Xcode：从iOS TextField向远程数据库发送数据的最简单方法 [英] Xcode: Easiest Way To Send Data From iOS TextField For Example To A Remote Database

问题描述

我目前在HostGator.com上有一个在线网络托管的MySQL数据库，该数据库目前存储用于我的服务的用户注册。目前，在该数据库中存储信息的唯一方法是从我在网站上的在线表单。

I currently have an online web hosted MySQL database with HostGator.com that currently stores user sign ups for a service of mine. Currently, the only way to store information in that database is from my online form on a website.

我的目标是通过使用文本字段等在iOS应用程序上复制该表单。我需要帮助搞清楚的是，如何从用户那里获取数据输入iOS应用程序，并将该信息发送到MySQL数据库。从我发现的，没有办法从iOS直接到MySQL，所以我也需要使用PHP。但是，如何将这些数据从iOS应用程序获取到PHP，以便我可以将数据从PHP发送到MySQL数据库？除此之外，我怎么能这样做，反之亦然，这意味着，如果我想，我怎样才能将消息从PHP发送回iOS应用程序？

My goal is to replicate that form on an iOS app by using textfields etc. What I need help figuring out is, how can I take the data input from the user on the iOS app, and send that information to the MySQL database. From what I found, there is no way to go from iOS straight to MySQL, so I would need to use PHP as well. However, how do I get that data from the iOS app to PHP so that I can send the data from PHP to the MySQL database? As well as, how I can I do the vice versa, meaning, if I wanted, how can I send a message back from PHP to the iOS app?

我有听说有人推荐SQLite，但这似乎是我不需要的iOS上的本地数据库。我不想在应用程序上本地存储任何内容。

I have heard people suggest SQLite, but that appears to be a local database on the iOS which I do not need. I do not want to store anything locally on the app.

谢谢

推荐答案

您只需从本机收集数据表单，然后使用NSURLRequest / NSURLConnection将数据发送到您的php服务器页面。

You can just gather the data from a native form, then use a NSURLRequest / NSURLConnection to send the data to your php server page.

//Example form with one php variable only. Use get URL argument notation to add more args.
NSString *rawStr = [NSString stringWithFormat:@"var=%@",textBox.text];
NSData *data = [rawStr dataUsingEncoding:NSUTF8StringEncoding];

NSURL *url = [NSURL URLWithString:@"http://myurl.com/script.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

[request setHTTPMethod:@"POST"];
[request setHTTPBody:data];

NSURLResponse *response;
NSError *err;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSLog(@"responseData: %@", responseData);
