在我的应用程序中，我正在 iPad 中录制视频，我想将其上传到我的服务器。请让我知道如何实现这一目标。

创建包含文件对象的请求字典，稍后 postWith: 函数将处理您的视频绑定任务

NSDictionary *requestDict = [NSDictionary dictionaryWithObjectsAndKeys:@"FirstObjectValue",@"FirstKey",
                             @"Second Object",@"Second Key",
                             @"myFileParameterToReadOnServerSide",@"file", nil]; // This line indicate ,POST data has file to attach
[self postWith:requestDict];

如果要发送视频，以下函数将从要发布的对象字典中读取所有参数，然后在字典中添加“文件”键，以标识要随请求发送的文件

- (void)postWith:(NSDictionary *)post_vars
{
#warning Add your Webservice URL here        
    NSString *urlString = [NSString stringWithFormat:@"YourHostString"];

    NSURL *url = [NSURL URLWithString:urlString];
    NSString *boundary = @"----1010101010";

    //  define content type and add Body Boundry
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    [request setHTTPMethod:@"POST"];
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"];

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

    NSEnumerator *enumerator = [post_vars keyEnumerator];
    NSString *key;
    NSString *value;
    NSString *content_disposition;

    while ((key = (NSString *)[enumerator nextObject])) {

        if ([key isEqualToString:@"file"]) {

            value = (NSString *)[post_vars objectForKey:key];
            //  ***     Write Your Image Name Here  ***
            // Covnert Video to Data and bind to your post request
#warning Add your Video From Path 
            NSString *videoFilePath = [[NSBundle mainBundle] pathForResource:@"MyVideo" ofType:@"mp4"];
            NSData *postData = [NSData dataWithContentsOfFile:videoFilePath];

            [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\";\r\nfilename=\"testUploadFile.mp4\"\r\n\r\n",value] dataUsingEncoding:NSUTF8StringEncoding]];
            [body appendData:postData];
        } else {
            value = (NSString *)[post_vars objectForKey:key];

            content_disposition = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", key];
            [body appendData:[content_disposition dataUsingEncoding:NSUTF8StringEncoding]];
            [body appendData:[value dataUsingEncoding:NSUTF8StringEncoding]];

        }

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

    }

    //Close the request body with Boundry
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    [request setHTTPBody:body];
    [request addValue:[NSString stringWithFormat:@"%d", body.length] forHTTPHeaderField: @"Content-Length"];

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