HarmonyOS 鸿蒙Next 请问 OHOS::Rosen::RSAnimation::SetFinishCallback 这个方法具体是在什么时机会被调用？

经常会有c++崩溃指向这个地方。挠破头了都想不到是什么原因。求教

OHOS::Rosen::RSAnimation::SetFinishCallback 方法在鸿蒙操作系统（HarmonyOS）的动画框架中用于设置一个回调，该回调会在动画完成其执行周期时被调用。具体来说，这个回调函数的触发时机通常是在以下情况之一：

  1. 动画自然结束：当动画按照设定的时长和效果正常播放完毕时，SetFinishCallback 设置的回调函数会被触发。

  2. 动画被取消：如果动画在执行过程中被显式取消（例如通过调用某个取消动画的方法），并且系统支持在取消时触发完成回调，那么该回调也会被调用。不过，这一点可能依赖于具体的动画实现和鸿蒙系统的版本。

  3. 动画循环结束：对于设置为循环播放的动画，如果动画完成了设定的循环次数，且系统设计为在循环结束时触发完成回调，那么此时也会调用该回调。但通常，循环动画的完成回调逻辑可能需要开发者自行处理，以确保在最后一次循环结束时触发。

需要注意的是，具体行为可能因鸿蒙系统的不同版本和动画的具体实现而有所不同。如果问题依旧没法解决请联系官网客服，官网地址是：https://www.itying.com/category-93-b0.html
