当UIScrollView子视图与UITapGestureRecognizer一起使用时，它会释放(删除)内存

Question

这个例子非常简单，一堆UIImageView被作为子视图添加到一个UIScrollView中

for(NSDictionary *dict in info) {
    UIImageView *imageview = [[UIImageView alloc] initWithImage:image];
    imageview.frame = CGRectMake(x, 0, 91, 91);

    [self.scrollView addSubview:imageview];
        x+=95;
        [self.scrollView setContentSize:CGSizeMake(x, 91.0)];
        //define gestures
        //single tap for wide display
        UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(wideDisplay:)];
        imageview.userInteractionEnabled = YES;
        [imageview addGestureRecognizer:singleTap];
}

在UIImageView上点击一下后，它会被发送到wideDisplay:方法，以获得广泛的显示：

-(void)wideDisplay:(UITapGestureRecognizer*)gesture{

    UAModalPanel *wideScreen = [[UAModalPanel alloc] initWithFrame:self.view.bounds];
    wideScreen.padding = UIEdgeInsetsMake(20.0, 20.0, 20.0, 20.0);

    self.imageView = [[UIImageView alloc]init];
    self.imageView = (UIImageView*)gesture.view;
    self.imageView.frame = CGRectMake(20, 20, 790, 500);

    [wideScreen.contentView addSubview:self.imageView];
    [self.view addSubview:wideScreen];    

}

将imageView添加到模式视图后，此UIImageView将从滚动视图子视图中删除。imageView是一个强大的属性，但尽管如此，在添加到自定义模式视图后，它似乎正在失去引用，如何防止在选择它后将其从滚动视图中删除？

您不是在每次调用-wideDisplay:时都要处理和创建self.imageView吗
