读取iPhone中的通讯录信息

添加AddressBook这个包；
然后#import <AddressBook/AddressBook.h>

//取得本地通信录名柄
    ABAddressBookRef addressBook;
    
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 6.0){
        addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
        //等待同意后 向下执行
        dispatch_semaphore_t sema = dispatch_semaphore_create(0);       
　　　　 ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error)                                            {
            dispatch_semaphore_signal(sema);
        });
        dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
        
    }else{
        addressBook = ABAddressBookCreate();
    }
    
    //取得本地所有联系人信息
    CFArrayRef results = ABAddressBookCopyArrayOfAllPeople(addressBook);
    for(int i = 0; i < CFArrayGetCount(results); i++){
        ABRecordRef person = CFArrayGetValueAtIndex(results, i);
        
        //读取firstname
        NSString *firstName = (__bridge NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);
        //读取lastname
        NSString *lastName = (__bridge NSString*)ABRecordCopyValue(person, kABPersonLastNameProperty);
        //读取电话号码
        NSString *phoneNum;
        ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty);
        for (int k = 0; k < ABMultiValueGetCount(phone); k++){
            phoneNum = (__bridge NSString*)ABMultiValueCopyValueAtIndex(phone, k);
        }
        NSLog(@"firstName:%@ - lastName:%@ - phoneNum:%@",firstName,lastName,phoneNum);
    }
