Ios 如何创建通讯簿和联系人

我已经为通讯录和显示联系人的联系人创建了一个代码。它工作正常，但突然出现运行时错误。因为我是ios新手。我找不到错误。堆栈溢出中的任何人都可以告诉我错误

对于（CFIndex i=0；i错误在于，因为在IOS6上，苹果添加了一些功能，没有人有权在未经所有者许可的情况下获取内容。
在IOS6上，苹果引入了新的隐私控制，用户可以控制每个应用程序对联系人和日历的访问。因此，在代码方面，您需要添加一些方式来请求权限。在在5号或之前，我们随时可以打电话

ABAddressBookRef addressBook = ABAddressBookCreate();

要获取地址簿没有任何问题，但在iOS6中，如果您没有权限，此调用将只返回空指针。这就是为什么我们需要更改方法以获取ABAddressBookRef

这种类型的错误通常在未授予访问通讯簿的权限时出现。在这种情况下，请添加此代码

__block BOOL accessGranted = NO;
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
    dispatch_semaphore_t sema = dispatch_semaphore_create(0);
    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
        accessGranted = granted;
        dispatch_semaphore_signal(sema);
    });
    dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
    dispatch_release(sema);   
}
else { // we're on iOS 5 or older
    accessGranted = YES;
}

if (accessGranted) {
    // Do whatever you want here.
}
