的touchesBegan / touchesMoved

Question

我正在尝试一个只有图片的应用。然后，当用户触摸图像时，会创建一个副本，然后将图像移动到另一个位置并将其放在那里。

这是我创建的代码：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

UITouch *myTouch = [[event allTouches] anyObject];

CGPoint touch_point = [myTouch locationInView:view1];

    if ([view1 pointInside:touch_point withEvent:event]) {
        UIImageView *view= [UIImageView alloc];
        [self.view addSubview:view];
        [view release];
        view.userInteractionEnabled=YES;
        view.frame = CGRectMake(0, 0, 100.0, 100.0);
        view.center = [myTouch locationInView:self.view];
    }       

}

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {

    UITouch *myTouch = [[event allTouches] anyObject];

    CGPoint touch_point = [myTouch locationInView:view1];

    if ([view1 pointInside:touch_point withEvent:event]) {
        view.image=view1.image;
    }

}

我的问题是我无法访问touchesBegan中创建的*视图，并在touchesMoved中使用它。是否有人知道公开这个图像视图？
