인터넷 연결없이 데이터를로드하는 중 오류가 발생했습니다 (Restkit)

Question

RKObjectManager를 통해 나머지를 호출 한 후 인터넷에 연결되어 있지 않을 때 객체를로드하지 않습니다. domain.local로 테스트하고 WIFI는 Off입니다.

"reachabilityObserver"로 구현할 수 있음을 알고 있지만 어떻게해야 할 지 모르겠습니다.

내 코드 :

#import "ViewInformationForm.h" 
#import <RestKit/RestKit.h> 

@interface User : NSObject { 
    NSNumber*  _user_forfait; 
    NSNumber*  _user_client_free; 
    NSNumber*  _user_demande_portabilite; 
    NSNumber*  _user_mail_confirm; 
    NSNumber*  _user_mail_enregistrement_inscrption; 
    NSNumber*  _user_mail_depart_expedition; 
    NSNumber*  _user_mail_arrivee_expedition; 
    NSNumber*  _user_activation; 
    NSNumber*  _user_portabilite; 
} 

@property (nonatomic, retain) NSNumber*  user_forfait; 
@property (nonatomic, retain) NSNumber*  user_client_free; 
@property (nonatomic, retain) NSNumber*  user_demande_portabilite;

@property (nonatomic, retain) NSNumber*  user_mail_arrivee_expedition; 
@property (nonatomic, retain) NSNumber*  user_activation; 
@property (nonatomic, retain) NSNumber*  user_portabilite;

당신의 도움에 감사드립니다. AO.

Answer 1

이것은 당신이 RestKit에 도달 알림을 등록하는 방법입니다 : 여기

// Register for changes in network availability 
NSNotificationCenter* center = [NSNotificationCenter defaultCenter]; 
[center addObserver:self selector:@selector(reachabilityDidChange:) name:RKReachabilityDidChangeNotification object:nil]; 

그리고 당신이 알림을 잡을 :

- (void)reachabilityDidChange:(NSNotification *)notification { 
    RKReachabilityObserver* observer = (RKReachabilityObserver *) [notification object]; 
    RKReachabilityNetworkStatus status = [observer networkStatus]; 
    if (RKReachabilityNotReachable == status) { 
     RKLogInfo(@"No network access!"); 
    } else if (RKReachabilityReachableViaWiFi == status) { 
     RKLogInfo(@"Online via WiFi!"); 
    } else if (RKReachabilityReachableViaWWAN == status) { 
     RKLogInfo(@"Online via Edge or 3G!"); 
    } 
} 

Answer 2

분명히 Iternet 연결이없는 경우 인터넷에서 데이터를로드하지 않습니다. 당신은 예를 들어, 사전 구현 도달 가능성 클래스 중 하나를 시도 할 수 있습니다 : http://developer.apple.com/library/ios/#samplecode/Reachability/Listings/Classes_Reachability_h.html#//apple_ref/doc/uid/DTS40007324-Classes_Reachability_h-DontLinkElementID_5

Answer 3

RKRequest 메서드에 이미 구현되어 있으므로 Restkit 도달 가능성 알림 시스템에 등록 할 필요조차 없습니다.

그래서 인터넷이 연결되지 않은 경우, 요청이 실패하고이 대리인이 (이미 구현 한 수 있음)라고 :

- (void)objectLoader:(RKObjectLoader *)objectLoader didFailWithError:(NSError *)error { 
    // No internet ! 
} 

은 조심,이 대표는 또한 다른 이유로 호출 할 수 있습니다, 데이터 매핑에 오류가있는 경우와 같습니다. 그러나 간단한 경우에 당신이하고 싶은 일은 괜찮을 것입니다!
