zmage是否在被卸载时清除了异步任务
移动端中 使用Zmage.browsing方式和Zmage组件,图片回到原来位置时,两种使用方式的还原动画不一致,该还原动画效果可以设置参数进行控制么?
我也遇到了同样的问题 @Caldis

@Alisa0026 看上去是这个样子的,我使用了Zmage.browsing方法而不是组件的形式会避免开这个问题,不过还存在移动端无法缩放的问题,所以我改用了这个 react-photo-view 组件 看上去更精致一些。

谢谢反馈, 经检查貌似是严格模式的 <React.StrictMode/> 导致的, 而且会导致组件重复渲染
browsing 这块的 unInit 处理是一个反模式, 后续会优化
