您必須設置HTTP標題還如下：

NSMutableURLRequest* post = [NSMutableURLRequest requestWithURL: [NSURL URLWithString: @"http://115.111.27.206:8081/vblo/upload.jsp"]]; 
[post setHTTPMethod: @"POST"]; 


NSString *boundary = [NSString stringWithString:@"---------------------------358734318367435438734347"]; 

NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 

[post addValue:contentType forHTTPHeaderField: @"Content-Type"]; 


NSMutableData *body = [NSMutableData data]; 

[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"videofile\"; filename=\"videofile.3gp\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 

[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 


[body appendData:[NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"video" ofType:@"3gp"]]]; 

[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 


[post setHTTPBody:body]; 

NSData *returnData = [NSURLConnection sendSynchronousRequest:post returningResponse:nil error:nil]; 

NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 

NSLog(returnString);

，或者如果你想異步請求，那麼你可以調用initWithRequest NSURLConnection的方法。

感謝您的回覆。我修改了上面的代碼，我收到警告和應用程序終止。我是初學iphone應用程序，所以我感到困惑。請幫助我。 – sny 2010-11-22 08:14:18

嗨，我沒有看到你之前加載的數據，你是加載字符串作爲數據，而不是視頻數據，我已經糾正了上述代碼，現在嘗試.. – Sanniv 2010-11-22 09:10:12

是的，現在我糾正了，但它給上傳video.is代碼足以使uplooding示例視頻。我想從服務器mesg應該像上傳成功，我不喜歡那樣。 – sny 2010-11-22 09:34:15
