ALAuthorizationStatusRestricted, // This application is not authorized to access photo data.
// The user cannot change this application’s status, possibly due to active restrictions
// such as parental controls being in place.
ALAuthorizationStatusDenied, // User has explicitly denied this application access to photos data.
ALAuthorizationStatusAuthorized // User has authorized this application to access photos data.

iOS7之前都可以访问相机，iOS7之后访问相机有权限设置。
打开设置
2.拉到底端找一个应用，微信举例。
3.看到相机可以开启和关闭权限。
一般新下载的应用在点开第一会有提示要不要开启相机权限，如果没有开启，想开启的时候进行以下步骤就可以了。
打开设置
找到想查看的软件
看到相机打开后面的按钮（绿色为打开）
