使用切換啓用 - 禁用IOS聯繫人訪問

Question

當用戶使用切換禁用（禁用）時，我需要關閉myApp中的聯繫人訪問。 當切換開啓（啓用）時，也可以獲得聯繫人權限。

有任何想法如何解決。

首先，我想讓你知道，蘋果不允許以任何授權的方式修改隱私設置，程序化........所以，如果你想處理這個問題，你可以檢查許可，如果它被授予或沒有.....然後你可以處理你的事件a/c到....這種方法將從本機操作系統發出警報，要求訪問....

//Ask user to grant the permission to access contacts 
- (void)requestPermissionForContactsAccessAndFetchWithCompletion 
{ 
    ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus(); 

    if (status != kABAuthorizationStatusAuthorized && status != kABAuthorizationStatusNotDetermined) { 
     // tell user to enable contacts in privacy settings 
     NSLog(@"You previously denied access: You must enable access to contacts in settings"); 
    } 

    CFErrorRef error = NULL; 
    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &error); 
    if (error) 
    { 
     if (addressBook) CFRelease(addressBook); 

    } 
    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) { 

     if (error) { 
      NSLog(@"ABAddressBookRequestAccessWithCompletion error: %@", CFBridgingRelease(error)); 
     } 

     if (granted) { 
     //Get all contact if access is granted--This will call when access granted 
     [self getContactsFromAddressBook:addressBook]; 

     }else{ 


     } 

    }); 

} 

讓我知道你是否需要更多幫助....
