Cargando una imagen de iOS a PHP

Question

He estado trabajando para cargar un UIImage a un servidor web. El problema es que la imagen nunca aparece en el servidor. Un POST normal de un archivo HTML funciona. Creo que es un problema en mi código objetivo-c.

Aquí está mi código Objective-C:

NSData *imageData = UIImagePNGRepresentation(delegate.dataBean.image); 
NSString *urlString = [NSString stringWithFormat:@"%@test.php", delegate.dataBean.hosterURL]; 

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
[request setURL:[NSURL URLWithString:urlString]]; 
[request setHTTPMethod:@"POST"]; 

NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; 
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
[request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

NSMutableData *body = [NSMutableData data]; 
[body appendData:[[NSString stringWithFormat:@"rn--%@rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"test.png\"rn"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-streamrnrn"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[NSData dataWithData:imageData]]; 
[body appendData:[[NSString stringWithFormat:@"rn--%@--rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[request setHTTPBody:body]; 

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 

NSLog([NSString stringWithFormat:@"Image Return String: %@", returnString]); 

Aquí está mi código PHP:

<?php 
$uploaddir = 'uploads/'; 
$file = basename($_FILES['uploadedfile']['name']); 
$uploadfile = $uploaddir . $file; 

echo "file=".$file; //is empty, but shouldn't 

if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $uploadfile)) { 
    echo $file; 
} 
else { 
    echo "error"; 
} 
?>

Ahora he resuelto por mí mismo =)

me olvidaron las barras invertidas en el cuerpo.

Aquí está el cuerpo de la derecha:

NSMutableData *body = [NSMutableData data]; 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"test.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[NSData dataWithData:imageData]]; 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[request setHTTPBody:body];
