On iOS, you can configure your notifications on a per app basis to appear in different ways. One type of notification drops down in a thin box from the top of the screen. Occasionally, this box can get in the way. If you’re typing a web address for example, you might think that you have to wait for the box to disappear to continue your typing. You can actually dismiss the box.
To dimiss the box, simply give it a quick tug with your finger – tap and hold, drag it down very slightly, and then release. Poof – the box goes away. I never knew this, until hearing about it on iFive for the iPhone, on the TWiT network. If you have any quick iOS tips, share them in the comments.
