How to Upload Large Video Files in Objective-C

// Get video
NSSstring*dir = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents";
NSSstring* path = [dir stringByAppendingPathComponent:@"test.mov";
NSData* videoData=[NSDataDataWithContentsOfURL:[NSURL fileURLWithPath:path]];

// Upload Video
AFHTTPRequestOperationManager*manager = AFHTTPRequestOperationManager manager;
manager.responseSerializer = AFHTTPResponseSerializer;
[manager.requestSerializer setTimeoutInterval:50];

[manager POST:@"(omitted)/deployMovieTest.php" parameters:nil constructionBodyWithBlock:^(id<AFMultipartFormData>formData){
    [formData appendPartWithFileData:videoDataname:@"movie"fileName:@"test.mov"mimeType:@"video/quicktime";
} success:^(AFHTTPRequestOperation* operation, id responseObject) {
    NSLog(@"Success: Show JSON %@", responseObject);
    NSSstring* responseStr = [[NSSstring alloc] initWithData: responseObject encoding:NSUTF8 StringEncoding];
    NSLog(@"Success: Display characters %@",responseStr);
} failure:^(AFHTTPRequestOperation*operation, NSError*error){
    NSLog(@"Failure:%@", error);
}];

<?php

// Information received at POST is in $_FILES.
// Receive video at POST.
$image=file_get_contents($_FILES['movie']['tmp_name']);


// Created the destination URL to be moved.
$uploaddir='(omitted)/uploads/';
$uploadfile=$uploaddir.basename($_FILES['movie']['name']);

// Saved the file.
$message="";
if(move_uploaded_file($_FILES['movie']['tmp_name'], $uploadfile)){
    $message="OK!\n";
} else{
    $message="NO:)";
}

// output
header('Content-type:application/json');
echo json_encode($message);
