objective-c - 从地址簿中获取图片的裁剪版本

Question

我使用以下代码从地址簿加载联系人图片:

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{

    UIImage *image = [UIImage imageWithData:(NSData *)ABPersonCopyImageData(person)];

    return NO;
}

但是，此代码返回存储的完整图像，而不是显示在地址簿等不同位置的裁剪版本。

NSData *imageData = (__bridge NSData*)ABPersonCopyImageDataWithFormat(person, kABPersonImageFormatThumbnail);
UIImage *image = [UIImage imageWithData:imageData];
