Swift PNG圖片保存方向錯誤如果在保存之前使用圖像，那是正常的。但是，如果我保存并以后使用，則需要旋轉(zhuǎn)90度。我如何確保它不會橫向保存？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!)                 }         })     }
