联系人设置地址簿中的图像似乎不工作

Question

我试图用下面的代码设定的接触图像。我没有看到任何错误，并且图像不会被保存在地址簿中的联系人条目。请帮忙！我必须错做一些...

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
{
[abcontroller setDisplayedPerson:person];

UIImage *im = [UIImage imageNamed:@"image1.jpg"];
NSData *dataRef = UIImagePNGRepresentation(im);
CFErrorRef error;
ABAddressBookRef addressBook = ABAddressBookCreate(); 

NSLog(@"Error:",error);
    if (ABPersonSetImageData(person, (CFDataRef)dataRef, &error))
    {
        NSLog(@"Set contact photo %@", error);
        if (ABAddressBookHasUnsavedChanges(addressBook))
        {
            NSLog(@"Changes made to address book");
        }
        else {
            NSLog(@"No changes made to address book");
        }

        if (ABAddressBookSave(addressBook, &error))
        {
            NSLog(@"Saved");

        }
        else {
            NSLog(@"Not saved");
        }


    }
    else {
        NSLog(@"Error saving contact photo %@", error);
    }
ABAddressBookSave(addressBook, &error);

[self dismissModalViewControllerAnimated:YES];    

return NO;
}

下面是我的输出日志：

2010-01-17 21:58:35.465 Error:
2010-01-17 21:58:35.504 Set contact photo <ABPeoplePickerNavigationController: 0x19e9b0>
2010-01-17 21:58:43.497 No changes made to address book
2010-01-17 21:58:44.724 Saved

我不知道为什么错误对象被记录为的ABPeoplePickerNavigationController对象？

Answer 1

关于我不知道为什么错误对象被记录为的ABPeoplePickerNavigationController对象的 - 因为你没有正确初始化这里的error：

CFErrorRef error;

分配nil这里，否则会具有随机（或更确切地说，一些先前的存储器）的值，顺便指向一个ABPeoplePickerNavigationController对象。

关于优点：你确定的参考person你传递给你的方法是在地址簿中的上下文中有效？我会首先尝试使用的功能，如ABAddressBookGetPersonWithRecordID，而不是通过周围和ABPersonRefs希望他们的有效期为不同的地址簿中的引用。

Answer 2

所有这些答案没有工作。 您应该简单地改变你的代码行从：

ABAddressBookRef addressBook = ABAddressBookCreate(); 

为：

ABAddressBookRef addressBook = [peoplePicker addressBook];

这样你得到的，参照“地址簿”，“人”属于。

Answer 3

我也尝试使用设置图像（照片）当前选中的人，但它显示按摩保存成功，但实际它没有作用！

的挖掘出的代码和由苹果SDK提供的文件后，我有一些使用以下溶液。

请检查出下面的代码。其真正的工作对我很好，也希望给你。

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
{
    @try {
        CFErrorRef cfError = nil;

        if (ABPersonHasImageData(person)) {
            NSLog(@"%s has an image", _cmd);

            //theAlert = [[UIAlertView alloc] initWithTitle:@"Contact already has an image" message:@"Are you sure you want to overwrite it?" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Overwrite"];
            //[theAlert show];
            //[theAlert release];
            //Note: We do not yet handle the answer to this question
        }

        // Just a sanity check

        if ((nil == [imageView image])
            || (nil == UIImagePNGRepresentation([imageView image]))) {
            NSLog(@"%s NIL STUFF", _cmd);
        }

        // Not sure I even need to create and save an address book
        // Cf. https://devforums.apple.com/message/27512#27512
        ABAddressBookRef libroDirec = ABAddressBookCreate();
        ABPersonSetImageData(person, (CFDataRef) (UIImageJPEGRepresentation([imageView image], 1.0f)), &cfError);
        ABAddressBookAddRecord(libroDirec, person, &cfError);
        if (ABAddressBookSave(libroDirec, nil)) {
            NSLog(@"%s saved successfuly", _cmd);
        } else {
            NSLog(@"%s something bad happen while saving", _cmd);
        }
        CFRelease(libroDirec);
    }
    @catch (NSException * e) {

    }
    @finally {

    }
    // TODO: release peoplePicker (and refactor code to not have it global)
    [self dismissModalViewControllerAnimated:YES];

    return NO;

}

我检查你的代码，这是行不通的，因为它应该。所以，我提出2度的变化。

ABAddressBookRef libroDirec = [peoplePicker addressBook];//don't create
        ABPersonSetImageData(person, (CFDataRef)UIImagePNGRepresentation(display.image), &cfError);
        ABAddressBookAddRecord(libroDirec, person, &cfError);

        if (ABAddressBookSave(libroDirec, nil)) {
            NSLog(@"\n%s saved successfuly", _cmd);
        } else {
            NSLog(@"\n%s something bad happen while saving", _cmd);
        }
        //CFRelease(libroDirec);

现在它的工作原理，因为它应该。
