通过http post使用块上传大型视频

Question

我想将大型视频从iPhone上传到网络服务器.我试过下面的代码.它适用于小文件,但当我尝试上传大文件时,它会崩溃.

码:

NSMutableURLRequest *request = [NSMutableURLRequest
                                requestWithURL:[NSURL URLWithString:@"https://XXXXXXXXXXXXXXXX/submit.php"]];

NSData *webData = [NSData dataWithContentsOfURL:movieUrl];
NSString *postLength = [NSString stringWithFormat:@"%d", [webData length]];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];

---- added some HTTP headers here ----

[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];

NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[NSData dataWithData:webData]];
[request setHTTPBody:postbody];

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

经过研究我得到了一个想法,如果我在大块数据中发送大文件,这将是可能的.solution1,solution2.

我还经历了Stream Programming apple doc. 但不知道在哪里定义服务器NSURL.将数据写入输出流后如何发送到服务器.

如果有人能指出我的任何工作代码,那么我将能够更好地理解它.

怎么做？有什么想法吗？
