二、填入下列程式碼,就可以了。
let dirPaths = NSSearchPathForDirectoriesInDomains(.documentDirectory,.userDomainMask, true) let docsDir:String! = dirPaths[0] let destPath = (docsDir as NSString).appendingPathComponent("/db.sqlite")//這裡填入你的.sqlite let fileMgr = FileManager.default if let path = Bundle.main.path(forResource: "db", ofType:"sqlite") { if !fileMgr.fileExists(atPath: destPath)//如果db不存在,那就直接複製一份 { do { try fileMgr.copyItem(atPath: path, toPath: destPath) print("success")// } catch let error as NSError { print(error.localizedDescription) } }else{ print(".sqlite已存在")// } }
