Téléchargement d'une image depuis iOS vers PHP

Question

J'ai travaillé sur le téléchargement d'une image UII vers un serveur Web. Le problème est que l'image n'apparaît jamais sur le serveur. Un POST normal à partir d'un fichier HTML fonctionne. Je pense que c'est un problème dans mon code objectif-c.

Voici mon code objectif-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]); 

Voici mon code 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"; 
} 
?>

Maintenant, je l'ai résolu par moi-même =)

J'ai oublié les antislashs dans le corps.

Voici le corps droit:

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];
