在Objective-C中的iPhone上使用HTTP POST和GET的教程 [英] Tutorials for using HTTP POST and GET on the iPhone in Objective-C

问题描述

我下载了使用HTTP POST和GET的苹果演示程序（它们的示例应用程序有一个带有不同部分的tabbar），代码非常混乱！

有人可以给我一些示例代码或有关它的一些教程的链接？ ：）

谢谢！

解决方案

特别好：
http：/ /www.cimgf.com/2010/02/12/accessing-the-cloud-from-cocoa-touch/

  NSMutableURLRequest * request = [[NSMutableURLRequest alloc] 
 initWithURL：[NSURL 
 URLWithString：@http://www.cimgf.com/testpost.php]]; 
 
 [request setHTTPMethod：@POST]; 
 [request setValue：@text / xml
 forHTTPHeaderField：@Content-type]; 
 
 NSString * xmlString = @< data>< item> Item 1< / item>< item> Item 2< / item>< / data>; 
 
 [请求setValue：[NSString stringWithFormat：@％d，
 [xmlString length]] 
 forHTTPHeaderField：@Content-length]; 
 
 [request setHTTPBody：[xmlString 
 dataUsingEncoding：NSUTF8StringEncoding]]; 
 
 [[NSURLConnection alloc] 
 initWithRequest：request 
 delegate：self]; 
  

I downloaded apple's demo for using HTTP POST and GET (Their sample app has a tabbar with different parts) and the code is so confusing!

Could anybody give me some sample code or a link to some tutorials about it? :)

Thanks!

This walkthrough by Matt Long is particularly good: http://www.cimgf.com/2010/02/12/accessing-the-cloud-from-cocoa-touch/

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] 
        initWithURL:[NSURL 
        URLWithString:@"http://www.cimgf.com/testpost.php"]];
 
[request setHTTPMethod:@"POST"];
[request setValue:@"text/xml" 
              forHTTPHeaderField:@"Content-type"];
 
NSString *xmlString = @"<data><item>Item 1</item><item>Item 2</item></data>";
 
[request setValue:[NSString stringWithFormat:@"%d",
        [xmlString length]] 
        forHTTPHeaderField:@"Content-length"];
 
[request setHTTPBody:[xmlString 
        dataUsingEncoding:NSUTF8StringEncoding]];
 
[[NSURLConnection alloc] 
        initWithRequest:request 
                   delegate:self];
