Odd behavior UIActionSheet + UITableView: rows disappear - iphone

Question

I've a UITableView with some static cells in it. One of them shows a UIActionSheet when touched. Here goes the code for it:
viewDidLoad: initialize controls.
- (void)viewDidLoad
{
[super viewDidLoad];
[self initializeControls];
}
initializeControls: add gesture recognizer to the label within the cell in order to show the UIActionSheet.
- (void)initializeControls {
[...]
// Places Label
self.placeNamesLabel.userInteractionEnabled = YES;
tapGesture = \
[[UITapGestureRecognizer alloc]
initWithTarget:self action:#selector(didPlaceNamesLabelWithGesture:)];
[self.placeNamesLabel addGestureRecognizer:tapGesture];
tapGesture = nil;
[...]
}
didPlaceNamesLabelWithGesture: initialize UIActionSheet, add a UITableView from StoryBoard and a Close button.
- (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: close UIActionSheet.
-(void)dismissPlacesActionSheet:(id)sender {
[placesActionSheet dismissWithClickedButtonIndex:0 animated:YES]; }
Everything works and the UITableView populates fine from Core Data. So where is the problem? The point is that when any row is tapped, the entire table gets empty (I can't post images yet, sorry).
I've tried to add a new custom row with a button that fires a push segue to the AddArticlesPlacesViewController; this works fine and the behavior is as expected. So the problem is between UIActionSheet and UITableView.
Here are the interfaces for both view controllers:
Main.
#interface AddArticleViewController : UITableViewController <NSFetchedResultsControllerDelegate, [...]>
[...]
#property (weak, nonatomic) IBOutlet UILabel *placeNamesLabel;
#property (strong, nonatomic) NSManagedObjectContext *managedObjectContext;
[...]
#end
Secondary.
#interface AddArticlesPlacesViewController : UITableViewController <NSFetchedResultsControllerDelegate>
#property (strong, nonatomic) NSFetchedResultsController *fetchedResultsController;
#property (strong, nonatomic) NSManagedObjectContext *managedObjectContext;
#end
I'm stuck. What am I doing wrong?

Answer 1

you can use tableview's delegate method:
- (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];
}
}
And you can use UIActionsheetDelegate's method for Selected Button:
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(#"index==>%d",buttonIndex);
NSLog(#"cancel");
}
