Drag elements UIImageView. Using a NSMutableArray
===

**.m**

    self.elements=[myElements getElements];
    
    imagesElements = [[NSMutableArray alloc]init];
    for(ElemetsList *item in self.elements)
    {
            UIImageView *oneelement = [[UIImageView alloc] initWithImage:[UIImage imageNamed:item.imgElement]];
            oneelement.frame = CGRectMake(item.positionX, item.positionY, item.width, item.height);
            oneelement.userInteractionEnabled=YES;
            [imagesElements addObject:oneelement];
    }
    
    for(UIImageView *img in imagesElements) 
        [self.view addSubview:img];
    
Then I try to interact with the elements:

    -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
    {
        UITouch *touch = [[event allTouches] anyObject];
    
        for(UIImageView *img in imagesElements) 
        {  
            if([self view] == img)
            {
                CGPoint location = [touch locationInView:self.view];
                img.center=location;
            }
        }
    }

But "if ([self view] == img)" is always "NO". Therefore, the elements do not drag.
How to drag and drop items if they are in the array?
