这里有一个类似的问题： File Upload to HTTP server in iphone programming

代码：

NSString *urlString = @"http://yourserver.com/upload.php"; 
NSString *filename = @"filename"; 
request= [[[NSMutableURLRequest alloc] init] autorelease]; 
[request setURL:[NSURL URLWithString:urlString]]; 
[request setHTTPMethod:@"POST"]; 
NSString *boundary = @"---------------------------14737809831466499882746641449"; 
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
[request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 
NSMutableData *postbody = [NSMutableData data]; 
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.jpg\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]]; 
[postbody appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[postbody appendData:[NSData dataWithData:YOUR_NSDATA_HERE]]; 
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[request setHTTPBody:postbody]; 

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