Iphone: UIWebview and double taps
- by Eyal
I would like to trap a double tap event in a UIWebView. I have derived a class from UIWebController. When I double tap it seams that the UIWebController itself is responding to my double taps instead of my class. The weird thing is that when I change the inheritance to inherit from UIView everything works just fine.
Below are snippets from my code which is supposed to invoke a pop-up when double tapped.
In the init function:
//Setup action for double tap
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)];
tap.numberOfTapsRequired = 2;
[super addGestureRecognizer:tap];
[tap release];
And Also:
- (void)handleDoubleTap:(UIGestureRecognizer *)gestureRecognizer
{
UIAlertView *someError = [[UIAlertView alloc] initWithTitle: @"Network error" message: @"Hello" delegate: self cancelButtonTitle: @"Ok" otherButtonTitles: nil];
[someError show];
[someError release];
//[[NSNotificationCenter defaultCenter] postNotificationName:NOTIFICATION_FLIP_TO_PAGE_VIEW object:nil];
}
