如何捕获按TabViewCell的事件？

Question

I have question for you ... I have UITableView and I want to catch event when user press the cell in order to change the color of label that I insert into UITableViewCell. The moment when user touch the cell.

1. tableView:willSelectRowAtIndexPath:
2. tableView:didSelectRowAtIndexPath:

functions didn't help me ...

Who have any suggestion ? Thanks a lot for help !!!

Answer 1

Subclass the UITableViewCell and override the UIResponder with these:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event;

Then you will have 2 separated events when press and when release.

Answer 2

If you want to change the color of a UILabel inside a UITableViewCell when it's selected, you don't have to do any sort of event catching. You just have to change the highlightedTextColor property of the UILabel . The default is usually white.

Answer 3

Did you set the delegate of the tableView?

Did your class conform to the UITableViewDelegate protocol?

Answer 4

Confirm With UITableViewDelegate protocol and implement the methods which you mention,

Do'nt forget to set the delegate property of your UITableView .

myTableView.delegate = self;
