首先，我是 iOS 新手，处于开发的早期阶段，但想从正确的方向开始，我做了一些基本的 iOS 教程并完成了 html/c++ 开发。我们有两个成员制作这个应用程序，他将负责 UI 和本地数据存储，而我需要将数据从 iOS 上传到网站。会有一个本地数据库快速记录，我想做两种类型的上传。
我正在寻找我应该使用哪些方法、数据库和 API。我一直在环顾四周，人们使用不同的 API，我不确定什么最适合我的应用程序。如果您有教程的链接，也将不胜感激。环顾四周，我应该使用 sql（在电话和 Web 服务器上）、php 和 post。谢谢。
我编写了一个自定义类，它使用 AFNetworking 来处理网络请求。我已经将它与基于 PHP 和 .NET 的 Web 服务一起使用。由于请求使用 POST 参数，因此非常灵活。
这是课程：

一个示例调用将类似于：
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
@"GetMeetingRooms", @"Command",
nil];
[NetworkClient processURLRequestWithURL:nil andParams:params block:^(id obj) {
// Check to make sure we got back a response message (NSArray of NSDictionaries in JSON format
if ([obj isKindOfClass:[NSArray class]]) {
NSArray *response = (NSArray *)obj;
// So dome work here with the response here
}
}];
