Very useful in recreating browser like features, go backward on a page, etc.

You’re right, it was the iPad that broke it… I forgot which one it was!

Too bad I didn’t get your fix sooner, but I’m happy with the Gesture Recognizer solution. I honestly don’t know how to build anything to support pre 3.2 on the new XCode anyway… I get the impression Apple would just as soon you didn’t!

Thanks,

Then I tested it (for the first time) on iPad and just like you said it didn’t work – I did some debugging and after moving the code from controller’s viewDidLoad to AppDelegate’s (put after
[window addSubview:viewController.view];
[window makeKeyAndVisible];
) – it works on iPad too:

viewController.mWindow = (TapDetectingWindow *)[UIApplication sharedApplication].keyWindow;
viewController.mWindow.viewToObserve = viewController.wbvText;
viewController.mWindow.controllerThatObserves = viewController;

But I’m happy that you got it work with Gesture Recognizers. And thanks for the info – I haven’t used it before but from Apple’s doc it seems to be the better way. However it’s only available since iOS 3.2. So if one wants to support 3.0 or 3.1.x version, the technique here should be better.

Alan, I had the exact same question, so it can’t be a stupid question:) And it’s actually quite easy to break down:

1) add these after userDidTapWebView in TapDetectingWindow.h:
- (void)userTouchBegan:(id)tapPoint;
- (void)userTouchMoved:(id)tapPoint;
- (void)userTouchEnded:(id)tapPoint;

2) in sendEvent of .m, comment out
if (touch.phase != UITouchPhaseEnded)
return;
and add these:
if (touch.phase == UITouchPhaseBegan)
[self performSelector:@selector(forwardTouchBegan:) withObject:pointArray afterDelay:0.5];
else if (touch.phase == UITouchPhaseMoved)
[self performSelector:@selector(forwardTouchMoved:) withObject:pointArray afterDelay:0.5];
else if (touch.phase == UITouchPhaseEnded)
[self performSelector:@selector(forwardTouchEnded:) withObject:pointArray afterDelay:0.5];

Also add these:

- (void)forwardTouchBegan:(id)touch {
[controllerThatObserves userTouchBegan:touch];
}
- (void)forwardTouchMoved:(id)touch {
[controllerThatObserves userTouchMoved:touch];
}
- (void)forwardTouchEnded:(id)touch {
[controllerThatObserves userTouchEnded:touch];
}

Then implement the same way as you would do with touchesBegan, touchesMoved, touchesEnded:

- (void)userTouchBegan:(id)tapPoint;
- (void)userTouchMoved:(id)tapPoint;
- (void)userTouchEnded:(id)tapPoint;
in the viewcontroller that has webview.

I just went thru this and tested and it works just like other non-webview touches.

- Open MainWindow.xib in Interface builder
- In the attributes of the Window, make sure “Visible at launch” is checked.

This solved the problem for me.

Thanks for posting the article — this approach gives me a much better feeling.
