[PHP]利用XAMPP搭建本地服务器, 然后利用iOS客户端上传数据到本地服务器中(四. iOS端代码实现)

Posted 2020-06-21 M_Lee

一.安装XAMPP   http://www.cnblogs.com/lidongxu/p/5256330.html

二. 配置mysql  http://www.cnblogs.com/lidongxu/p/5256515.html

三. php端代码编写    http://www.cnblogs.com/lidongxu/p/5267727.html

然后, 那么我们来看看ios端代码如何实现.

1. ViewContrller.m (主要类) 可能里面用到了自己定义的类LoginView  请去GitHub  https://github.com/lidongxuwork/iOS-to-PHP  上下载源代码(顺路给个星哈, 谢谢!!!)

注意: 你可能运行的时候, 遇到这个问题 failed to open stream: No such file or directory 

1. 

解决方法: 在本地服务器路径文件夹下建立文件夹 download2

错误2: 

没有权限 我们就给权限被 哈哈哈哈

然后回车 就可以啦.   然后回到Xcode 重新运行应该就没问题啦!!
