Question

I am trying to upload a image which i am clicking with the help of the camera. I am trying the following code to upload the image to the remote server.

-(void)searchAction:(UIImage*)theImage
{
    UIDevice *dev = [UIDevice currentDevice];
    NSString *uniqueId = dev.uniqueIdentifier;

    NSData * imageData = UIImagePNGRepresentation(theImage);

    NSString *postLength = [NSString stringWithFormat:@"%d",[imageData length]];

    NSString *urlString = [@"http://www.amolconsultants.com/im.jsp?" stringByAppendingString:@"imagedata=iPhoneV0&mcid="];
    urlString = [urlString stringByAppendingString:uniqueId];
    urlString = [urlString stringByAppendingString:@"&lang=en_US.UTF-8"];

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody:imageData];

    NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self];
    if (conn == nil) 
    {
        NSLog(@"Failed to create the connection");
    }
}

But nothing is getting posted. Nothing comes in the console window also. I am calling this method in the action sheet. When the user clicks on the 1st button of the action sheet this method is called to post the image.

Can anyone help me with this…

Any code will be very helpful…

Thanx in advance…

You can use the libraries from a third party called asi-http-request. It simplyfies for you most of the hard works. In your case, you just do as the following:

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request appendPostData:imageData];
[request setRequestMethod:@"PUT"];
