我正在尝试使用选定的联系信息填充“表格视图单元格”。我旁边有一个“Stepper + & -”来添加选定的联系人并将其删除..

我需要知道如何让'+'打开框架......

在接口文件中我写了如下:

#import <UIKit/UIKit.h>
#import <AddressBookUI/AddressBookUI.h>

@interface APPNAME : UIViewController

@end

@interface ViewController : UIViewController <ABPeoplePickerNavigationControllerDelegate>

@property (weak, nonatomic) IBOutlet UILabel *phoneNumber;

- (IBAction)showPicker:(id)sender;

@end

在实现文件中,我写了如下:

@implementation ViewController

- (IBAction)showPicker:(id)sender
{
ABPeoplePickerNavigationController *picker =
[[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;

[self presentModalViewController:picker animated:YES];
}

@end

但它不起作用....有什么建议吗?
