Question

我试图从我的Facebook专辑中读取图片。

这是我用来阅读相册的代码：

- (void)storePhotoIntoCoreDataFromAlbumId:(NSString *)albumId whitAlbumName:(NSString *)albumName
{
    if (FBSession.activeSession.isOpen) {
        NSString *request = [NSString stringWithFormat:@"/%@/photos",albumId];
        [FBRequestConnection startWithGraphPath:request
                              completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                                  if (!error) {
                                      if ([result isKindOfClass:[NSDictionary class]]) {
                                          if ([[result valueForKeyPath:@"data"] isKindOfClass:[NSArray class]]) {
                                              NSString *firstPageToRead = [result valueForKeyPath:@"paging.next"];
                                              [self storePicture:[result valueForKey:@"data"] withAlbumTitle:albumName];
                                              if (firstPageToRead) {
                                                  [self pagingQueryUntil:firstPageToRead];
                                              }

                                          }
                                      }
                                  } else {
                                      NSLog(@"Errore: %@", error);
                                  }
                              }
         ];
    }
}

此代码效果很好，它在[pagingQueryUntil:firstPageToRead]方法中的问题。我使用这种方法，以防同一张专辑中有很多图片，我不能一次性阅读。

在这种方法中，我将连接到页面以读取其中的图片：

- (void)pagingQueryUntil:(NSString *)until {
    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                            until, @"until",
                            nil];
    [FBRequestConnection startWithGraphPath:@"/me/photos"
                                 parameters:params
                                 HTTPMethod:@"GET"
                          completionHandler:^(
                                              FBRequestConnection *connection,
                                              id result,
                                              NSError *error
                                              ) {
 NSLog(@"Errore: %@", error);

}

我收到了这个错误：

Error Domain=com.facebook.sdk Code=5 "The operation couldn’t be completed. (com.facebook.sdk error 5.)" UserInfo=0xd092be0 {com.facebook.sdk:HTTPStatusCode=400, com.facebook.sdk:ParsedJSONResponseKey={

        error =         {
            code = 100;
            message = "(#100) Must be a unixtime or a date/time representation parseable by strtotime()";
            type = OAuthException;
        };
    };
    code = 400;
}, com.facebook.sdk:ErrorSessionKey=<FBSession: 0xd089520, state: FBSessionStateOpen, loginHandler: 0x0, appID: 581914168536264, urlSchemeSuffix: , tokenCachingStrategy:<FBSessionTokenCachingStrategy: 0xd1b0960>, expirationDate: 2014-07-19 08:35:28 +0000, refreshDate: 2014-05-20 08:36:52 +0000, attemptedRefreshDate: 0001-12-30 00:00:00 +0000, permissions:(

    "user_location",
    "public_profile",
    email,
    "user_birthday",
    "user_friends",
    "friends_photos"
)>}

问题是什么？

Answer 1

我冒昧地告诉你传递给pagingQueryUntil的字符串不符合here概述的支持日期和时间格式之一。因此，API会返回您看到的错误：

message = "(#100) Must be a unixtime or a date/time representation parseable by strtotime()";

当我尝试从facebook上阅读图片时，Error Domain = com.facebook.sdk Code = 5
