//假设自己的视频文件URL为变量myVideoURL

//1.获取视频文件名字

NSString *videoName = [myVideoURL lastPathComponent];

//2.将视频URL转位Data

NSData *dataFromURL = [[NSData alloc] initWithContentsOfURL:myVideoURL];

//3.将上传地址转为NSString

NSString *url [NSStringstringWithFormat:@"http://api.myVideo"];

//4.定义字典，将需要给服务器传参，写进字典

NSMutableDictionary *parameters = [[NSMutableDictionary alloc]init];

//5.下面是AFNetWorking的接口函数

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html",@"text/json",@"application/json",@"text/javascript", nil];

[manager POST:url parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData)

{

//以下三个参数依次为：视频，视频名字，视频格式

[formData appendPartWithFileData:dataFromURL name:@"file" fileName:videoName mimeType:@"video/quicktime"];

} success:^(AFHTTPRequestOperation *operation, id responseObject)

{

NSLog(@"成功，结果是：%@",responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error)

{

NSLog(@"失败，原因是：%@",error);

} ];

//如果需要给视频上传增加进度条，请使用下面的方法。

//加载进度条

UIProgressView *progressView = [[UIProgressView alloc]initWithProgressViewStyle:UIProgressViewStyleDefault];

progressView.frame = CGRectMake(0, 52, screen_width, 10);

//设置进度条背景颜色

progressView.trackTintColor = [UIColor whiteColor];

//设置进度条进度颜色

progressView.progressTintColor = [UIColor redColor];

//设置进度默认值

progressView.progress = 0.0;

[self.view addSubview:progressView];
