페이징 방법

-(void)fetchNextTwitterPageWithID:(NSString *)objectID { 
    self.twitterClient = [[AFOAuth1Client alloc] initWithBaseURL:[NSURL URLWithString:@"https://api.twitter.com/1.1/"] key:@"XXXXXXXXXXX" secret:@"XXXXXXXXXXXX"]; 

    NSDictionary *parameters = @{ 
           @"max_id" :objectID 
           }; 

    AFOAuth1Token *twitterToken = [AFOAuth1Token retrieveCredentialWithIdentifier:@"TwitterToken"]; 
    [self.twitterClient setAccessToken:twitterToken]; 
    [self.twitterClient registerHTTPOperationClass:[AFJSONRequestOperation class]]; 
    [self.twitterClient getPath:@"statuses/home_timeline.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) { 
     NSMutableArray *responseArray = (NSMutableArray *)responseObject; 
     [responseArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { 
      [tweets addObjectsFromArray:responseObject]; 
      [self.tableView reloadData]; 
     }]; 
     [self.tableView reloadData]; 
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     NSLog(@"Error: %@", error); 
    }]; 
} 

페이지 내가 이해에 따르면

-(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    if([indexPath row] == ((NSIndexPath*)[[tableView indexPathsForVisibleRows] lastObject]).row){ 
     NSDictionary *totalArray = tweets[indexPath.row]; 
     NSString *cellID = [totalArray objectForKey:@"id"]; 
     [self fetchNextTwitterPageWithID:cellID]; 
    } 
}

의 하단을 검출 그러나이 오류 내 응용 프로그램이 실행될 때마다받을 당신이 코드에서, 여기 정정에 대한 내 대답은 :

-(void)fetchNextTwitterPageWithID:(NSString *)objectID { 
    self.twitterClient = [[AFOAuth1Client alloc] initWithBaseURL:[NSURL URLWithString:@"https://api.twitter.com/1.1/"] key:@"XXXXXXXXXXX" secret:@"XXXXXXXXXXXX"]; 
    NSDictionary *parameters = @{ 
           @"max_id" :objectID 
           }; 
    AFOAuth1Token *twitterToken = [AFOAuth1Token retrieveCredentialWithIdentifier:@"TwitterToken"]; 
    [self.twitterClient setAccessToken:twitterToken]; 
    [self.twitterClient registerHTTPOperationClass:[AFJSONRequestOperation class]]; 
    [self.twitterClient getPath:@"statuses/home_timeline.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) { 
     NSArray *responseArray = (NSArray *)responseObject; 
     [tweets addObjectsFromArray:responseArray];
