奇怪的行为UIActionSheet + UITableView：行消失

Question

我有一个UITableView与其中的一些静态单元格。其中一人触摸时显示UIActionSheet。代码如下：

viewDidLoad：初始化控件。

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 

    [self initializeControls]; 
} 

initializeControls：将手势识别器添加到单元格内的标签以显示UIActionSheet。

- (void)initializeControls { 
    [...] 

    // Places Label 
    self.placeNamesLabel.userInteractionEnabled = YES; 
    tapGesture = \ 
    [[UITapGestureRecognizer alloc] 
    initWithTarget:self action:@selector(didPlaceNamesLabelWithGesture:)]; 
    [self.placeNamesLabel addGestureRecognizer:tapGesture]; 
    tapGesture = nil; 

    [...] 
} 

didPlaceNamesLabelWithGesture：初始化UIActionSheet，加故事板一个UITableView和关闭按钮。

- (void)didPlaceNamesLabelWithGesture:(UITapGestureRecognizer *)tapGesture 
{ 
    // Show UITableView in UIActionView for selecting Place objects. 
    placesActionSheet = [[UIActionSheet alloc] initWithTitle:nil 
                 delegate:nil 
              cancelButtonTitle:nil 
             destructiveButtonTitle:nil 
              otherButtonTitles:nil]; 

    [placesActionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent]; 

    CGRect tableFrame = CGRectMake(0, 40, 0, 0); 

    UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; 
    AddArticlesPlacesViewController *placesView = [storyBoard instantiateViewControllerWithIdentifier:@"PlacesForArticle"]; 
    placesView.managedObjectContext = self.managedObjectContext; 
    placesView.view.frame = tableFrame; 
    [placesActionSheet addSubview:placesView.view]; 
    placesView = nil; 

    UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@"Close"]]; 
    closeButton.momentary = YES; 
    closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f); 
    closeButton.segmentedControlStyle = UISegmentedControlStyleBar; 
    closeButton.tintColor = [UIColor blackColor]; 
    [closeButton addTarget:self action:@selector(dismissPlacesActionSheet:) forControlEvents:UIControlEventValueChanged]; 
    [placesActionSheet addSubview:closeButton]; 
    closeButton = nil; 

    [placesActionSheet showInView:[[UIApplication sharedApplication] keyWindow]]; 

    [placesActionSheet setBounds:CGRectMake(0, 0, 320, 485)]; 
} 

dismissPlacesActionSheet：关闭UIActionSheet。

-(void)dismissPlacesActionSheet:(id)sender { 
    [placesActionSheet dismissWithClickedButtonIndex:0 animated:YES]; } 

一切正常，UITableView从核心数据填充罚款。那么问题在哪里？重点是，当任何行被挖掘，整个表变空（我不能张贴图像，对不起）。

我试着用一个按钮添加一个新的自定义行，将按钮继续添加到AddArticlesPlacesViewController;这工作正常，行为如预期。所以问题出在UIActionSheet和U​​ITableView之间。

下面是两个视图控制器的接口：

主。

@interface AddArticleViewController : UITableViewController <NSFetchedResultsControllerDelegate, [...]> 

[...] 

@property (weak, nonatomic) IBOutlet UILabel *placeNamesLabel; 

@property (strong, nonatomic) NSManagedObjectContext *managedObjectContext; 

[...] 

@end 

中学。

@interface AddArticlesPlacesViewController : UITableViewController <NSFetchedResultsControllerDelegate> 

@property (strong, nonatomic) NSFetchedResultsController *fetchedResultsController; 
@property (strong, nonatomic) NSManagedObjectContext *managedObjectContext; 

@end 

我被卡住了。我究竟做错了什么？

问候。

可以使用的tableview的委托方法：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 

     NSLog(@"indexpath-->%d",indexPath.row); 
     if (indexPath.row==0 || indexPath.row == 2) 
     { 

      NSLog(@"row %d",indexPath.row); 

     } 

     if (indexPath.row==1) 
    { 

      actionsheet=[[UIActionSheet alloc]initWithTitle:@"Sample" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:nil, nil]; 
       [actionsheet showInView:self.view]; 

     } 
    } 

你也可以使用UIActionsheetDelegate的方法选择按钮：

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex 
    { 

     NSLog(@"index==>%d",buttonIndex); 
      NSLog(@"cancel"); 
    }
