从地址簿

Question

我从地址簿获取所有联系人并将其上传到服务器。但有时候它会在 ABRecordCopyValue（person，kABPersonCompositeNameFormatFirstNameFirst）上崩溃

我无法找到崩溃的情景和原因。它不会每次都崩溃。

试试这个方法：

   + (NSArray *)getContactsFromPhoneBook {
        NSMutableArray *contacts = [NSMutableArray array];

        // Request authorization to Address Book
        __block BOOL accessGranted = NO;

        if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"6.0")) {
            addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
        }
        else {
            addressBook = ABAddressBookCreate();
        }
        if (addressBook == NULL) {
            NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
            if (![defaults boolForKey:SHOW_AB_ACCESS_ERROR]) {
