带有ios 7和ios 8的人员选择器[重复]答案

【问题标题】：People Picker with ios 7, and ios 8 [duplicate]带有ios 7和ios 8的人员选择器[重复]
【发布时间】：2014-09-18 00:51:10
【问题描述】：

我有人员选择器在 ios 7 上工作，我正在尝试添加对 ios 8 的兼容性。我已将这两种方法添加到一个中，但我收到一个错误，上面写着预期的标识符或 '(' 之前的左括号NSString *contactName。任何建议都会很棒！

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {
    [self peoplePickerNavigationController:peoplePicker shouldContinueAfterSelectingPerson:person property:property identifier:identifier];


    NSString *contactName = CFBridgingRelease(ABRecordCopyCompositeName(person));
    self.nameField.text = [NSString stringWithFormat:@"%@", contactName ? contactName : @"No Name"];


    ABMultiValueRef phoneRecord = ABRecordCopyValue(person, kABPersonPhoneProperty);
    CFStringRef phoneNumber = ABMultiValueCopyValueAtIndex(phoneRecord, 0);
    self.phoneField.text = (__bridge_transfer NSString *)phoneNumber;
    CFRelease(phoneRecord);


    ABMultiValueRef email = ABRecordCopyValue(person, kABPersonEmailProperty);
    CFStringRef emailField = ABMultiValueCopyValueAtIndex(email, 0);
    self.emailField.text = (__bridge_transfer NSString *)emailField;
    CFRelease(email);

    CFDataRef  photo = ABPersonCopyImageData(person);
    UIImage* image = [UIImage imageWithData:(__bridge NSData*)photo];
    if(photo)
        CFRelease(photo);
    if(image)
        self.myImageView.image = image;
    [self dismissViewControllerAnimated:YES completion:nil];
    return NO;
}

-(BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker
     shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property
                             identifier:(ABMultiValueIdentifier)identifier
{
    [self dismissViewControllerAnimated:YES completion:nil];
    return NO; }

【问题讨论】：

我要做的就是实现旧的委托方法和新的委托方法。将自动调用正确的。
谢谢！我认为这是一种更好的方法
我已经更新了我的代码 sn-p，它抛出了一个错误关于如何解决这个问题的任何想法？
在 peoplePickerNavigationController:didSelectPerson: 方法之后有一个不匹配的 "} {"

【解决方案1】：

对于任何可能感兴趣的人，这是我的工作代码，适用于 ios 7 和 ios 8

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {
        [self peoplePickerNavigationController:peoplePicker shouldContinueAfterSelectingPerson:person property:property identifier:identifier];


        NSString *contactName = CFBridgingRelease(ABRecordCopyCompositeName(person));
        self.nameField.text = [NSString stringWithFormat:@"%@", contactName ? contactName : @"No Name"];


        ABMultiValueRef phoneRecord = ABRecordCopyValue(person, kABPersonPhoneProperty);
        CFStringRef phoneNumber = ABMultiValueCopyValueAtIndex(phoneRecord, 0);
        self.phoneField.text = (__bridge_transfer NSString *)phoneNumber;
        CFRelease(phoneRecord);


        ABMultiValueRef email = ABRecordCopyValue(person, kABPersonEmailProperty);
        CFStringRef emailField = ABMultiValueCopyValueAtIndex(email, 0);
        self.emailField.text = (__bridge_transfer NSString *)emailField;
        CFRelease(email);

        CFDataRef  photo = ABPersonCopyImageData(person);
        UIImage* image = [UIImage imageWithData:(__bridge NSData*)photo];
        if(photo)
            CFRelease(photo);
        if(image)
            self.myImageView.image = image;
        [self dismissViewControllerAnimated:YES completion:nil];
        return NO;
    }



       -(BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker
             shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property
                                     identifier:(ABMultiValueIdentifier)identifier
        {
            [self dismissViewControllerAnimated:YES completion:nil];
            return NO; }

谢谢！！这对我有用:)

【解决方案2】：

当代理方法的签名随着新的 iOS 版本更新时，旧的会保留一段时间。答案是： 实现新旧方法，会自动调用正确的方法。
