Uploading NSData image via POST in iOS - ios

Question

i have a form that contains some person information and an image. i tried to save information in post using this function and it work well :
- (void)Inscription:(NSArray *)value completion:(void (^)( NSString * retour))block{
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
NSArray *Param_header = #[#"username", #"password", #"email",#"first_name", #"last_name",#"image"];
// NSArray *Param_value = #[#"ali", #"aliiiiiiii", #"ali.ali#gmail.com",#"ali",#"zzzzz"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString: [NSString stringWithFormat:#"http:// /Messenger/services/messenger_register"]]];
NSString *aa=[self buildParameterWithPostType:#"User" andParameterHeaders:Param_header ansParameterValues:value];
[request setHTTPBody:[aa dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPMethod:#"POST"];
[NSURLConnection sendAsynchronousRequest: request
queue: queue
completionHandler: ^(NSURLResponse *response, NSData *data, NSError *error) {
if (error || !data) {
// Handle the error
NSLog(#"Server Error : %#", error);
} else {
NSError *error = Nil;
id jsonObjects = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
block([NSString stringWithFormat:#"%#", [jsonObjects objectForKey:#"message"]]);
}
}
];
}
No, i want to send the photo taked, i convert it to NSData first :
[picker dismissViewControllerAnimated:YES completion:nil];
UIImage *imag= [info objectForKey:#"UIImagePickerControllerOriginalImage"];
imag = [imag scaleAndRotateImage:imag];
CGFloat compression = 0.9f;
CGFloat maxCompression = 0.1f;
int maxFileSize = 25*1024;//was 250x1024
NSData *imageData = UIImageJPEGRepresentation(imag, compression);
while ([imageData length] > maxFileSize && compression > maxCompression)
{
compression -= 0.1;
imageData = UIImageJPEGRepresentation(imag, compression);
}
NSData _D_ImageData = imageData;
And i tried to do this to send it to server but image c'ant be uploaded:
[web Inscription:Param_value completion:^(NSString *retour) {
CustomPrpgress.hidden=true;
NSLog(#" eee %# ",retour);
UIAlertView *alert=[[UIAlertView alloc] initWithTitle:retour message:#"" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
}];
