How can I select image through touch on tableviewcell - ios

Question

I am new to app development. In my app when I click on my table view cell, the cell is selected and didSelectRowAtIndexPath method is triggered irrespective of whether I clicked on image or cell. I want the image to be selected when I click on the image, not the cell. Thanks in advance.

Answer 1

Add UITapGestureRecognizer on your image view, and if you not want cell selection then off table view cell selection . on Tap function on image do what you want.

Answer 2

In your cellForRowAtIndexPath method, add a custom UIButton and assign the image as background image of the button. Then add target to the button and handle your code inside the button target method
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"CellIdentifier"];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"CellIdentifier"];
UIButton *imageButton = [[UIButton alloc] initWithFrame:<Give the frame you want>];
[imageButton setBackgroundImage:<your image> forState:UIControlStateNormal];
[imageButton addTarget:self action:#selector(imageButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:imageButton];
}
return cell;
}
Here the best method is to create a custom UITableViewCell which have imageButton as an instance variable instead of creating it inside cellForRowAtIndexPath method. Now in the imageButtonClicked method
-(void)imageButtonClicked:(UIButton *)sender {
UIImage *image = sender.currentBackgroundImage;
//Do the logic what you want here
}
Please give the frame of the button so that it is placed at the position you want.
I haven't tried out this code. If sender.currentBackgroundImage is not giving you the image, then create a custom button extending from UIButton. The custom button should have a UIImage variable as an instance variable. Assign the variable to the image you want when it is initialized(in cellForRowAtIndexPath method). And then you can access the image in the button target method
