从iphone上传图片到服务器文件夹

问题描述：

我发现从在线上的图片从iPhone上传图片到服务器文件夹，其显示使用服务器端脚本例如。使用PHP在服务器端从iphone上传图片到服务器文件夹

<?php 
$uploaddir = 'uploads/'; 
$file = basename($_FILES['userfile']['name']); 
$uploadfile = $uploaddir . $file; 

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) { 
     echo "Uploaded!"; 
}else{ 
    echo "Not Uploaded!"; 
} 
/>

是任何possibilites直接上传图片到服务器上的文件夹没有上面的代码，

让的说我要上传到http://111.22.333.44/mysite/pics/瓦特/ O任何服务器端脚本，如果如何可以做到这一点

感谢

// now lets make the connection to the web 
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 

NSLog(returnString);

这个代码将会对你有所帮助....

我不得不删除与应用行/ octet-让它与attachment_fu一起工作。任何想法为什么？ – 2011-04-23 14:09:05

这是伟大的代码。第一次为我工作。谢谢parvind :) – Prerna 2011-07-28 11:50:11

请注意上传文件的大小。你正在创建内存中整个文件内容的请求，然后发送它......如果文件太大（或者你并发地上传了很多文件），你可能会遇到内存消耗问题 – JakubKnejzlik 2014-07-23 03:08:40

如果你设置你的网站服务器允许PUT方法可以做到这一点。 99％的Web服务器只允许GET和POST方法。

从来没有这样做，我不能给你很多帮助。这里是一个网页，我从谷歌得到了谈论它：
