touchesBegan is not triggered
<p>I used the codes below to detect touch on the object</p>

<pre><code>- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    NSArray *allTouches = [touches allObjects];

    for (UITouch *touch in allTouches)
    {
           NSLog(@"TOUCH DETECT");

    }
}
</code></pre>

<p>but it is not triggered </p>

<p>Welcome any comment</p>
