相机权限

import Photos

func CameraQX(successCallBack: @escaping ((Bool) -> Void)) {

let authStatus = AVCaptureDevice.authorizationStatus(for: AVMediaType.video)
        
if (authStatus == .authorized) { /****已授权，可以打开相机****/
    successCallBack(true)
}
    
else if (authStatus == .denied) {
    
    let alertV = UIAlertView.init(title: "提示", message: "请去-> [设置 - 隐私 - 相机] 打开访问开关", delegate: nil, cancelButtonTitle: nil, otherButtonTitles: "确定")
    alertV.show()
    successCallBack(false)
}
    
else if (authStatus == .restricted) {//相机权限受限
    let alertV = UIAlertView.init(title: "提示", message: "相机权限受限", delegate: nil, cancelButtonTitle: nil, otherButtonTitles: "确定")
    alertV.show()
    successCallBack(false)
}
    
else if (authStatus == .notDetermined) {//首次 使用
    AVCaptureDevice.requestAccess(for: .video, completionHandler: { (statusFirst) in
        if statusFirst {
            //用户首次允许
            successCallBack(true)
        } else {
            //用户首次拒接
            successCallBack(false)
        }
