推荐答案

首先让我给您一些建议，就是从这样的设备上传文件

Let me give you some suggestion first just upload the file from device like this

1.

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{


NSString *mediaType = info[UIImagePickerControllerMediaType];

if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
 {
    // Media is an image
    picImage = [info objectForKey:UIImagePickerControllerOriginalImage];
    NSString  *imagePath = [NSHomeDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"Documents/image.jpg"]];

    filePath = imagePath;
    [UIImageJPEGRepresentation(picImage, 1.0) writeToFile:imagePath atomically:YES];
    arrayMute = (NSMutableArray*) [self sendData:filePath]  
 }
}

2现在只需通过ASIFormDataRequest将媒体上传到Web服务，然后它们将生成链接并提供给该链接.然后您可以通过xmpp将链接发送给其他用户.然后其他用户可以下载该媒体.

2 Now just upload the media to webservices via ASIFormDataRequest then they will generate the link give back to the link. then u can send that link to another user via xmpp. and then other user can download that media.

-(NSMutableArray*)sendData:(NSString*)multiMData
{
  ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://194.158.1.25/IphoneVideoService/webservice.asmx/GetData1"]];

[request addRequestHeader: @"Content-Type" value:
 @"application/x-www-form-urlencoded"];

[request setDelegate:self];

[request setDidFailSelector:@selector(uploadFailed:)];

[request setUploadProgressDelegate:progressToDownload];

[request setDidFinishSelector:@selector(uploadFinished:)];

[request setDidFinishSelector:@selector(requestFailed:)];
[request setDidFinishSelector:@selector(requestFinished:)];

[request setShouldContinueWhenAppEntersBackground:YES];

NSString *url = [[NSURL fileURLWithPath:multiMData] path];

    [request setFile:url withFileName:[NSString stringWithFormat:@"Hello.jpeg"] andContentType:@"image/jpeg" forKey:@"file"];

[request setTimeOutSeconds:50000];
[request setRequestMethod:@"POST"];

[request startSynchronous];


SBJSON *sbJason = [[SBJSON alloc] init];

NSMutableArray *getUploadArray = [sbJason objectWithString:responseForMedia];

return getUploadArray;


 }
