import UIKit
class ViewController : UIViewController , UIImagePickerControllerDelegate ottom:auto!important; float:none!important; height:auto!important; left:auto!important; line-height:1.5em!important; margin:0px!important; overflow:visible!important; padding:1px 0px!important; position:static!important; right:auto!important; top:auto!important; vertical-align:baseline!important; width:auto!important; font-family:Consolas,
UINavigationControllerDelegate {
override func viewDidLoad() {
super .viewDidLoad()
}
//拍照
@IBAction 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 ottom:auto!important; float:none!important; height:auto!important; left:auto!important; line-height:1.5em!important; margin:0px!important; overflow:visible!important; padding:1px 0px!important; position:static!important; right:auto!important; top:auto!important; vertical-align:baseline!important; width:auto!important; font-family:Consolas,completion: { () -> Void in
})
} else {
println ( "找不到相机" )
}
}
didReceiveMemoryWarning() {
.didReceiveMemoryWarning()
}
}

2,调用前置,后置摄像头
相机认使用后置摄像头,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。
4
//如果有前置摄像头则调用前置摄像头
.isCameraDeviceAvailable( UIImagePickerControllerCameraDevice Front ){
picker.cameraDevice = 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
2
//开启闪光灯
picker.cameraFlashMode = UIImagePickerControllerCameraFlashMode On
