How to stop an app update on an iPhone?

I was using my friend's iPhone, and saw he had a lot of app updates that weren't started, somewhere around 30. I keep my phone updated a lot, so I figured I would get them started for him. Well, we lost internet, and so they all stopped, and now, none of them are moving anywhere and he can't get on a bunch of his apps. Is there a way to cancel the updates so it will go back to normal? I know how to on the android system, but not on iphone.

Hold down the app and there will be a small 'x' icon in a circle at the top right of the app logo, use that, or you could always restart the phone, this would mean plugging it into a computer though, to restart the phone hold down the menu button and the power button for about 5 seconds. Hope i helped
