I am working on application which require a video upload functionality. I am using NSURLRequest for this and its working fine for video which is less then 1 minute in length, but cause problem when video is large. Do any one have any idea about that???
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setCachePolicy:NSURLRequestUseProtocolCachePolicy];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"----F00";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField:#"Content-Type"];
fileData = [NSData dataWithContentsOfURL:[mediaDict objectForKey:UIImagePickerControllerMediaURL]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"data[file_name]\"; filename=\"%#\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat: #"Content-Type: %#\r\n\r\n",fileContentType] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:fileData];
[request setHTTPBody:body];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
if (theConnection) {
// Create the NSMutableData to hold the received data.
// receivedData is an instance variable declared elsewhere.
self.receivedData = [NSMutableData data];
} else {
// Inform the user that the connection failed.
UIAlertView *didFailWithErrorMessage = [[UIAlertView alloc] initWithTitle: #"NSURLConnection " message: #"didFailWithError" delegate: self cancelButtonTitle: #"Ok" otherButtonTitles: nil];
[didFailWithErrorMessage show];
[spinnerView removeFromSuperview];
}
I really appreciate your help friends.
Set the timeout interval and check whether its working or not

You can use the CoreGraphics' method UIImagePNGRepresentation(UIImage *image), which returns NSData and save it. and if you want to convert it into again UIImage create it using [UIimage imageWithData:(NSData *data)] method. Some Questions related to this post image to server in iphone and
How to convert image into binary format in iOS? as giving the same answer 3 time.
- (void)sendImageToServer {
UIImage *yourImage= [UIImage imageNamed:#"image.png"];
NSData *imageData = UIImagePNGRepresentation(yourImage);
NSString *postLength = [NSString stringWithFormat:#"%d", [imageData length]];
// Init the URLRequest
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"POST"];

Use this code to upload any image to the server. This works for me. :)
UIImage *yourImage= [UIImage imageNamed:#"image.png"];
NSData *imageData = UIImagePNGRepresentation(yourImage);
NSString *postLength = [NSString stringWithFormat:#"%d", [imageData length]];
// Init the URLRequest
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:imageData];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection) {
// response data of the request
}
Try this

for (NSString *param in _params) {
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"%#\r\n", [_params objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];
}
// add image data
NSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0);
if (imageData) {
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]];

// set the content-length
NSString *postLength = [NSString stringWithFormat:#"%d", [body length]];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
// set URL
[request setURL:requestURL];
Note
"BoundaryConstant" is basically the variable "boundary" which is essentially a random (NSString *), "FileParamConstant" is basically your "filename.jpg"
You can also do by importing ASIFormDataRequest calss,Here is the link which tells Why to use this,after downloading classes just do like this,

I am new to iPhone and using XML in my application where i need to send one image to the server's one specific folder. For the same i am using the code :

NSString *urlString = [NSString stringWithFormat:#"http://111.111.11.1/webservices.asmx/PutImage"];

To upload data from your iPhone to your server:
- (void)sendImage {
NSData *postData = [nsdata from your original image];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
// Init and set fields of the URLRequest
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"POST"];
[request setURL:[NSURL URLWithString:[NSString stringWithString:#"http://yoururl.domain"]]];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection) {
// Return data of the request
NSData *receivedData = [[NSMutableData data] retain];
}
[request release];
}
I've an issue with the post of an UIImage on a PHP server, when I post it, the image received is empty.

// setting up the request object now
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
/*

Thanks for your help !
I suggest the use of ASIHTTPRequest for this kind of requests. You can do this much more easily with it. Here is an example to how send an image using ASIHTTPRequest:
// Initilize Queue
networkQueue = [[ASINetworkQueue alloc] init];
[networkQueue setUploadProgressDelegate:statusProgressView];
[networkQueue setRequestDidFinishSelector:#selector(imageRequestDidFinish:)];
[networkQueue setQueueDidFinishSelector:#selector(imageQueueDidFinish:)];
[networkQueue setRequestDidFailSelector:#selector(requestDidFail:)];
[networkQueue setShowAccurateProgress:true];
[networkQueue setDelegate:self];
NSData *imageData = UIImageJPEGRepresentation(yourImage, compression);
url = [NSURL URLWithString:#"http://myserver/upload.php"];
ASIFormDataRequest *request = [[[ASIFormDataRequest alloc] initWithURL:url] autorelease];
[request setPostValue:#"myImageName" forKey:#"name"];
[request addData:imageData withFileName:#"someFileName.jpeg" andContentType:#"image/jpeg" forKey:#"uploadedImage"];
[networkQueue addOperation:request];
[networkQueue go];
Hope it helps
I am currently uploading images to my server via HTTP POST. Everything works fine using the code below.
NSString *UDID = md5([UIDevice currentDevice].uniqueIdentifier);
NSString *filename = [NSString stringWithFormat:#"%#-%#", UDID, [NSDate date]];
NSString *urlString = #"http://taptation.com/stationary_data/index.php";
request= [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"userfile\"; filename=\"%#.jpg\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:imageData]];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(returnString);
However, when I try to convert this to work with Image Shacks XML API, it doesn't return anything. The directions from ImageShack are below.
Send the following variables via POST to imageshack. us /index.php
fileupload; (the image)
xml = "yes"; (specifies the return of XML)
cookie; (registration code, optional)
Does anyone know where I should go from here?
You might want to consider using ASIHTTPRequest, as it will build a form data post body for you with a lot less hassle, and can stream the request body from disk, so you'll save memory when uploading large images.
A quick google found this, which seems to suggest you should be posting to /upload_api.php rather than /index.php.
Something like this would probably be a good start:
ASIFormDataRequest *request = [[[ASIFormDataRequest alloc] initWithUrl:[NSURL URLWithString:#"http://www.imageshack.us/upload_api.php"]] autorelease];
[request setFile:#"/path/to/file" forKey:#"fileupload"];
[request setPostValue:#"yes" forKey:#"xml"];
[request setPostValue:#"blahblah" forKey:#"cookie"];
//It looks as though you probably need these too
[request setPostValue:#"me#somewhere.com" forKey:#"email"];
[request setPostValue:#"blah" forKey:#"key"];
[request start];
if ([request error]) {
NSLog(#"%#",[request error]);
} else {
NSLog([request responseString]); // The xml that got sent back
}
Warning: untested!
I've used a synchronous request because you did, but you almost certainly should be using an asynchronous request instead (a queue with ASIHTTPRequest).
Took me a while, but you need to use ASIHTTPREQUEST!
