import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate,
UINavigationControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
}
//拍照
@IBAction func fromPhotograph(sender: AnyObject) {
if UIImagePickerController.isSourceTypeAvailable(.Camera){
//创建图片控制器
let picker = UIImagePickerController()
//设置代理
picker.delegate = self
//设置来源
picker.sourceType = UIImagePickerControllerSourceType.Camera
//允许编辑
picker.allowsEditing = true
//打开相机
self.presentViewController(picker, animated: true, completion: { () -> Void in
})
}else{
println("找不到相机")
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}

2，调用前置，后置摄像头
相机默认使用后置摄像头，可以设置UIImagePickerControllerCameraDevice类型来使用前置摄像头或后置摄像头。
像iTouch设备不具备前置摄像头，我们可以事先判断下是否支持前置。

//如果有前置摄像头则调用前置摄像头if UIImagePickerController.isCameraDeviceAvailable(UIImagePickerControllerCameraDevice.Front){
picker.cameraDevice = UIImagePickerControllerCameraDevice.Front

3，设置闪光灯
通过cameraFlashMode属性可以设置闪光灯：开启/关闭/自动
