Getting row of UITableView cell on button press
(10 answers)
Closed 9 years ago.
I have a custom method to detect a tap on a cell's image. I want to also find the index path of the image's correlating cell, and use it within the function. Here is what I am using:
CellforRowAtIndexPath:
UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(cellImageTapped:)];
tapped.numberOfTapsRequired = 1;
[cell.imageView addGestureRecognizer:tapped];
method im trying to get the index path at:
-(void)cellImageTapped:(id)sender {
if(videoArray.count > 0){
Video *currentVideo = [videoArray objectAtIndex:INDEX_PATH_OF_CELL_IMAGE];
//do some stuff
}
}
I have no idea how to pass the index path. Any ideas?

Answer 1

Simple way:
Get the point of touch
Then get index path of cell at point
The code is:
-(void)cellImageTapped:(id)sender {
UITapGestureRecognizer *tap = (UITapGestureRecognizer *)sender;
CGPoint point = [tap locationInView:theTableView];
NSIndexPath *theIndexPath = [theTableView indexPathForRowAtPoint:point];
if(videoArray.count > 0){
Video *currentVideo = [videoArray objectAtIndex:theIndexPath];
//do some stuff
}
}

Answer 2

I would recommend this way to fetch indexPath of cell which has custom subview - (compatible with iOS 7 as well as all previous versions)
- (void)cellImageTapped:(UIGestureRecognizer *)gestureRecognizer
{
UIView *parentCell = gestureRecognizer.view.superview;
while (![parentCell isKindOfClass:[UITableViewCell class]]) { // iOS 7 onwards the table cell hierachy has changed.
parentCell = parentCell.superview;
}
UIView *parentView = parentCell.superview;
while (![parentView isKindOfClass:[UITableView class]]) { // iOS 7 onwards the table cell hierachy has changed.
parentView = parentView.superview;
}
UITableView *tableView = (UITableView *)parentView;
NSIndexPath *indexPath = [tableView indexPathForCell:(UITableViewCell *)parentCell];
NSLog(#"indexPath = %#", indexPath);
}

Answer 3

Add a tag to the UIImageView in your UITableViewDataSource's tableView:cellForRowAtIndexPath: method.
cell.imageView.tag = indexPath.row;

Answer 4

I ended up using the sender's view's tag. Hopefully this will help someone, as I wasted an hour finding the answer.
-(void)cellImageTapped:(id)sender {
UITapGestureRecognizer *gesture = (UITapGestureRecognizer *) sender;
if(videoArray.count > 0){
NSInteger datIndex = gesture.view.tag;
Video *currentVideo = [videoArray objectAtIndex:datIndex];
}
}

Answer 5

Use the delegate method didSelectRowAtIndexPath: method
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self cellImageTapped:indexPath];
}
Then you can pass the index to a function i.e.
-(void)cellImageTapped:(NSIndexPath *)indexPath
{
Video *currentVideo = [videoArray objectAtIndex:indexPath.row];
}
