複数のイメージファイルをサーバーに送信する方法

私はこのコードを使用しており、単一のイメージのみをサーバーに送信できます。 I 複数の選択されたイメージファイルをサーバーに送信します。このコードを見て間違いの可能性がありますので、この問題を解決するためにを手伝ってください。あなたの時間をありがとう。複数のイメージファイルをサーバーに送信する方法

再チェックした後、私は私が間違ったイメージ配列を渡したがあったことです。今これは同じ変更した後に動作しています。あなたの時間と配慮に感謝します。

NSLog(@"ARRAYCOUNT: %lu", (unsigned long)imgArray.count); 
for (int y = 0; y < [arrImage count]; y++) 
{ 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

NSString * image_name =[NSString stringWithFormat:@"%@%d",@"image",y]; 
NSLog(@"IMAGE NAME:%@", image_name); 

UIImage* imageFile = [arrImage objectAtIndex:y]; 

CGSize newSize = CGSizeMake(500.0f, 500.0f); 
UIGraphicsBeginImageContext(newSize); 
[imageFile drawInRect:CGRectMake(0,0,newSize.width,newSize.height)]; 
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext(); 
UIGraphicsEndImageContext(); 

NSData *dataImg = [NSData 
dataWithData:UIImagePNGRepresentation(newImage)]; 

//NSData *dataImg = [NSData dataWithData:UIImagePNGRepresentation([imgArray objectAtIndex:y])]; 

NSLog(@"added %i", y+1); 
NSLog(@"Images, send to server:%@", dataImg); 

[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"site_image\"; filename=\"%@\"\r\n",image_name] dataUsingEncoding:NSUTF8StringEncoding]];
