Objective c 更改联系人的图像时

我试图在

peoplePickerNavigationController

中更改所选联系人的图像，但当我选择联系人时，不会更改图像，也不会显示错误

嗯，据我所知，没关系！少了什么

代码如下：

ABAddressBookRef aBook = ABAddressBookCreate();

UIImage *img = [UIImage imageNamed:@"90x90.png"];
NSData *dataRef = UIImagePNGRepresentation(img);
CFDataRef cfdata = CFDataCreate(NULL, [dataRef bytes], [dataRef length]);
CFErrorRef error;

if(ABPersonRemoveImageData(person, &error)){
    NSLog(@"OK");
}
if(ABAddressBookSave(aBook, &error)){
    NSLog(@"OK");
}

if(ABPersonSetImageData(person, cfdata, &error)){
    NSLog(@"OK");
}
if(ABAddressBookSave(aBook, &error)){
    NSLog(@"OK");
}

CFRelease(cfdata);

[self dismissModalViewControllerAnimated:YES];
return NO;

请记住，上述代码在BOOL中：

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

谢谢

设法解决了，对于将来有相同问题的人，只需使用

ABRecordGetRecordID

和

ABAddressBookGetPersonWithRecordID

并遵循以下代码即可：

ABAddressBookRef aBook = ABAddressBookCreate();

NSNumber *recordId = [NSNumber numberWithInteger:ABRecordGetRecordID(person)];
ABRecordRef pID = ABAddressBookGetPersonWithRecordID(aBook,recordId.integerValue);

UIImage *img = [UIImage imageNamed:@"90x90.png"];
NSData *dataRef = UIImagePNGRepresentation(img);
CFDataRef cfdata = CFDataCreate(NULL, [dataRef bytes], [dataRef length]);
CFErrorRef error;

ABPersonRemoveImageData(pID, &error);
ABAddressBookSave(aBook, &error);

ABPersonSetImageData(pID, cfdata, &error);
ABAddressBookSave(aBook, &error);

CFRelease(cfdata);

[self dismissModalViewControllerAnimated:YES];
return NO;

谢谢
