gesture-recognition

Got a gesture related problem. I implemented UISwipeGestureRecognizer to get swipe left and right events and that is working fine. However the problem I'm facing is that the UISlider's I have in the same view are not playing nice. The sliding motion of the sliders is being mistaken as a swipe left/right. Any one experienced this problem before, got any ideas how to correct it? Many thanks. Here is the code contained within the view controller: - (void)viewDidLoad { [super viewDidLoad]; //Setup handling of LEFT and RIGHT swipes UISwipeGestureRecognizer *recognizer; recognizer = [

Is there a bug in the 3.0 SDK that disables real-time zooming and intercepting the zoom-in gesture for the MKMapView? I have some real simple code so I can detect tap events, but there are two problems: zoom-in gesture is always interpreted as a zoom-out none of the zoom gestures update the Map's view in realtime. In hitTest, if I return the "map" view, the MKMapView functionality works great, but I don't get the opportunity to intercept the events. Any ideas? MyMapView.h: @interface MyMapView : MKMapView { UIView *map; } MyMapView.m: - (id)initWithFrame:(CGRect)frame { if (![super

I would like to trigger a touch event like this: First the finger is touch down at the (0,50%) of the screen and slide to the (50%,50%) of the screen, and exit (move the finger off the screen) I have found some thing like this: MotionEvent event = MotionEvent.obtain(downTime, eventTime, action, x, y, pressure, size, metaState, xPrecision, yPrecision, deviceId, edgeFlags); onTouchEvent(event); However, how to emulate the above case? Do I need to create 2 event ? onTouchDown , onMove etc.... ? Thanks for helping. bstar55 // Obtain MotionEvent object long downTime = SystemClock.uptimeMillis();

In my iPhone app, I require to recognize the swipe gesture made by the user on the view. I want the swipe gestures to be recognized and perform a function on swipe. I need that the view should horizontally slide and show another view as a user makes a swipe gesture. What needs to be done? How do I recognize it? Use the UISwipeGestureRecognizer . Not much else to say really, gesture recognizers are easy. There are WWDC10 videos on the subject even. Sessions 120 and 121. :) If You know how it works, but still need a quick example, here it is! (it will become handy at least for me, when I will

Sounds simple .. Hold the Trackpad, move the finger, release .. But somehow swipe is not being triggered (pan is triggered instead) UISwipeGestureRecognizer *swipeGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:v action:@selector(handleSwipe:)]; swipeGesture.direction= UISwipeGestureRecognizerDirectionUp; [v addGestureRecognizer:swipeGesture]; Pan is recognized by the above sequence instead. UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:v action:@selector(handlePan:)]; [v addGestureRecognizer: panGesture]; If pan is commented, swipe is

A common way to dismiss a modal is to swipe down - How do we allows the user to drag the modal down, if it's far enough, the modal's dismissed, otherwise it animates back to the original position? For example, we can find this used on the Twitter app's photo views, or Snapchat's "discover" mode. Similar threads point out that we can use a UISwipeGestureRecognizer and [self dismissViewControllerAnimated...] to dismiss a modal VC when a user swipes down. But this only handles a single swipe, not letting the user drag the modal around. Robert Chen I just created a tutorial for interactively
