/**
注意点: 1.看 GIF 效果图.
2.看连线视图的效果图.
3.看实现代码(直接复制实现效果).
4.此 dome 必须使用真机才可以测试,模拟器是不支持打开照相机的.
5.在 info.plist 要配置key如图4.
6.如果是4S 手机 可以不加这些 key
7.详情请看: http://blog.csdn.net/shihuboke/article/details/77150958

/**
注意点:在 info.plist 里面加 key.
1.NSCameraUsageDescription ->相机
2.NSMicrophoneUsageDescription ->麦克风
3.NSCameraUsageDescription ->相机
