you can use UITapGestureRecognizer added to the UIImageView via addGestureRecognizer snippets: UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(bannerTapped:)]; singleTap.numberOfTapsRequired = 1; singleTap.numberOfTouchesRequired = 1; [iv addGestureRecognizer:singleTap]; [iv setUserInteractionEnabled:YES]; and – (void)bannerTapped:(UIGestureRecognizer *)gestureRecognizer { NSLog(@”%@”, [gestureRecognizer view]); }
It sounds to me like you want to have a touch-screen-friendly option, to cover the following scenarios: iPhone-like devices: small screen, touch only Small screens, no touch (you didn’t mention this one) Large screens, no touch (i.e. conventional computers) Touch-screen-enabled large screens such as iPad, notebooks/pcs with touch screens. For case 1 and 2 you … Read more
Kinda late, but you need to access the original event, not the jQuery massaged one. Also, since these are multi-touch events, other changes need to be made: $(‘#box’).live(‘touchstart’, function(e) { var xPos = e.originalEvent.touches[0].pageX; }); If you want other fingers, you can find them in other indices of the touches list. UPDATE FOR NEWER JQUERY: … Read more
I seek a way to handle touches that do not start on UI elements in Unity Engine …But if the touch down event is on any of the UI elements it shall be handled by that UI element instead of the map. The IsPointerOverGameObject function is used to simplify this. If it returns false, do … Read more
Try the following. Write a class which derives from the Overlay class and override the onTap() method. Then you can add your overlay to the your MapView. A GeoPoint object, which represents the position of you tap, is passed to the onTap() method when you tab somewhere on the map.
I’ve done it. Thanks to incanus and Anna! Basically I add a TapGestureRecognizer to the MapView, convert the point tapped to map coordinates, go through my overlays and check with CGPathContainsPoint. Adding TapGestureRecognizer. I did that trick of adding a second double tap gesture, so that the single tap gesture isn’t fired when doing a … Read more
mWebView.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { return true; } }); Disables all touch events on a WebView because the touch listener is executed before the default touch behavior of the WebView. By returning true the event is consumed and isn’t propagated to the WebView. Using android:clickable=”false” does not disable touch … Read more
I had some issues in Ipad and solved it with two events var ts; $(document).bind(‘touchstart’, function (e){ ts = e.originalEvent.touches[0].clientY; }); $(document).bind(‘touchend’, function (e){ var te = e.originalEvent.changedTouches[0].clientY; if(ts > te+5){ slide_down(); }else if(ts < te-5){ slide_up(); } });
iPad both understands touchstart/-end and mousestart/-end. Is gets fired like this: ┌─────────────────────┬──────────────────────┬─────────────────────────┐ │Finger enters tablet │ Finger leaves tablet │ Small delay after leave │ ├─────────────────────┼──────────────────────┼─────────────────────────┤ │touchstart │ touchend │ mousedown │ │ │ │ mouseup │ └─────────────────────┴──────────────────────┴─────────────────────────┘ You have to detect if the user is on a tablet and then relay on the touch … Read more
Now some mobile browsers eliminate 300 ms click delay if you set the viewport. You don’t need to use workarounds anymore. <meta name=”viewport” content=”width=device-width, user-scalable=no”> This is currently supported Chrome for Android, Firefox for Android and Safari for iOS However on iOS Safari, double-tap is a scroll gesture on unzoomable pages. For that reason they … Read more
