I'm calling a MFMailComposerViewController in my app and adding it as a subview to the UIView. When the user has finished with the e-mail I'm calling dismissModalViewControllerAnimated to remove it, but the app delegate no longer gets touch events and I don't know why. This only happens in OS 4.0+ though. ...
When you listen for the touch events (touchstart, touchmove, touchcancel, touchend) on a touch device like the iPad, and in your touchstart eventhandler you are invoking preventDefault(), is it possible to add or remove classes in order to change the visible appearance of the touched element? When I try to add a class at that juncture, ...
I'm currently developing a touch screen application using C# (.NET 4.0) and WPF for Windows 7. My problem is that the driver of the touch screen I have available at the moment only generates mouse events. (The manufacturer unfortunately does not provide a genuine Windows 7 driver) So, currently I'm not able to do tests properly. Is ther...

:-moz-system-metric(touch-enabled) looks like a really useful CSS selector for working on mobile sites. Unfortunately Webkit is dominant on mobile touch devices so does anyone know if there is a Webkit equivalent? (Ideally it'd be good if this was managed by CSS3 media queries) Edit: Looks like it is supported in Gecko as a media que...
On my simulator, a UITabBar appears to react to mouse clicks up to about 10 pixels above the visible bar. On the phone, it is hard to tell what is going on, but my experience has been that if I put a button right up against the tab bar, users will frequently aim for the button but end up tapping the tab bar, which can be extremely confu...
I have a UITableView that represents a list of objects, I'd like the user to touch an object, drag it onto another one (as to combine them) and seeing the two disappearing and a new one appearing. I guess that I can't do this with the standard table view editing methods (a row cannot be dragged onto another one, am I right?). Shall I wri...
I am loading some sequence of pages while the user swipes/flings on the webview, using the animation effect of the viewflipper - to bring that iphone transition effect. I have two webviews added to a viewflipper. Added setOnTouchListener to both the webviews and using gesture detector for fling. After detecting the fling direction, I ...

I have an UIViewController which contains a UITableView (subclassed) and another UIView (subclassed). They are on the same hierarchy level but the UIView is added last so it is the frontmost. I overrid touchesBegan/Moved/Ended to intercept the Gestures from the top UIView: my goal is to get the selected UITableViewCell and, if double tap...

Hi I would like to get access to the area covered by a finger for each touch event on an Android. Every touch event will result in a coordinate pair X and Y independent of how big the finger and consequently the touch area is that triggered the event. I was wondering if there is a way to get the area data which triggered the touch eve...

Hi, I'm building a javascript-powered gallery on the iPad that can display both images and video. To browse the gallery, you can swipe left or right (similar to the iPad's Photo application). However, none of my touch events work when swiping over a <video> element. It seems to take over my touch events, even on elements that may have a...
I'm working to build a web app that uses the WebKit Touch Events JS API. How can I QA this app on my mac with touch events, and not be forced to swap between developing on a mac and testing on an iPhone. Ideas? ...
I am having issues with UIButton with the iPhone SDK. I've determined that when I have a UIButton held down when the parent is removed (and the uibutton subsequently removed), I get some strange behavior. In my case, the app stops receiving any input whatsoever, as if the cleaned up held-down button has hijacked the input system someho...
I'm using the following to capture Touch Events on an Iphone. document.addEventListener('touchmove', function(event) { event.preventDefault(); var touch = event.touches[0]; $('#touchPosition').text("Touch x:" + touch.pageX + ", y:" + touch.pageY); }, false); Strangely, I'm finding that the positions are wrong...
