Local or Cloud? Which is the better choice?
中文位于文章的下半部分
Weekly Comment
"Yuque(语雀)" is a well-known cloud note service provider in China, positioned as a knowledge base tool, highly favored by IT companies and developers. However, last week Yuque encountered a severe online outage that lasted for a whole 7 hours. Coupled with the founder's departure a few months ago, various speculations circulated on the internet. Eventually, the problem was resolved, and in order to appease public opinion, Yuque offered six months of free membership as compensation to its users.
This incident has raised concerns about cloud services and reignited interest in local storage, which involves saving data and content on local devices rather than solely relying on cloud services.
Recently, my Twitter timeline has been filled with discussions about Local First. Many friends have started transferring their content stored in the cloud to local storage, and some have even completely abandoned cloud services in favor of purely localized applications.
However, cloud services do have their advantages. They provide convenient collaboration and sharing features, enabling team members to access and edit documents in real time. Additionally, cloud services usually have high availability and backup mechanisms to ensure data persistence and reliability.
Regardless of the chosen approach, it is important for personal documents to have multiple backup methods to ensure security. At the same time, when selecting a cloud document service provider, the ease of exporting documents and compatibility with other platforms are also important considerations.
Through this Yuque outage incident, we can see that the Local First concept is gradually gaining popularity and acceptance among users. This also serves as a reminder for cloud service providers to pay more attention to user needs and provide more stable and reliable services to meet different users' requirements for data storage and management.

Mastering TipKit: Advanced
The essence of TipKit lies not in its external visual effects, but in its internal logical expression. It helps developers describe the rules for generating tips in a declarative manner, while the specific implementation of the tips can be completely customized. We can think of TipKit as a rule engine that determines when to display tips, and how to visualize these rules is up to the developers themselves. In this article, we will discuss some advanced topics related to TipKit, such as how to fully customize the tip view (without using TipView and popoverTip), how to use TipKit in UIKit, and how TipKit can share data between different applications. Finally, we will attempt to answer some questions related to TipKit.
If you are not familiar with the TipKit framework, please read the article Mastering TipKit: Basics.

How to Use PHPicker to Access Resources on iOS System without Authorization
狐友靳凯@sohu
PHPicker is a new component introduced in iOS 14. It allows access to all resources in the photo library without requiring user authorization. This article provides a detailed guide on how to correctly use PHPicker to access selected photo resources from users. The key point is that there is no need to obtain authorization in advance, instead, multimedia resources are handled through NSItemProvider. This approach aligns with the system's design intention and improves the user experience.
肘子的话
“语雀”是中国知名的云端笔记服务商，定位为知识库工具，备受IT企业和开发者的喜爱。然而，上周语雀遭遇严重的线上故障，持续了整整 7 个小时。再加上几个月前创始人离职的事件，网络上一度流传各种猜测。最终，问题得到解决，为了平息舆论，语雀向用户提供了六个月的免费会员资格作为补偿。
这次故障事件引发了人们对云端服务的担忧，并重新激起了对本地化存储的兴趣，即将数据和内容保存在本地设备上，而不仅仅依赖于云端服务。
这几天，我的 Twitter 时间线上出现了大量有关 Local First 的讨论。许多朋友开始将保存在云端的内容转存至本地，有些甚至完全放弃了云端服务，转而使用纯本地化的应用。
然而，云端服务并非完全没有优势。云端服务能提供便捷的协作和共享功能，使团队成员能够实时访问和编辑文档。此外，云端服务通常具备高可用性和备份机制，确保数据的持久性和可靠性。
无论采用哪种方式，个人文档都应该有多种备份方式来确保安全。同时，在选择云文档服务商时，文档易导出性和与其他平台的互通性也是重要的考量因素。
通过这次语雀故障事件，我们可以看到 Local First 理念在用户中逐渐普及和接受。这也提醒云端服务提供商们要更加关注用户需求，提供更加稳定可靠的服务，以满足不同用户对数据存储和管理的需求。
