嗨，我想這樣的圖像中顯示的反應，但不顯示，有些錯誤是發生所以請幫我

-(void)getCategories 
{ 
    Service *srv=[[Service alloc]init]; 

    NSString *str=@"http://streamtvbox.com/site/api/matrix/";//?country_code=91&phone=9173140993&fingerprint=2222222222"; 
    NSString *method=@"channels"; 
    NSMutableDictionary *dict=[[NSMutableDictionary alloc]init]; 

    [srv postToURL:str withMethod:method andParams:dict completion:^(BOOL success, NSDictionary *responseObj) 
    { 
     NSLog(@"%@",responseObj); 
     arrayCategories = [responseObj valueForKey:@"categories"]; 
    }]; 
} 


- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    return arrayCategories.count; 
} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 

{ 
    static NSString *simpleTableIdentifier = @"ChannelCell"; 

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier]; 

    if (cell == nil) { 
     cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier]; 
    } 

    cell.textLabel.text = [[arrayCategories objectAtIndex:indexPath.row]valueForKey:@"categories"]; 

    return cell; 
}
