How to get value from UITableViewCell

I'm having a problem in getting a value in uitableviewcell.

first of all, i have a label on my cell which I've created a tap gesture on it. What i want to do is on tapping that label, viewUser method will be call and it will get the details of that cell being tapped.

Here is my code:

on cellForRowAtIndexPath:

cell.userNameLabel.text = [[_workflowList objectAtIndex:indexPath.row] userName];

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewUser:)];
tapGestureRecognizer.numberOfTapsRequired = 1;
[cell.userNameLabel addGestureRecognizer:tapGestureRecognizer];
cell.userNameLabel.userInteractionEnabled = YES;

Now, when i call my ontap method which is viewUser:

- (IBAction)viewUser:(id)sender {

//this should not be hard coded
//data should come from cell.
//usernamelabel or i will get the index selected 
//and get the details in my array 
// like this --> [_workflowList objectAtIndex:index]

WorkflowProfileViewController *chkDtl = [[WorkflowProfileViewController alloc]init];
chkDtl.name = @"USER, USER USER"; ;
chkDtl.phoneNo = @"09173210836";
chkDtl.email = @"[email protected]";
[self.navigationController pushViewController:chkDtl animated:YES];
}

Please help me on this.

When creating UILable you could put the tag value as row number

lable.tag = indexPath.row

In your method then retrieve label and look for tag value.

Definitely you should use the proper delegate methods instead implementing UITapGestureRecognizer on an UITableViewCell. Then you can get the informations you want pretty easily:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString *theUserNameYouWantToGet = [_workflowList objectAtIndex:[indexPath row]];
}

EDIT:

If you want that action not to work for the whole cell, you could subclass UITableViewCell, add properties to it and implement your own delegate protocol to that cell:

@protocol JWTableViewCellDelegate;
@interface JWTableViewCell : UITableViewCell
@property (nonatomic, retain) NSString *username;
@property (nonatomic, assign) id<JWTableViewCellDelegate>delegate;
@end
@protocol JWTableViewCell <NSObject>
- (void)tableViewCellDidClickUsername:(JWTableViewCell *)cell;
@end

@implementation JWTableViewCell
- (void)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
    if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) {
        [self setupView];
    }
    return self;
}
// if you use a prototyping NIB
- (void)awakeFromNib {
    [self setupView];
}
- (void)setupView {
    // add gesture recognizer
}
- (void)handleGesture {
    if ([_delegate respondsToSelector:@selector(tableViewCellDidClickUsername:)]) {
        [_delegate tableViewCellDidClickUsername:self];
    }
}

Then use this in your viewController:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    JWTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"reuseID" forIndexPath:indexpath];
    [cell setUsername:@"Paul"];
    [cell setDelegate:self];
}
- (void)tableViewCellDidClickUsername:(JWTableViewCell *)cell {
    NSString *theUserNameYouWantToGet = [cell username];

  }

The best option would be to use UITableView delegate method tableView:didSelectRowAtIndexpath: as below:

- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    WorkflowProfileViewController *chkDtl = [[WorkflowProfileViewController alloc]init];
    chkDtl.name=[[_workflowList objectAtIndex:indexPath.row] userName];
    [self.navigationController pushViewController:chkDtl animated:YES];
}

Don't forget to set delegate of your tableView.

UPDATE: Then I think you want to do something like below. In your cellForRowAtaIndexPath: add following:

cell.userNameLabel.tag=indexPath.row;

And in viewUser method:

UITapGestureRecognizer *tap=(UITapGestureRecognizer*)sender;
WorkflowProfileViewController *chkDtl = [[WorkflowProfileViewController alloc]init];
chkDtl.name=[[_workflowList objectAtIndex:tap.view.tag] userName];
[self.navigationController pushViewController:chkDtl animated:YES];

Something like below will get the cell you are tapping (replace swipe with tap):

- (void)handleSwipeRight:(UISwipeGestureRecognizer *)gestureRecognizer{
    CGPoint location = [gestureRecognizer locationInView:self.tableView];
    NSIndexPath *swipedIndexPath = [self.tableView indexPathForRowAtPoint:location];
    self.currentSwipedCell  = [self.tableView cellForRowAtIndexPath:swipedIndexPath];

 }

Havent tested it yet but:

-(void)viewUser:(UITapGestureRecognizer):gestureRecognizer{
    CGPoint location = [gestureRecognizer locationInView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:location];
    self.currentTappedCell  = [self.tableView cellForRowAtIndexPath:indexPath];
    NSLog(self.currentTappedCell.name); // If you have a custom cell with a name property
}
