如何在AS3中使用iOS相机？

Question

Can you use the camera of an iOS device in an AS3 app? If so, how?

Answer 1

Yep it's really easy, there are many ways to access the camera in AS3.

Firstly, the same way as you access the camera in normal AS3 applications:

var camera:Camera = Camera.getCamera();
var video=new Video();
video.attachCamera(camera);
this.addChild(video);

This will display the camera in the current display object.

You can also ask for images from the Camera roll using the CameraRoll class:

import flash.media.CameraRoll;
var cameraRoll:CameraRoll = new CameraRoll();

if(CameraRoll.supportsBrowseForImage) 
{
    cameraRoll.addEventListener(MediaEvent.SELECT, imageSelected); 
    cameraRoll.addEventListener(Event.CANCEL, browseCancelled); 
    cameraRoll.addEventListener(ErrorEvent.ERROR, mediaError); 

    // Ask the user to select an image
    cameraRoll.browseForImage(); 
}

You can use the native "camera" application to take a photo:

import flash.media.CameraUI;

var cameraUI:CameraUI = new CameraUI();

if (CameraUI.isSupported ) 
{
    cameraUI.addEventListener(MediaEvent.COMPLETE, imageSelected); 
    cameraUI.addEventListener(Event.CANCEL, browseCancelled); 
    cameraUI.addEventListener(ErrorEvent.ERROR, mediaError); 

    cameraUI.launch(MediaType.IMAGE); 
}

Hope that points you in the right direction.
