How to know the UITableview row number
(10 answers)
Closed 5 years ago.
I have a UITableview with multiple cells. On each cell I'm adding buttons dynamically according to some array count. So, when I click on a button I'm able to get the tag value of the button. But how to get the indexPath of that cell?
Here is my code in -cellForRowAtIndexPath:
UIView *view=(UIView*)[cell.contentView viewWithTag:indexPath.row+444];
UIImageView *img=(UIImageView*)[cell.contentView viewWithTag:indexPath.row+999];
img.image=[UIImage imageNamed:#"BHCS_empty.png"];
if(integer!=50)
{
NSInteger y_axis=0;
NSArray *Arr=[tableSubCategoryArr objectAtIndex:indexPath.row];
img.image=[UIImage imageNamed:#"BHCS_selected.png"];
view.Frame= CGRectMake(0,50,281, integer-50);
for (int i=0; i<[Arr count]; i++)
{
NSLog(#"arr %#",[Arr objectAtIndex:i]);
UIButton *Btn=[UIButton buttonWithType: UIButtonTypeCustom];
Btn.frame=CGRectMake(0, y_axis, 281, 44);
[Btn setImage:[UIImage imageNamed:#"BHCS_panel.png"] forState:UIControlStateNormal];
[Btn addTarget:self action:#selector(subCategoryBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
[Btn setTag:i+100];
[view addSubview:Btn];
UILabel *nameLbl=[[UILabel alloc]initWithFrame:CGRectMake(20, y_axis,248, 44)];
nameLbl.text = [[Arr objectAtIndex:i]objectForKey:#"SubCategoryName"];
nameLbl.textColor = [UIColor whiteColor];
nameLbl.backgroundColor=[UIColor clearColor];
panelTableView.separatorColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"BHCS_panel_div1.png"]];
nameLbl.font = [UIFont fontWithName:#"Helvetica" size:12.0f];
[view addSubview:nameLbl];
y_axis=y_axis+44+1.3f;
}
}

Answer 1

I have tried maximum of given answers, but at the and I generally use to go for most Generalised and ideal way as follows:
CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];

ALLLLL of the answers here are bad and you shouldn't be looping through superviews. Classic example, with iOS 7 Apple changed the tableViewCell hierarchy and your app will now crash!
Use this instead:

Updated answer
Use it like:
CGPoint hitPoint = [sender convertPoint:CGPointZero toView:self.tableView];
NSIndexPath *hitIndex = [self.tableView indexPathForRowAtPoint:hitPoint];

Answer 4

Thanks to all i slove this by using below code
NSIndexPath *indexPath = [panelTableView indexPathForCell:(UITableViewCell *)sender.superview.superview];
NSLog(#"%d",indexPath.row);

None of these answers seem like a very clean solution. The way I would implement this is by using the delegate pattern. The view controller is the cell's delegate, meaning you let the cell itself handle the button press, and it tells its delegate when the button was pressed so it can handle it however it wants.
Let's say you have a tableview where each cell represents a Person object, and when the button is pressed you want to show a profile for this person. All you need to do is this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
PersonCell *cell = [tableView dequeueReusableCellWithIdentifier:#"customTableViewCell" forIndexPath:indexPath];
cell.delegate = self;
cell.person = self.people[indexPath.row];
return cell;
}
- (void)personCell:(PersonCell *)personCell didPressButtonForPerson:(Person *)person {
[self showProfileForPerson:person];
}
Then all you need to do in your button class is add a property called buttonPressedHandler that is a block passing back an instance of Person, and when you create your button and add the target do something like this:
- (void)viewDidLoad {
[super viewDidLoad];
// do whatever whatever else you need/want to here
[self.button addTarget:self selector:#selector(handleButtonPressed) forState:UIControlStateNormal];
}
- (void)handleButtonPressed {
// Make sure this is a required delegate method, or you check that your delegate responds to this selector first...
[self.delegate personCell:self didPressButtonForPerson:self.person];
}

Answer 6

Put this code in the button's action method:
NSIndexPath *indexPath = [yourtableviewname indexPathForCell:(UITableViewCell *)sender.superview];
NSLog(#"%d",indexPath.row);

Answer 7

I suggest adding a property to your custom UITableViewCell implementation class to store the indexPath. Then, when your cellForRowAtIndexPath delegate fires in your TableViewController, set the indexPath property for that cell.
customTableViewCell.h :
#interface customTableViewCell : UITableViewCell
#property NSIndexPath *indexPath;
#end
customTableViewController configure cell:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
customTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"customTableViewCell" forIndexPath:indexPath];
// Do whatever you want with your cell
cell.indexPath = indexPath;
return cell;
}
Then you can refer to the indexPath property in your customTableViewCell by calling self.indexPath

Answer 8

You can use UITableView's indexPathForCell: method like so [tableView indexPathForCell:cell];. Good Luck!
