Capturing Gestures over a UIWebView - uiwebview

I am trying to set up a simple iPad application that has a table view and when you select a row for that table it displays a (drilled down to) UIWebView displaying the selected web page (related to the row selected).
Once in the drilled-down-to view I want to capture EVERY touch and gesture (tap, swipe, pinch, etc) and do my own thing with them. Yes, I know this will make navigating and interacting with the web page displayed impossible, that's the idea.
I have found and played around with the Stack Overflow question that was answered by this wepage: http://mithin.in/2009/08/26/detecting-taps-and-events-on-uiwebview-the-right-way/ and I can't get gestures to work with idea.
Any suggestions would be greatly appreciated. Thanks!

UIWebView already has a lot of gestureRecognizer attached to them. It might be a good idea to remove all those gesture recognizer before adding yours, as a testing unit.
If your gesture recognizer works, that means you could basically store the default recognizer in a private array and as soon as you want to give normal behavior to your webview again, you "reset" the UIWebView recognizer

How to display a webview in full screen (autofit)

I am developing a webview app.
I need that the webview covers all the content (all the space available!) but I can't get to this...
I've tried several ways but stil don't understand how to tell the webview to autofit depending on the screen.
Here is my situation now:
And this if I rotate the device
I guess this means that I'm not working in the right way, eh ? Can anybody lead me to this right?
thank you
Add this 4 constraint like this for your webView.

WPF - Flahing button with a icon on it

How do I place two icons on a WPF button, one in the middle (static icon) and one on the top left (based on a condition)? Also need to Flash the same WPF Button based on a condition?
(While flasing it switches between two background colors, the icons remains same).
Not sure if anyone will want to help you develop super annoying flashing advertising ad style buttons :)
But to point you in the right direction the answer is in learning how to override default control template for the button then for flashing - work on Animation. Once you try that and encounter problems, then post your code and someone will help.
P.S. 'Adam Nathan's WPF Unleashed' is a good start. Good luck!

What is the alternative to putting UIWebView inside UIScrollView

I have gotten UIWebView inside UIScrollView to work, so far anyways, and I have just seen mention on Apple's site that doing so is not advised.
So OK, what's the alternative? I need to display web pages, and I need them to be scrollable, such that if the user swipes leftward then an entirely different page appears coming in from the right. And a reverse situation with swiping rightward.
How is that done without putting UIWebView inside UIScrollView?
Thanks.
Well, you need the UIWebView, which has indeed many features of a UIScrollView, to be able to scroll not only up and down, but also to left and right.
Also, scrolling with two fingers is a no-go, for scrollable elements within a web page, such as textareas can only be scrolled with two fingers.
Three fingers is also not so good because that's not convenient for people with thick fingers...
So my suggestion is that you add a UIGestureRecognizer to your UIWebView and look out for a swipe gesture. Then handle the switching of pages accordingly with animations.

How can I create scrolling areas like the ones on stackoverflow?

I'm currently working on a flash project, which will use multiple scroll areas.
I'm trying to find out how to create a scroll area like I see on stackoverflow, and make it function similarly.
Whenever someone posts their lines of code to stackoverflow, the scroll area scrollbar looks exactly like the scrollbar in the web browser, and is able to be scrolled with the mousewheel smoothly, without affecting the webpage scrolling.
Example: disable mouse wheel scrolling while cursor over flex app?
Could anyone please explain to me how I can do this in my flash project?
Thanks!!
You wouldn't need flash to do this... This is accomplished using CSS. You would just need to put the portion you wanted to function like that in a div (or any HTML container for that matter) and then define such properties as min-height, max-height, min-width, max-width, overflow, etc. I think there's one that determines the presence of the scroll bars but I don't remember what it is for sure. Very easy to do this and flash would be a bit of overkill.

android - UI like sliding down notification bar

I want to develop a panel with animation same as notification panel. I mean to say the notification panel is a cool control where you grab and slide down the notification bar and see all the notifications.
Actually, I am having 2 UI , 1st should be shown with Button at top, when user click on that button, the 2nd UI with listview items should be slide down same as notification panel and again when user click or drag the 2nd UI at the top side, then 2nd UI should be become invisible. I hope i made clear my question.
From Christian's answer, I am trying to use a sliding drawer that will display a
list of options. I need this to expand over the current ListView on the page.
So if anybody know how to implement such layout or UI with sliding down animation then please share it.
Please suggest how to build with such control or layout? any ideas or suggestions
Thanx
Have you tried the SlidingDrawer widget?
Paresh I found a solution in this post about sliding drawers.
android misc widgets has it implemented , though it still has some flaws but it will definitely prove helpful.
Though in the same SO post CommonsWare has quoted :
...
You similarly cannot make a
SlidingDrawer that descends from the
top.
Good Luck.
You can use SlidingTray from: http://aniqroid.sileria.com to make this happen
http://aniqroid.sileria.com/doc/api/com/sileria/android/view/SlidingTray.html
Alternatively you can also use a custom PopupWindow class which is part of Android API.
