问题描述
我在图像上点击操作时遇到问题。我有一个简单的项目列表，每行有 4 个按钮。每行有 4 张图片，每张图片上都有一个 onTapGesture 操作链接。我第一次加载列表并且一切正常，但是当我尝试在列表中添加一个新项目（通过在导航栏上添加链接）时，会创建一个新行，但是如果我尝试点击，点击操作不起作用我添加的最后一行中的 4 张图像之一。例如，向上或向下箭头需要向上或向下移动一行。添加新行后，新行上的向上/向下箭头不起作用，但如果我点击最后一行 -1 向下箭头，两行开关和插入行上的图像点击操作开始起作用。
子类别列表来自另一个视图。

插入 2 行并重新加载视图后 [1]： https://i.stack.imgur.com/DL0No.png
点击向上足球箭头 [2] 后： https://i.stack.imgur.com/pTmXH.png
添加了高尔夫，但如果我尝试点击向上箭头，它不会向上移动 [3]： https://i.stack.imgur.com/s101V.png
有什么想法吗？谢谢大家
