在我的应用程序中我收到联系信息直接购买这样做...

ABAddressBookRef m_addressbook = ABAddressBookCreate();

CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(m_addressbook);

CFIndex nPeople = ABAddressBookGetPersonCount(m_addressbook);

for (int i=0;i < nPeople;i++)
{
    ABRecordRef ref = CFArrayGetValueAtIndex(allPeople,i);
    CFStringRef company,firstName,lastName;

     firstName = ABRecordCopyValue(ref, kABPersonFirstNameProperty);
     lastName  = ABRecordCopyValue(ref, kABPersonLastNameProperty);
     company = ABRecordCopyValue(ref, kABPersonOrganizationProperty);
}

因此,我需要首先检查这是否为我的应用程序的开/关设置 - >隐私 - >联系人开/关.

为此,我这样做:

__block BOOL accessGranted = NO;


float sysver = [[[UIDevice currentDevice]systemVersion]floatValue];

if(sysver>=6) {
    ABAddressBookRef addressBook = ABAddressBookCreate();

    if (ABAddressBookRequestAccessWithCompletion != NULL) {  
        dispatch_semaphore_t sema = dispatch_semaphore_create(0);
        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
            accessGranted = granted;
            dispatch_semaphore_signal(sema);});

     dispatch_semaphore_wait(sema, …
