Télécharger le formulaire avec l'image et nsstrings au fichier PHP

Question

Je suis en train d'envoyer des données de formulaire qui a une image et 2 nsstrings à un fichier php et je veux envoyer uiimage .image avec le nom de "document" et un nsstring avec le nom de "nom" et un autre nsstring avec le nom de "userid".

Voici mon code jusqu'à présent.

NSData *imageData = UIImageJPEGRepresentation(Myimage.image, 1.0); 
       if (imageData != nil) 
       { 
        NSString *filename = [NSString stringWithFormat:@"%@",name];  //set name here 
        NSLog(@"%@", filename); 
        NSString *urlString = @"http://URL/upload.php"; 
        NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
        [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 *body = [NSMutableData data]; 
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
        [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"filenames\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
        [body appendData:[filename dataUsingEncoding:NSUTF8StringEncoding]]; 
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
        [body appendData:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\".jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
        [body appendData:[@"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]; 
        NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
        NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 
        NSLog(@"%@", returnString); 
        NSLog(@"finish"); 
}

NSData *dataImage = UIImagePNGRepresentation(yourImage); 

NSString *imageBase64 = [dataImage base64forData]; 

- (NSString*)base64forData 
{ 
    const uint8_t* input = (const uint8_t*)[self bytes]; 
    NSInteger Datalength = [self length]; 

    static char table[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz/="; 

    NSMutableData* data = [NSMutableData dataWithLength:((Datalength + 2)/3) * 4]; 
    uint8_t* output = (uint8_t*)data.mutableBytes; 

    NSInteger i; 
    for (i=0; i < Datalength; i += 3) { 
     NSInteger value = 0; 
     NSInteger j; 
     for (j = i; j < (i + 3); j++) { 
      value <<= 8; 

      if (j < Datalength) { 
       value |= (0xFF & input[j]); 
      } 
     } 

     NSInteger theIndex = (i/3) * 4; 
     output[theIndex + 0] =     table[(value >> 18) & 0x3F]; 
     output[theIndex + 1] =     table[(value >> 12) & 0x3F]; 
     output[theIndex + 2] = (i + 1) < Datalength ? table[(value >> 6) & 0x3F] : '='; 
     output[theIndex + 3] = (i + 2) < Datalength ? table[(value >> 0) & 0x3F] : '='; 
    } 

    return [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
