Problems using UIPanGestureRecognizer in UITableViewCell

[jasanchezsa]

First congratulations for the project.

I'm trying to add a table in a UIViewController but the swipe gesture is not working properly. I tried with the following delegates GestureRecognizerDelegates:

• (BOOL)gestureRecognizerShouldBegin:(UIPanGestureRecognizer *)gestureRecognizer
• (BOOL)gestureRecognizer:(UIGestureRecognizer )gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer )otherGestureRecognizer

I have also tried the fault property: requireGestureRecognizerToFail

Any idea?

Thank you very much.

Can you please post more of your code? Specifically the class with that tableview or the portion of your class that creates and adds the tableview.

For example I added UITableView. The problem is that the method is called before didSelectRowAtIndexPath that uipangesturerecognizer and not moving to another controller.

My code:

#import <UIKit/UIKit.h>
#import "ContentViewController.h"
#import "SeccionTableCell.h"

@interface PortadaViewController : ContentViewController <UITableViewDataSource, UITableViewDelegate, SeccionTableCellDelegate>

@property (nonatomic, weak) IBOutlet UITableView *myTableView;
@property (nonatomic, strong) NSMutableArray *arrayContentData;

//-----------------------------------------------------------------------------------------------------------

#import "PortadaViewController.h"

@interface PortadaViewController ()

@end

@implementation PortadaViewController

@synthesize arrayContentData;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

#pragma mark -
#pragma mark - viewDidLoad
#pragma mark -

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.

    [self.view setBackgroundColor:[UIColor clearColor]];

    [self.myTableView setFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y+self.heightHeader, self.view.frame.size.width, self.view.frame.size.height-self.heightHeader)];

    arrayContentData = [[NSMutableArray alloc] initWithObjects:@"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", @"1", nil];
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [arrayContentData count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"SimpleTableCell";
    SeccionTableCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil)
    {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SeccionTableCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];

        [cell setDelegate:self];
        [cell drawElementsScroll];
    }

    cell.imageViewFoto.image = [UIImage imageNamed:@"sample.png"];
    cell.labelTitulo.text = [arrayContentData objectAtIndex:indexPath.row];

    return cell;
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return TABLE_SECCION_CELL_HEIGHT;
}

#pragma mark -

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:NO];
    NSLog(@"PUSH CELL");
}

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
}

Thank you very much!

It's tough to say what the issue is without inspecting the code further. I have used a modified version of this project to manage a set of ViewControllers each containing a UITableView so it's definitely possible. I think you're on the right track with making sure the gestures play nice with one another. Within those delegate methods you would check to see which gestures you are being asked about. Or you could do that in the ContainerViewController. Good luck!

@elpatxificador,

I pushed some changes today and updated the README, take a look at the updated code and let me know if you're still having a problem. Best of luck.
