Swift PNG图片保存方向错误

如果在保存之前使用图像，那是正常的。但是，如果我保存并以后使用，则需要旋转90度。我如何确保它不会横向保存？

func saveEvent(_ center1: CLLocation, title2: String, imagePicked1: UIImage)
    {
        let data = UIImagePNGRepresentation(imagePicked1);///        let url = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(NSUUID().uuidString+".dat")
        do {
            try data!.write(to: url!, options: [])
        } catch let e as NSError {
            print("Error! \(e)");
            return
        }
        let image11 = CKAsset(fileURL: url!)

        self.eventRecord.setObject(image11 as CKAsset, forKey: "Picture")
        let publicData = CKContainer.default().publicCloudDatabase
            publicData.save(self.eventRecord, completionHandler: { record, error in
                if error == nil
                {
                    print("Image saved")
                }else{
                    print(error!)
                }
        })
    }
