查詢在parse.com導致我的應用程序退出

Question

驗證碼心不是莫名其妙地工作

//setup cell 
    static NSString *CellIdentifier = @"Cell"; 
    ParseExampleCell *Cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

    PFObject *tempObject = [detailArray objectAtIndex:indexPath.row]; 

    Cell.cellTitle.text = [tempObject objectForKey:@"Exibitor"]; 

即時得到

'NSInvalidArgumentException', reason: '-[UITableViewCell cellTitle]: unrecognized selector sent to instance 0x10d959830' 

我嘗試設置，當用戶點擊一個表項將去到一個詳細視圖控制器Exibitor是在parse.com數據庫中的正確的類

- (id)initWithCoder:(NSCoder *)aCoder { 
    self = [super initWithCoder:aCoder]; 
    if (self) { 
     // Customize the table 

     // The className to query on 
     self.parseClassName = @"Exibitor"; 

     // The key of the PFObject to display in the label of the default cell style 
     //self.textKey = @"name"; 

     // Uncomment the following line to specify the key of a PFFile on the PFObject to display in the imageView of the default cell style 
     //self.imageKey = @"Logo"; 

     // Whether the built-in pull-to-refresh is enabled 
     //self.pullToRefreshEnabled = YES; 

     // Whether the built-in pagination is enabled 
     //self.paginationEnabled = YES; 

     // The number of objects to show per page 
     //self.objectsPerPage = 8; 

    } 


    return self; 

} 



- (void)viewDidLoad 
{ 

    //_itemsArray = [NSMutableArray]; 
    // _detailArray = [NSMutableArray]; 

    [self performSelector:@selector(retrieveFromParse)]; 



    [super viewDidLoad]; 

    // Uncomment the following line to preserve selection between presentations. 
    self.clearsSelectionOnViewWillAppear = NO; 

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller. 
    // self.navigationItem.rightBarButtonItem = self.editButtonItem; 
} 

然後我有代碼的其餘

- (void) retrieveFromParse { 

    PFQuery *query = [PFQuery queryWithClassName:@"Exibitor"]; 
    [query whereKey:@"Wedding" equalTo:[NSNumber numberWithBool:YES]]; 

    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { 
     if (!error) { 
      detailArray = [[NSMutableArray alloc] initWithArray:objects]; 
     } 
     //[detailArray reloadData]; 
    }]; 
} 

多數民衆贊成我有香港專業教育學院把大部分它作爲即時通訊試圖找出究竟發生了什麼上
