How to send an image using a POST request in iOS

Question

I need to send image to my server using post request. I have written the required PHP code for it. But how I have to send it from my device? I have seen ASIHTTPRequest framework, but it is out of date, and AFNetworking is complicating things. If I could I would want to send an image through GET request, but i just don't know how.

I created a subclass which allows you to create easy asynchronous POST requests and can be found here: https://github.com/MaxKDevelopment/MKNetwork.

To use it to upload an image, all you need to do is add the image data as a parameter to the request:

[MKNetwork sendAsynchronousRequest:[NSURL URLWithString:@"url to upload to"] params:[NSDictionary dictionaryWithObject:UIImagePNGRepresentation(imagedata) forKey:@"image"] decodeResponse:YES callback:^(id response, NSError *error) {

    [someObject doSomethingWithResponse:response];

}];

Or, you could look into ASIHTTPRequest (ASIFormDataRequest): http://allseeing-i.com/ASIHTTPRequest/

Then initialise a ASIFormDataRequest variable with a POST value set as the UIImage.

NSURL *url = [NSURL URLWithString: @"url to upload to];
ASIFormDataRequest *request = [ASIHTTPRequest requestWithURL:url];
[request addPostValue:UIImagePNGRepresentation(imageToUpload) forKey:@"image"];
[request setCompletionBlock:^{NSLog(@"completed");}];
[request setFailedBlock:^{NSLog(@"failed");}];
[request startAsynchronous];
