ABAddressBook内存泄漏

Question

我正在尝试与ABAddressBook进行交互，但在分析Xcode中的代码时，我有一些内存泄漏警告无法解决。我得到了“对象的潜在泄漏”和“存储到‘allContacts’中的对象的潜在泄漏”警告。

+ (void)addNewContact:(BusinessCard *)contact {
ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, nil);
ABRecordRef newContact = ABPersonCreate();
if (contact.firstName) ABRecordSetValue(newContact, kABPersonFirstNameProperty, (__bridge CFStringRef)contact.firstName, nil);
if (contact.familyName) ABRecordSetValue(newContact, kABPersonLastNameProperty, (__bridge CFStringRef)contact.familyName, nil);
if (contact.company) ABRecordSetValue(newContact, kABPersonOrganizationProperty, (__bridge CFStringRef)contact.company, nil);
if (contact.jobTitle) ABRecordSetValue(newContact, kABPersonJobTitleProperty, (__bridge CFStringRef)contact.jobTitle, nil);
if (contact.emailAddress) {
    ABMutableMultiValueRef multiEmail = ABMultiValueCreateMutable(kABMultiStringPropertyType);
    ABMultiValueAddValueAndLabel(multiEmail, (__bridge CFTypeRef)(contact.emailAddress), kABWorkLabel, NULL);
    ABRecordSetValue(newContact, kABPersonEmailProperty, multiEmail, NULL);
    CFRelease(multiEmail);
}

if (contact.details) ABRecordSetValue(newContact, kABPersonNoteProperty, (__bridge CFStringRef)contact.details, nil);


if (contact.phone) {
    ABMutableMultiValueRef phoneNumbers = ABMultiValueCreateMutable(kABMultiStringPropertyType);
    ABMultiValueAddValueAndLabel(phoneNumbers, (__bridge CFStringRef)contact.phone, kABPersonPhoneMainLabel, NULL);
    ABRecordSetValue(newContact, kABPersonPhoneProperty, phoneNumbers, nil);
    CFRelease(phoneNumbers);
}

ABAddressBookAddRecord(addressBookRef, newContact, nil);
CFRelease(newContact);

NSArray *allContacts = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBookRef);
for (id record in allContacts){
    ABRecordRef thisContact = (__bridge ABRecordRef)record;
    if (CFStringCompare(ABRecordCopyCompositeName(thisContact), ABRecordCopyCompositeName(newContact), 0) == kCFCompareEqualTo){
        [[[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Existing contact", @"Title for alert view when adding an existing contact") message:NSLocalizedString(@"A contact already exists with the same name. Do you want to add the new contact?", @"Message for alert view when adding an existing contact")
                           cancelButtonItem:[RIButtonItem itemWithLabel:NSLocalizedString(@"No", @"No")]
                           otherButtonItems:[RIButtonItem itemWithLabel:NSLocalizedString(@"Yes", @"Yes")   action:^{
            [self saveInAddressBook:addressBookRef];
        }], nil] show]; //Potential leak of an object

        NSLog(@"Contact exists");
        return;
    }

}

[self saveInAddressBook:addressBookRef]; //Potential leak of an object stored into 'allContacts'
CFRelease(addressBookRef);
NSLog(@"Contact created");
}

+ (void)saveInAddressBook:(ABAddressBookRef)addressBookRef {
    ABAddressBookSave(addressBookRef, nil);
    [[[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Contact added", @"Title for alert view when contact is successfully added to address book") message:nil delegate:nil cancelButtonTitle:NSLocalizedString(@"OK", @"OK") otherButtonTitles:nil] show];
}

有人知道我怎么解决这些问题吗？

Answer 1

你忘了

CFRelease((__bridge CFTypeRef) allContacts);

我想你可以这样说：

for (id record in allContacts){
    ...
}

CFRelease((__bridge CFTypeRef) allContacts);
[self saveInAddressBook:addressBookRef]; //Potential leak of an object stored into 'allContacts'
CFRelease(addressBookRef);
NSLog(@"Contact created");

Answer 2

您可以继续使用APAddressBook，这是一个为Addressbook构建得非常好的框架。

或者，通常帮助我修复与地址簿相关的崩溃的流是通过遵循XCode建议的优化来实现的。

在XCode中对->产品进行分析。

当它完成时，您必须看到一些问题。
