[ SWIFT ] - FUNC - 判斷裝置與取得目前裝置 方向 ＆ SIZE

判斷裝置：traitCollection

if( self.traitCollection.userInterfaceIdiom == UIUserInterfaceIdiom.Pad)

        {NSLog("裝置為iPad")}

if( self.traitCollection.userInterfaceIdiom == UIUserInterfaceIdiom.Phone)

        {NSLog("裝置為iPhone")}

判斷裝置目前螢幕方向（當裝置方向改變時呼叫）：willTransitionToTraitCollection

override func willTransitionToTraitCollection(newCollection: UITraitCollection, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {

        

        super.willTransitionToTraitCollection(newCollection, withTransitionCoordinator: coordinator)

        if( newCollection.horizontalSizeClass == UIUserInterfaceSizeClass.Compact)

        {

          NSLog("Compact Width")

        }

        

        if( newCollection.horizontalSizeClass == UIUserInterfaceSizeClass.Regular)

        {

            NSLog("Regular Width")

        }

        

        if( newCollection.verticalSizeClass == UIUserInterfaceSizeClass.Compact)

        {

            NSLog("Compact Height")

        }

        

        if( newCollection.verticalSizeClass == UIUserInterfaceSizeClass.Regular)

        {

            NSLog("Regular Height")

        }

判斷裝置最後方向與螢幕解析度：
viewWillTransitionToSize:當view得尺寸改變時呼叫。

 override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {

        super.viewWillTransitionToSize(size, withTransitionCoordinator: coordinator)

        

        var orientation:UIDeviceOrientation = UIDevice.currentDevice().orientation

        if (orientation == UIDeviceOrientation.LandscapeLeft)

        {

        NSLog("橫向，頂端再左側")

        }

        

        if (orientation == UIDeviceOrientation.LandscapeRight)

        {

            NSLog("橫向，頂端再右側")

        }

        

        if (orientation == UIDeviceOrientation.Portrait)

        {

            NSLog("直向")

        }

        

        if (orientation == UIDeviceOrientation.PortraitUpsideDown)

        {

            NSLog("直向但上下顛倒")

        }

        

        if (orientation == UIDeviceOrientation.Unknown)

        {

            NSLog("方向未知")

        }

        

        var bounds: CGRect = UIScreen.mainScreen().bounds

        var screenWidth : CGFloat = bounds.width;

        var screenHeight : CGFloat = bounds.height;

        NSLog("解析度為：%fx%f",Float(screenWidth),Float(screenHeight))

    }
