How to Disable 4 Finger Gestures on iPad

How can I prevent iPad multitasking gestures on my website

The gestures occur at the OS level, so they can’t be interfered with by JavaScript.

More generally, the multitasking gestures are unreachable from anything in the app layer, so JavaScript would be unable to get out of the browser to disable them. (Even if you wrote a native app, you can’t work around them yet.)

I’d also argue that trying to interfere with the gestures, which the user has enabled and expects to work universally, is poor practice, and should be avoided.

Can I disable the home screen pinch in iOS?

You mean on the iPad? The pinch gestures are all under the setting...

Settings - General - Multitasking Gestures.

Just turn that off and it removes the home screen pinch.

Disable gesture recognizer iOS

The four- and five- finger gestures are not officially part of iOS, and may never be.

Though it would be best to figure out an alternative, you should be able to use these gestures for now and not fear conflicts (save on the iPads of developers who have specifically turned on this feature, whose users know that said features may conflict with apps.)

Yes, you can disable that behavior. Set the presentsWithGesture property of the split view controller to NO to disable the swiping gesture.
