- (void)registerDeviceToken:(id)deviceToken withPayload:(NSDictionary *)payload success:(void (^)(id responseObject))success failure:(void (^)(NSError *error))failure; - (void)unregisterDeviceToken:(id)deviceToken success:(void (^)())success failure:(void (^)(NSError *error))failure;接口設(shè)計(jì)巧妙之處在于支持NSString和NSData兩種設(shè)備令牌格式降低接入成本提供簡(jiǎn)潔的withAlias和靈活的withPayload重載方法使用Block回調(diào)處理異步結(jié)果符合iOS開(kāi)發(fā)習(xí)慣子類實(shí)現(xiàn)策略UrbanAirshipOrbiter和ParseOrbiter通過(guò)重寫(xiě)以下方法實(shí)現(xiàn)服務(wù)差異化requestForRegistrationOfDeviceToken:withPayload:requestForUnregistrationOfDeviceToken:例如ParseOrbiter將注冊(cè)請(qǐng)求改為POST方法- (NSURLRequest *)requestForRegistrationOfDeviceToken:(id)deviceToken withPayload:(NSDictionary *)payload { NSString *path [[self.HTTPManager.baseURL URLByAppendingPathComponent:installations] absoluteString];

if (!self) return nil; self.HTTPManager [[AFHTTPRequestOperationManager alloc] initWithBaseURL:baseURL]; self.HTTPManager.credential credential; AFJSONRequestSerializer *requestSerializer [AFJSONRequestSerializer serializer];

[self.HTTPManager.responseSerializer setAcceptableContentTypes:[NSSet setWithObjects:application/json, text/plain, nil]]; return self; }這段代碼展示了優(yōu)秀的網(wǎng)絡(luò)層設(shè)計(jì)實(shí)踐統(tǒng)一配置JSON序列化器設(shè)置合理的Content-Type接受范圍支持HTTP認(rèn)證憑證設(shè)備令牌標(biāo)準(zhǔn)化處理Orbiter提供了AFNormalizedDeviceTokenStringWithDeviceToken函數(shù)統(tǒng)一處理NSData和NSString類型的設(shè)備令牌static NSString * AFNormalizedDeviceTokenStringWithDeviceToken(id deviceToken) { if ([deviceToken isKindOfClass:[NSData class]]) { const unsigned *bytes [(NSData *)deviceToken bytes];
