Question: As part of the following method, i can ask recorgnier object of type UISwipeGestureRecognizer\*

```
- (void) handleSwipeFrom:(UISwipeGestureRecognizer*)recognizer

```

About its current location

```
CGPoint currentLocation = [recognizer locationInView:self];

```

According to [documentation](http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UITouch_Class/Reference/Reference.html), i should also be able to get

```
CGPoint previousLocation = [recognizer previousLocationInView:self];

```

This method, however, is not available. What am i missing please?

Answer: 
You can have your users download and install [Google Chrome Frame](http://www.google.com/chromeframe), then add this meta tag to your page head per the [Chrome Frame developer guide](http://www.chromium.org/developers/how-tos/chrome-frame-getting-started):

```
<meta http-equiv="X-UA-Compatible" content="chrome=1">

```

Of course, this requires user action. You can't control what browser your users use, nor can you force a certain browser to act like another browser through your own code alone.
Nope. IE sucks because it sucks. Closest you get is something like [IE7.js](http://code.google.com/p/ie7-js/) but it comes with limitations and drawbacks. It can't for example magically give IE full SVG or WebGL support but it can give IE better CSS selector support and fix some bugs.
