How to identify device using flash actionscript3?

How 开发者_JAVA技巧can I get to know that the device is iphone or ipad using actionscript3.0?

Check out the Capabilities class: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/system/Capabilities.html

There's no 100% method to test if something is a specific device (Adobe say to not do it), mainly because you can end up with a ball of spaghetti code that's not future proof (e.g. the resolution/dpi roughly doubled between the iPhone 3GS and the iPhone 4, and who can say what the iPhone 5/6 etc will have).

What you could use are cpuArchitecture, manufacturer, os, pixelAspectRatio, screenDPI, screenResolutionX, screenResolutionY and touchscreenType to help try and figure it out.

There's also ContextMenu.isSupported as the context menu (what shows when you right-click on a swf) doesn't show up on smart phones or tablets (no right-click)
