Question

调用PeoplePicker并从“联系人”中选择一个条目后，我似乎无法在我的视图中显示所选的联系人信息。按照Apple的iOS地址簿编程指南，我以模态方式显示人物选择器并进行选择。 Apple的代码示例将信息显示在UILabels中，因为我还允许用户手动将信息输入到同一视图控制器的文本字段中，需要在UITextFields中显示信息。我已经通过打印到控制台证明所选数据在目标UITextField（名为“contactName”）中结束。问题是，所选数据不会显示在视图中。当用户手动输入时，没有问题。我无法弄清楚如何将数据从通讯簿传输到视图控制器中的UITextFields。

我已经尝试了几天，但无法解决这个问题。我可能忽略了一些非常基本的东西。我是新手，所以任何帮助都会受到赞赏。

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
{

   // NSString* name = (NSString *)ABRecordCopyValue(person,kABPersonFirstNameProperty);
    NSString *name = [NSString stringWithFormat:@"%@ %@",ABRecordCopyValue(person,kABPersonFirstNameProperty), ABRecordCopyValue(person,kABPersonLastNameProperty)];

    self.contactName.text = name;   // 11/17/11

    NSLog(@"%@", name);
    // [name release];  Commenting out this code prevents the app from freezing when a name is selected from the picker.  11/25/11
    NSLog(@"%@",self.contactName.text);                // 11/17/11

    // 11/16/11 add additional contact info here

    [self dismissModalViewControllerAnimated:YES];
    return NO;
}

-(IBAction)addToAddressbook:(id)sender{

    NSString *lname=@"lastname";
    NSArray *arrayAdd=[[NSArray alloc]initWithObjects:@"street Name",@"city Name",@"country code",@"zip",nil];

-(void) addContact:(NSString *)firstname:(NSString *)lastname:(NSArray *)arrayAddress:(UIImage *)currentImage
{
    ABAddressBookRef addressBook=ABAddressBookCreate();
    ABRecordRef person=ABPersonCreate();
    //set Image
    NSData * dataRef = UIImagePNGRepresentation(currentImage);
    ABPersonSetImageData(person, (CFDataRef)dataRef, nil);
    //set FirstName and LastName

    [email release];
}


- (void)unknownPersonViewController:(ABUnknownPersonViewController *) unknownCardViewController didResolveToPerson:(ABRecordRef)person
{
    [objABPersonViewController dismissModalViewControllerAnimated:YES];
}

从iOS 6开始，不推荐使用[self dismissModalViewControllerAnimated]。如果你试试这个，你的代码就可以了。

[self dismissViewControllerAnimated:YES completion:^(void) {
NSString *name = [NSString stringWithFormat:@"%@", ABRecordCopyValue(person, kABPersonFirstNameProperty)];
contactName.text=name;
}];

使用从iPhone联系人中选择的联系信息更新UITextField
