Calling uipangesture from uitableviewcell class when tapped a cell - ios

Question

I am using ABMenuTableViewCell tableview controller in my application. I want to call didSelectRowAtIndexPath when i swipe a UITableViewCell.
Right now didSelectRowAtIndexPath only execute when I tap on a cell, I want to call it even when I swipe it. here is my didSelectRowAtIndexPath and cellforRowAtIndexPath methods code.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UILabel *likes;
UILabel *downloads;
static NSString *CellIdentifier = #"Cell";
ABMenuTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[ABMenuTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
arrow = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"acc_arrow_back.png"]];
arrow.frame = CGRectMake(300, 50, 5, 12);
arrow.image = [arrow.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
[arrow setTintColor:[UIColor colorWithRed:(191/255.0) green:(2/255.0) blue:(6/255.0) alpha:1]];
[cell.contentView addSubview:arrow];
UIImageView *likes_img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"social.png"]];
likes_img.frame = CGRectMake(15, 80, 15, 15);
likes_img.image = [likes_img.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
[likes_img setTintColor:[UIColor colorWithRed:(191/255.0) green:(2/255.0) blue:(6/255.0) alpha:1]];
[cell.contentView addSubview:likes_img];
likes =[[UILabel alloc]initWithFrame:CGRectMake(33, 78, 80, 20)];
likes.tag = 1001; // set a tag for this View so you can get at it later
likes.textColor=[UIColor darkGrayColor];
likes.font=[UIFont fontWithName:#"Helvetica" size:10.0f];
likes.text=[[rssOutputData objectAtIndex:indexPath.row]xmllikes];
[cell.contentView addSubview:likes];
cell.detailTextLabel.textColor = [UIColor darkGrayColor];
UIImageView *downloads_img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"download.png"]];
downloads_img.frame = CGRectMake(55, 79, 15, 15);
downloads_img.image = [downloads_img.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
[downloads_img setTintColor:[UIColor colorWithRed:(191/255.0) green:(2/255.0) blue:(6/255.0) alpha:1]];
[cell.contentView addSubview:downloads_img];
downloads =[[UILabel alloc]initWithFrame:CGRectMake(73, 78, 80, 20)];
downloads.tag = 1002; // set a tag for this View so you can get at it later
downloads.textColor=[UIColor darkGrayColor];
downloads.font=[UIFont fontWithName:#"Helvetica" size:10.0f];
downloads.text=[[rssOutputData objectAtIndex:indexPath.row]xmldownloads];
[cell.contentView addSubview:downloads];
cell.detailTextLabel.textColor = [UIColor darkGrayColor];
}
else
{
// use viewWithTag to find lblNombre in the re-usable cell.contentView
likes = (UILabel *)[cell.contentView viewWithTag:1001];
downloads = (UILabel *)[cell.contentView viewWithTag:1002];
}
cell.textLabel.text = [[rssOutputData objectAtIndex:indexPath.row]xmlsinger];
cell.detailTextLabel.text = [[rssOutputData objectAtIndex:indexPath.row]xmltitle];
// custom menu view
NSString *nibName = #"ABCellMailStyleMenuView";
ABCellMenuView *menuView = [ABCellMenuView initWithNib:nibName bundle:nil];
menuView.delegate = self;
menuView.indexPath = indexPath;
cell.rightMenuView = menuView;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
And these are the methods in cell class
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer and
- (void)swipeGesture:(UIPanGestureRecognizer *)gesture
here is when i swipe

Answer 1

You can modified swipeGesture method will following code. it will show UITableViewCell as selected once you perform swipe operation.
- (void)swipeGesture:(UIPanGestureRecognizer *)gesture {
if (gesture.state == UIGestureRecognizerStateBegan) {
NSInteger direction;
// find swipe direction
CGPoint velocity = [gesture velocityInView:self];
if (velocity.x > 0) {
// towards right - hide menu view
direction = ABMenuUpdateHideAction;
}
else {
// towards left - show menu view
direction = ABMenuUpdateShowAction;
}
UITableView* tableView = (UITableView*)self.superview.superview;
CGPoint swipeLocation = [gesture locationInView:tableView];
NSIndexPath *swipedIndexPath = [tableView indexPathForRowAtPoint:swipeLocation];
[tableView selectRowAtIndexPath:swipedIndexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
[self updateMenuView:direction animated:YES];
}
}
Hope this help you.

As you are trying to achieve behaviour not supported by ABMenuTableViewCell, you will need to edit it's source:
Add _tapGesture and _menuVisible instance variables:
#implementation ABMenuTableViewCell {
CGRect _rightMenuViewInitialFrame;
UIPanGestureRecognizer *_swipeGesture;
UITapGestureRecognizer *_tapGesture;
BOOL _menuVisible;
}
Implement -tapGesture: method:
- (void) tapGesture:(UITapGestureRecognizer*)gesture {
if (_menuVisible)
[self updateMenuView:ABMenuUpdateHideAction animated:YES];
else
[self updateMenuView:ABMenuUpdateShowAction animated:YES];
}
Add UITapGestureRecognizer inside -commonInit method:
- (void) commonInit {
_swipeGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:#selector(swipeGesture:)];
_swipeGesture.delegate = self;
[self addGestureRecognizer:_swipeGesture];
_tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapGesture:)];
_tapGesture.delegate = self;
[self addGestureRecognizer:_tapGesture];
}
Update _menuVisible inside -updateMenuView:animated::
- (void)updateMenuView:(ABMenuUpdateAction)action animated:(BOOL)animated {
...
switch (action) {
case ABMenuUpdateShowAction:
menuNewFrame = CGRectMake(CGRectGetWidth(self.contentView.frame) - initialWidth, .0, initialWidth, CGRectGetHeight(self.contentView.frame));
_menuVisible = YES;
break;
case ABMenuUpdateHideAction:
menuNewFrame = CGRectMake(CGRectGetWidth(self.contentView.frame), .0, .0, CGRectGetHeight(self.contentView.frame));
_menuVisible = NO;
break;
default:
break;
}
...
}
You won't be able to select cells, but as I understand it, you don't want to.

If you want the method to be called when swiping the cell, you should be using a UISwipeGestureRecognizer and not a UIPanGestureRecognizer.
In your viewDidLoad:, set up the gesture recognizer.
// Create a left swipe gesture recognizer
UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(handleSwipeLeft:)];
[recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];
// Add it to the table view
[self.tableView addGestureRecognizer:recognizer];
Handle the swipe.
- (void)handleSwipeLeft:(UISwipeGestureRecognizer *)gestureRecognizer
{
// Get location of the swipe
CGPoint location = [gestureRecognizer locationInView:self.tableView];
//Get the corresponding index path within the table view
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:location];
// Check if index path is valid
if (indexPath)
{
// Select the cell at the indexPath
[self.tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
}
}
That should call the tableView: didSelectRowAtIndexPath: method.
