iOS获取exc错误-访问时间->；CFRelease（iPhoneAddressBook）；

为什么我在

CFRelease（iPhoneAddressBook）

上获得exc错误访问权限

如何释放iPhoneAddressBook变量

这是我的密码

ABAddressBookRef iPhoneAddressBook;

iPhoneAddressBook = ABAddressBookCreateWithOptions(NULL, NULL);
dispatch_semaphore_t sema = dispatch_semaphore_create(0);
ABAddressBookRequestAccessWithCompletion(iPhoneAddressBook,  ^(bool granted, CFErrorRef error){
    dispatch_semaphore_signal(sema);
});

dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);

CFErrorRef error;

[self CheckIfGroupExistWithName:@"group name"];

ABRecordRef group = ABAddressBookGetGroupWithRecordID(iPhoneAddressBook, self->groupId);
ABAddressBookAddRecord(iPhoneAddressBook, group, &error);
ABAddressBookSave(iPhoneAddressBook, &error);
//Create new person and save to this group
ABRecordRef record = ABPersonCreate();
BOOL isSuccess ;
ABRecordSetValue(record, kABPersonFirstNameProperty, (__bridge CFTypeRef)(@"name"), nil);

isSuccess = ABAddressBookAddRecord(iPhoneAddressBook, record, &error);
isSuccess = ABAddressBookSave(iPhoneAddressBook, &error);

ABGroupAddMember(group, record, &error);
ABAddressBookSave(iPhoneAddressBook, &error);
CFRelease(record);
CFRelease(group);
CFRelease(iPhoneAddressBook);

这是NSZombie日志：

CFRelease(group);

ABAddressBookGetGroupWithRecordID

不包含

create

或

copy

，因此无需释放对象

解决方案：删除该行

从核心基础内存管理文档：

获取规则
如果您从任何核心基础函数接收对象，而不是 创建或复制函数（如Get函数）不是您自己的 无法确定物体的寿命。如果你想确保 如果您在使用该对象时未处理该对象，则 必须声明所有权（使用CFRetain功能）。那你是 负责在完成后放弃所有权 它

能否尝试在启用NSZombie的情况下运行应用程序。如果你不知道怎么做，谷歌怎么做。然后发布结果日志，我会提供帮助。如果你释放了对象，应用程序正在崩溃bcz一些对象仍在使用

iPhoneAddressBook

清除代码，只有在我们工作完成后才释放它muku说，你的应用程序中的某个点试图访问iPhoneAddressBook，但它不存在，如果在这一点上它崩溃了，这意味着iphoneaddressbook是零，也许它从来没有被创建过？这就是我说的让他把NSZombie放在那里，我们可能会得到它在哪里的线索。@Maro，你试过实现所有的逻辑吗（在

调度信号灯\u等待之后

）

ABAddressBookRequestAccessWithCompletion

completion块的内部？就在

调度信号量信号（sema）之前CFRelease（组）？
