【環境：xCode4.3.2】
說明：其實從xcode中可以看到，但可以從這份文件當中看出，UIDevice可以替我們做什麼事情，包含
UIDeviceOrientation;//旋轉
UIDeviceBatteryState;//電池
UIUserInterfaceIdiom;//裝置(ipad ,iphone)版本判定
你可以抓出一些資訊，像是
name; // e.g. "My iPhone"
model; // e.g. @"iPhone", @"iPod touch"
localizedModel; // localized version of model
systemName; // e.g. @"iOS"
systemVersion; // e.g. @"4.0"
orientation; // return current device orientation. this will return UIDeviceOrientationUnknown unless device orientation notifications are being generated.
uniqueIdentifier __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_NA,__MAC_NA,__IPHONE_2_0,__IPHONE_5_0); // a string unique to each device based on various hardware info.
