I have a problem to find the touch point.

I have a function `loadView()` where I set 16 tiles(16 `UIImageView`).

Then In function:

```
- (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
    // Retrieve the touch point

    UITouch *touch=[[event allTouches]anyObject];
    CGPoint point= [touch locationInView:touch.view];
    CGRect frame = [self frame];  // Error this Line
}

```

I have Used frame to identify which frame/tiles is pressed using frame-origin.

But this line:

```
CGRect frame = [self frame];

```

makes me crazy. Plz someone tell me What to do.(with explanation and why not working). Plz.
