Question

在iOS 6中，此代码始终为Nil提供NSLog，但第一个始终提供正确的复合名称。因此我知道我可以访问地址簿，如果我在addressbook中更改名称，代码会记录正确的复合名称。无论我投放了多少封电子邮件，联系人ABMultiValueGetCount始终为Nil。这是为什么？

ABRecordRef person = (__bridge ABRecordRef)[addressBookArray objectAtIndex:x];

NSLog(@"%@ -", ABRecordCopyCompositeName(person));
NSLog(@"%ld -", ABMultiValueGetCount(ABRecordCopyValue(person, kABPersonEmailProperty)));

Answer 1

得到它......看起来像我应该预期的某种managedObjectContext条件......

在一个View Controller中，我这样做了：

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
addressBookArray = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);
// Prsented info on the user name, but not on the Emails
CFRelease(addressBook);

在第二个视图控制器中，我传递了addressBookArray以尝试保存一些周期然后执行此操作：

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
// Successfully accessed name properties (suspect they were chached some where ?
// Unsuccsfully accessed email properties (they have never been accessed so no chache and I get Null
CFRelease(addressBook);

修复...在secondviewController中重复：

addressBookArray = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);

Bingo问题解决了!!

请检查以下链接。那些可以解决你的问题。在ios6中，苹果已经改变了地址簿的许可。

为什么这个联系人总是以Nil / null出现，即使我设置它或添加电子邮件？
