上传图像服务器在iPhone应用程序

我要上传图片中的iPhone应用程序，以断绝我使用下面的代码PHP上传图像服务器在iPhone应用程序

但使用此代码我收到错误，当我运行本地主机/ upload.php的页面上显示;

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

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) { 
    echo "OK"; 
else { 
echo "ERROR"; 
} 

    ?>

下面是iPhone的Xcode代码

- (BOOL)uploadImage:(NSData *)imageData filename:(NSString *)filename{ 


     NSString *urlString = @"http://localhost/upload.php"; 

     NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; 
    [request setURL:[NSURL URLWithString:urlString]]; 
     [request setHTTPMethod:@"POST"]; 

     NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; 
     NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
     [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

     NSMutableData *body = [NSMutableData data]; 
     [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:[NSString stringWithFormat:@"Content- Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n",filename]] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[NSData dataWithData:imageData]]; 
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [request setHTTPBody:body]; 

    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
    NSString *returnString = [[[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding] autorelease]; 

    return ([returnString isEqualToString:@"OK"]); 
     }

调用方法

 [self uploadImage:UIImageJPEGRepresentation(imageView.image, 1.0) filename:@"pig.jpg"];

我回答这里看到这个 http://stackoverflow.com/questions/8474063/how-to-upload-image-dynamically-on-server/15153502#15153502 – vinothsivanandam 2013-03-01 08:42:18

，如果你认为在PHP代码错误，那么第一次尝试这种print_r($_FILES);，看看你在$_FILES['userfile']得到

[正文appendData：[[的NSString stringWithString：[的NSString stringWithFormat：@“内容处置：形状数据;命名= \ “userfile的\”;文件名= \ “％@ \” \ r \ n “个，文件名]] dataUsingEncoding：NSUTF8StringEncoding]]; 是这条线是正确的，其中文件名 – user1263350 2012-03-14 05:58:58

尝试此[身体appendData：[[的NSString stringWithFormat：@” 内容处置：form-data;命名= \ “userfile的\”;文件名= \ “％@ \” \ r \ n”，文件名] dataUsingEncoding：NSUTF8StringEncoding]];和文件名是文件（即扩展名） – hchouhan02 2012-03-14 06:31:01

的完整名称，为什么你使用的NSString stringWithString：和NSData的dataWithData：方法 – hchouhan02 2012-03-14 06:31:41

试试这个，也没有你的PHP通过查询

    NSString *urlString = @"http://localhost/upload.php"; 

        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString] cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:60]; 
        [request setHTTPMethod:@"POST"]; 

        NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; 
        NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
        [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

        NSMutableData *body = [NSMutableData data]; 
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
        [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]]; 
        [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
        [body appendData:imageData]; 
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
        [request setHTTPBody:body]; 

        NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
        NSString *returnString = [[[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding] autorelease];
