我想填充我ViewController內3個不同TableViews（不同tableviews出現基於選擇的UISegmentControl） - sidetableView，neighboursView，和friendsView。前兩個填充完美，但第三個（neighboursView）似乎沒有加載單元格。見下面的代碼。任何想法爲什麼？我覺得我在定義第三個筆尖viewdidLoad錯了？的iOS - 三TableView中的視圖控制器不加載筆尖
ViewController.h

@property (strong, nonatomic) NSMutableArray *friendData;
@property (strong, retain) NSMutableArray *neighbourData;
@property (strong, nonatomic) IBOutlet UITableView *friendsView;

UINib *筆尖= [UINib nibWithNibName：@ 「sidebarCell」 捆綁：無]。 [self.friends查看registerNib：nib forCellReuseIdentifier：@「sidebarCell」]; UINib * nib1 = [UINib nibWithNibName：@「MyFriendTableViewCell」bundle：nil]; [self.sidetableView registerNib：nib1 forCellReuseIdentifier：@「MyFriendTableViewCell」]; UINib * nib2 = [UINib nibWithNibName：@「sidebarCell」bundle：nil]; [self.neighboursView registerNib：nib2 forCellReuseIdentifier：@「sidebarCell」];改變這個並運行 –
