在上面的代码中，您只是选择视频文件，没有上传视频或其中使用的任何flickr API的代码。因此，请尝试以这种方式上传视频： -

NSString *uploadSig = [[NSString stringWithFormat:@"%@api_key%@auth_token%@", secret, api_key, auth_token] MD5]; 

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; 
NSString *url = [NSString stringWithFormat:@"http://api.flickr.com/services/upload/"]; 
[request setURL:[NSURL URLWithString:url]]; 
[request setHTTPMethod:@"POST"]; 


NSString *boundary = [NSString stringWithString:@"---------------------------7d44e178b0434"]; 

[request addValue:[NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary] forHTTPHeaderField: @"Content-Type"]; 

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

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

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

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

[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"photo\"; filename=\"photo.jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

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