewDataSource, UIPickerViewDelegate>{
    UILabel *textlabel;
    UIPickerView *pickerview;

    NSString *textfieldValue;

    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;
@end
