How do I remove gesture recogniser from a label in a UITableViewCell? - ios

I've bottom toolbar in my ViewController and a TableView above it. The toolbar has a date label in the middle, and next and previous buttons on the left and right. based on the selected date tableview content changes..
Now TableViewCell contains a UILabel. I want to add Gesture to the label only if the selected day is today.
So I wrote in my cell update method
UITapGestureRecognizer gesture = new UITapGestureRecognizer();
gesture.AddTarget(() => HandleValueLabelClick());
if (source.parentController.selectedDateTime.Day == DateTime.Now.Day)
{
AddEditAction();
ValueLabel.AddGestureRecognizer(gesture);
}
else
{
ValueLabel.RemoveGestureRecognizer(gesture);
}
But the gesture remove if the selected date is not today, is not working. Any help is appreciated..

It doesn't work 'cause you are removing a newly created gesture, not the gesture it already may have.
You must retrive the gestures array with ValueLabel.gestureRecognizers then remove each one with a for loop.

SpriteWidget: App doesn't response to handleEvent in NodeWithSize

I created a widget, added some Sprites and made some animation. I want to add some user interaction but handelEvent method is not working. I already set userInteractionEnabled to true.
I tried debugging and place a breakpoint inside the handleEvent method but it didn't stop when I touched the screen.
class MainSceneBackgroundNode extends NodeWithSize {
Sprite _logo;
RepeatedImage _background;
GuyImage _guy;
int _i = 0;
int _j = 0;
int _dir = -1;
MainSceneBackgroundNode() : super(new Size(2560.0, 1440.0)) {
userInteractionEnabled = true;
handleMultiplePointers = false;
// Add background
_background = new RepeatedImage(_imageMap["assets/background.png"]);
addChild(_background);
_guy = new GuyImage();
addChild(_guy);
_logo = new Sprite.fromImage(_imageMap["assets/logo.gif"]);
_logo.pivot = Offset.zero;
_logo.size = new Size(912, 486);
_logo.position = new Offset(824, 10);
addChild(_logo);
}
#override
bool handleEvent(SpriteBoxEvent event) {
if (event.type == PointerDownEvent) {
if (event.boxPosition.dx < 1280) {
_dir = -1;
} else {
_dir = 1;
}
}
return true;
}
...
}
Any suggestion will be appreciated. I don't know what else to do.
Thanks in Advance.

UITableView with SearchView makes new cells overlap old ones on search

Iam implementing a SearchView to filter the data in my UITableView. Iam able to search successfully, the only issue is when the UITableView data gets filtered, the old cells still exist and the filtered ones overlap them giving me a messy output. I have cleared the Table source as suggested by my answers on SO, but still not resolved the problem.
Here is what Iam trying to do:
FilterController
void searchFiler_TextChanged(object sender, UISearchBarTextChangedEventArgs e)
{
if (!string.IsNullOrEmpty(e.SearchText))
{
ppTable.Source = null;
AppDelegate.filteredList = null;
ppTable.ReloadData();
filteredModelList = filter(dupes, e.SearchText);
mAdapter = new PeoplePlacesSource(filteredModelList, "");
ppTable.Source = mAdapter;
ppTable.ReloadData();
}
else
{
ppTable.Source = null;
mAdapter = new PeoplePlacesSource(dupes, "");
searchFiler.TextChanged += searchFiler_TextChanged;
mAdapter.TableRowSelected += mAdapter_TableRowSelected;
ppTable.Source = mAdapter;
ppTable.ReloadData();
}
}
PeoplePlacesSource
public override UITableViewCell GetCell(UITableView tableView, Foundation.NSIndexPath indexPath)
{
cell = tableView.DequeueReusableCell("PeoplePlacesCell_Cell") as PeoplePlacesCell ?? PeoplePlacesCell.Create();
subList = userList.ElementAt(indexPath.Row);
cell.UpdatePeoplePlacesCell(subList);
return cell;
}
PeoplePlacesCell
internal void UpdatePeoplePlacesCell(System.Linq.IGrouping<string, Models.EmployeeModel> subList)
{
var yPosition =15;
var xPosition = 10;
var imgDefault = new UIImageView();
imgDefault.Frame = new CoreGraphics.CGRect(10, viewParent.Frame.Y, 60,60);
imgDefault.Image = UIImage.FromFile("ic_appicon.png");
CALayer profileImageCircle = imgDefault.Layer;
profileImageCircle.CornerRadius = 28;
profileImageCircle.BorderWidth = 2;
profileImageCircle.BorderColor = new CoreGraphics.CGColor(211, 34, 41);
profileImageCircle.MasksToBounds = true;
imgDefault.ClipsToBounds = true;
viewParent.AddSubview(imgDefault);
var labelUserName = new UILabel();
labelUserName.Frame = new CoreGraphics.CGRect(0, 0, viewContainer.Frame.Width, 30);
labelUserName.TextColor = UIColor.FromRGB(211, 34, 41);
labelUserName.Text = subList.Key ;
labelUserName.ClipsToBounds = true;
labelUserName.Font = UIFont.BoldSystemFontOfSize(17);
viewContainer.AddSubview(labelUserName);
var mList = subList.Take(5);
foreach (var employeeModel in mList)
{
var labelPlace = new UILabel();
labelPlace.Frame = new CoreGraphics.CGRect(0, yPosition, viewContainer.Frame.Width, 50);
if (employeeModel.Place.Contains(","))
{
labelPlace.Text = employeeModel.Place.Substring(0, employeeModel.Place.IndexOf(","));
}
else
{
labelPlace.Text = employeeModel.Place;
}
labelPlace.Font = UIFont.FromName(labelPlace.Font.Name, 12f);
labelUserName.SizeToFit();
labelPlace.ClipsToBounds = true;
viewContainer.AddSubview(labelPlace);
yPosition += 15;
}
}
How can I solve this? Any help is appreciated
Do you have the same problem after scroll? You cells are reused, but I don't see code for removing added subviews. Try to remove all subviews you added, before reusing cells.

How to add text input field in cocos2d.Android cocos sharp?

I am trying to get CCTextFieldTTF to work in cocos sharp with Xamarin for an android application. But can't get hold of this for the life of me. Could not find any documentation on cocos sharp API either. Does anyone know how to use this class to render a text area in an android application? The reason I am asking is in a xamarin forum I saw someone saying that this does not work in the API yet. Any help would be highly appreciated. Thanks in advance.
I have this working in android
Here is the sample code:
Create a node to track the textfield
CCTextField trackNode;
protected CCTextField TrackNode
{
get { return trackNode; }
set
{
if (value == null)
{
if (trackNode != null)
{
DetachListeners();
trackNode = value;
return;
}
}
if (trackNode != value)
{
DetachListeners();
}
trackNode = value;
AttachListeners();
}
}
//create the actual input textfield
var textField = new CCTextField(string.Empty, "Somefont", 25, CCLabelFormat.SystemFont);
textField.IsColorModifiedByOpacity = false;
textField.Color = new CCColor3B(Theme.TextWhite);
textField.BeginEditing += OnBeginEditing;
textField.EndEditing += OnEndEditing;
textField.Position = new CCPoint (0, 0);
textField.Dimensions = new CCSize(VisibleBoundsWorldspace.Size.Width - (160 * sx), vPadding);
textField.PlaceHolderTextColor = Theme.TextYellow;
textField.PlaceHolderText = Constants.TextHighScoreEnterNamePlaceholder;
textField.AutoEdit = true;
textField.HorizontalAlignment = CCTextAlignment.Center;
textField.VerticalAlignment = CCVerticalTextAlignment.Center;
TrackNode = textField;
TrackNode.Position = pos;
AddChild(textField);
// Register Touch Event
var touchListener = new CCEventListenerTouchOneByOne();
touchListener.OnTouchBegan = OnTouchBegan;
touchListener.OnTouchEnded = OnTouchEnded;
AddEventListener(touchListener);
// The events
bool OnTouchBegan(CCTouch pTouch, CCEvent touchEvent)
{
beginPosition = pTouch.Location;
return true;
}
void OnTouchEnded(CCTouch pTouch, CCEvent touchEvent)
{
if (trackNode == null)
{
return;
}
var endPos = pTouch.Location;
if (trackNode.BoundingBox.ContainsPoint(beginPosition) && trackNode.BoundingBox.ContainsPoint(endPos))
{
OnClickTrackNode(true);
}
else
{
OnClickTrackNode(false);
}
}
public void OnClickTrackNode(bool bClicked)
{
if (bClicked && TrackNode != null)
{
if (!isKeyboardShown)
{
isKeyboardShown = true;
TrackNode.Edit();
}
}
else
{
if (TrackNode != null)
{
TrackNode.EndEdit();
}
}
}
private void OnEndEditing(object sender, ref string text, ref bool canceled)
{
//((CCNode)sender).RunAction(scrollDown);
Console.WriteLine("OnEndEditing text {0}", text);
}
private void OnBeginEditing(object sender, ref string text, ref bool canceled)
{
//((CCNode)sender).RunAction(scrollUp);
Console.WriteLine("OnBeginEditing text {0}", text);
}
void AttachListeners()
{
// Attach our listeners.
var imeImplementation = trackNode.TextFieldIMEImplementation;
imeImplementation.KeyboardDidHide += OnKeyboardDidHide;
imeImplementation.KeyboardDidShow += OnKeyboardDidShow;
imeImplementation.KeyboardWillHide += OnKeyboardWillHide;
imeImplementation.KeyboardWillShow += OnKeyboardWillShow;
imeImplementation.InsertText += InsertText;
}
void DetachListeners()
{
if (TrackNode != null)
{
// Remember to remove our event listeners.
var imeImplementation = TrackNode.TextFieldIMEImplementation;
imeImplementation.KeyboardDidHide -= OnKeyboardDidHide;
imeImplementation.KeyboardDidShow -= OnKeyboardDidShow;
imeImplementation.KeyboardWillHide -= OnKeyboardWillHide;
imeImplementation.KeyboardWillShow -= OnKeyboardWillShow;
imeImplementation.InsertText -= InsertText;
}
}
This is all taken from the link below but needed a bit of additional work to get it working on each platform.

add sub view if it doesn't exist

on item click I add sub view (UIButton) to my supper view and want to remove it old one when user click again or just change title it isn't first click.
this is my custom renderer:
var text = new UIButton ();
protected override void OnElementChanged (ElementChangedEventArgs<Image> e)
{
base.OnElementChanged (e);
if (Control == null)
return;
if (this.Element != null) {
Original = (SpecLogoImage)this.Element;
}
TargetView = Control as UIImageView;
text.Layer.CornerRadius = 5;
text.Font = UIFont.FromName ("DIN Condensed", text.Font.PointSize);
text.TouchUpInside += delegate {
text.RemoveFromSuperview ();
};
var rec = new UILongPressGestureRecognizer (() => {
text.SetTitle(Original._hint, UIControlState.Normal);
text.TitleLabel.LineBreakMode = UILineBreakMode.WordWrap;
text.SizeToFit ();
text.Frame = new CGRect ((UIApplication.SharedApplication.KeyWindow.Frame.Width / 2.0f) - (250 / 2.0f),
this.Superview.Superview.Superview.Frame.Height / 2.0f, 250, text.Frame.Height);
if (text.Superview==null) {
Animate (0.6f, () => {
this.Superview.Superview.Superview.AddSubview (text);
}, () => {
text.Layer.ZPosition = int.MaxValue;
});
}
});
text.SetTitleColor (UIColor.White, UIControlState.Normal);
text.BackgroundColor = UIColor.Black;
TargetView.UserInteractionEnabled = true;
TargetView.AddGestureRecognizer (rec);
}
}
every time user click Superview is null, what is the problem ?

Actionscript3 ArgumentError: Error #2109:

Making a touch based platform game based in actionscript 3 using Gary Rosenzweig's game as a basis, all was going well until today, I've been trying to swap out floor objects etc without changing much of the actionscript at all and I have the following error.
ArgumentError: Error #2109: Frame label jump not found in scene jump.

The error is with the following line and is occurring because the referenced MovieClip does not have a frame labelled "jump":
char.mc.gotoAndStop(char.animstate);
My guess is that you made a change to the MovieClip which contains your character and, in doing so, removed the label which the code above references.
