Answer 1

If you want to detect a touch on the UITableViewCell you don't really need to detect touch events. In your UITableViewController subclass, you need to implement the following delegate method:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;

Then you modify the image of the table cell for the selected index path.

Answer 2

You probably need to set myImageView.userInteractionEnabled = YES; .

Answer 3

In one of my projects I needed any tap on the tableView to dismiss the keyboard so the underlying tableView would show. Since a UITableView is really a UIScrollView, it will respond to the scrollView delegate methods. Using these 2 methods will dismiss if either the user taps on a cell or scrolls the tableView at all:

IMPORTANT: Make sure you implement the UIScrollViewDelegate in your .h file as well as the UITableViewDelegate and UITableViewDataSourceDelegate!!!

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    //remove keyboard if table row is clicked
    if ([self.firstName isFirstResponder] || [self.lastName isFirstResponder]) {
        [tableView deselectRowAtIndexPath:indexPath animated:NO];
        [self.firstName resignFirstResponder]; 
        [self.lastName resignFirstResponder]; 
    }
}

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    //remove keyboard if table scrolls
    if ([self.firstName isFirstResponder] || [self.lastName isFirstResponder]) {
        [self.firstName resignFirstResponder]; 
        [self.lastName resignFirstResponder]; 
    }
}
