[ios] CallKit - CallDirectoryExtension

참조 : https://developer.apple.com/reference/callkit

-

CallKit framework 는 VoIP 앱이 일반 전화를 쓰는 것처럼 UX 를 가져갈 수 있게 해준다.

LockScreen 에서 incoming call 에 대한 view 를 보고 응답도 할 수 있다.

VoIP 에서 Favorite 과 최근 통화 뷰도 다룰 수 있다.

-

CallKit 은 app extension 형태( CallDirectory )로 수신차단과 발신자 정보 표시(caller identification) 기능을 사용할 수도 있다.

CXCallDirectoryExtensionContext : NSExtensionContext

- (void)addBlockingEntryWithNextSequentialPhoneNumber:(NSString*)phoneNumber;

- (void)addIdentificationEntryWithNextSequentialPhoneNumber:(NSString *)phoneNumber 

                                                      label:(NSString *)label;

- (void)completeRequestWithCompletionHandler:(void (^)(BOOL expired))completion;

(NSExtensionContext 함수)

- (void)completeRequestReturningItems:(nullable NSArray *)items completionHandler:(void(^ __nullable)(BOOL expired))completionHandler;

- (void)cancelRequestWithError:(NSError *)error;

- (void)openURL:(NSURL *)URL completionHandler:(void (^ __nullable)(BOOL success))completionHandler;

-

CXCallDirectoryManager

- (void)reloadExtensionWithIdentifier:(NSString *)identifier completionHandler:(void (^)(NSError *error))completion;

- (void)getEnabledStatusForExtensionWithIdentifier:(NSString *)identifier 

                                 completionHandler:(void (^)(CXCallDirectoryEnabledStatus enabledStatus, NSError *error))completion;

+ (CXCallDirectoryManager *)sharedInstance;

-

CXCallDirectoryProvider

- (void)beginRequestWithExtensionContext:(CXCallDirectoryExtensionContext *)context;

-

App 에서 CXCallDirectoryManager 의

- (void)reloadExtensionWithIdentifier:(NSString *)identifier completionHandler:(nullable void (^)(NSError *_Nullable error))completion;

함수를 부르면 Extension 의 Callback 이 불린다.

Setting -> Phone -> Call Blocking & identification 이 켜져 있다면 CallDirectoryExtension 의 - (void)beginRequestWithExtensionContext:(CXCallDirectoryExtensionContext *)context 함수가 불린다.

-

CXCallDirectoryManager 의

- (void)getEnabledStatusForExtensionWithIdentifier:(NSString *)identifier completionHandler:(void (^)(CXCallDirectoryEnabledStatus enabledStatus, NSError *_Nullable error))completion;

함수를 부르면 extension 의 status 를 알 수 있다.
