在iOS 8/9中根据设备方向更改Viewcontroller [英] Change Viewcontroller based on device orientation in iOS 8/9

问题描述

在iOS 8/9中基于设备方向在两个视图控制器之间进行区分的首选方法是什么？我想建立一个横向展示的乐器。在肖像中，我想显示应用程序的设置。

What is the preferred way of segueying between two viewcontrollers based on device orientation in iOS 8/9? I want to build an instrument that is shown in landscape. In portrait i want to show the settings of the App.

推荐答案

在didFinishLaunchingWithOptions函数中的AppDelegate.swift中我放了：

In AppDelegate.swift inside the "didFinishLaunchingWithOptions" function I put:

NSNotificationCenter.defaultCenter().addObserver(self, selector: "rotated", name: UIDeviceOrientationDidChangeNotification, object: nil)

然后在AppDelegate类中，放入以下函数：

And then inside the AppDelegate class, put the following function:

func rotated(){
    if(UIDeviceOrientationIsLandscape(UIDevice.currentDevice().orientation){            
        println("landscape")
    }

    if(UIDeviceOrientationIsPortrait(UIDevice.currentDevice().orientation)){
        println("Portrait")
    }
}

或者你可以使用这个：

override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
    if UIDevice.currentDevice().orientation.isLandscape.boolValue {
        println("landscape")
    } else {
        println("portraight")
    }
}
