ios本地存储（swift版）

写入数据到本地

 let filePath:String = NSHomeDirectory() + "/Documents/my.plist";
        let arr = NSMutableArray();
        //homeVC.cameraList为Array<[String:Any]>
        arr.addObjects(from: homeVC.cameraList);
         arr.write(toFile: filePath, atomically: true);

从本地取出数据

         let getArr = NSArray(contentsOfFile: filePath);

        if getArr?.count ?? 0 > 0{
               homeVC.cameraList = getArr as! Array<[String : Any]>;
        }
