几个在 SwiftUI 中使用惰性容器的技巧和注意事项

在 SwiftUI 的框架中，惰性布局容器，如 List 和 LazyVStack，提供了一种高效展示大型数据集的方法。这些容器的设计精妙，它们仅在必要时才动态地构建和加载视图，从而显著优化了应用的性能和内存使用效率。本文将探讨一些实用技巧和重要注意事项，旨在赋予开发者利用 SwiftUI 惰性容器时增强应用响应性和资源管理的能力。

Tips and Considerations for Using Lazy Containers in SwiftUI

In the SwiftUI framework, lazy layout containers such as List and LazyVStack provide a method for efficiently displaying large datasets. These containers are ingeniously designed to dynamically build and load views only when necessary, thereby significantly optimizing the app's performance and memory efficiency. This article will explore some practical tips and important considerations aimed at enhancing developers' ability to leverage SwiftUI's lazy containers for improved app responsiveness and resource management.

使用RandomAccessCollection来触发加载更多确实是一个新的思路，虽然比直接在最后一个cell上加block要麻烦一点，但是处理的空间更灵活，可以实现还未滚动到最后一个cell之前就提前加载的逻辑。稍微封装一下就能很好用。
