Question 1

How to add pull-to-refresh to UITableView with MJRefresh?

Accepted Answer

Use the mj_header property with MJRefreshNormalHeader or MJRefreshGifHeader, as shown in the 'The drop-down refresh 01-Default' example. Simply set the refreshing block or target-action, and call beginRefreshing to trigger it immediately.

Question 2

MJRefresh vs UIRefreshControl: which is better?

Accepted Answer

MJRefresh offers more customization, GIF support, and footer/trailer refresh, while UIRefreshControl is Apple's built-in but basic solution. Choose MJRefresh for advanced features and multi-view support, but UIRefreshControl for simplicity and native integration in UIKit apps.

Question 3

How to customize MJRefresh header with GIF images?

Accepted Answer

Refer to 'The drop-down refresh 02-Animation image' example: create a MJRefreshGifHeader, set images for different states (idle, pulling, refreshing) using setImages:forState:, and assign it to the scroll view's mj_header property.

Question 4

Does MJRefresh work with SwiftUI?

Accepted Answer

No, MJRefresh is designed for UIKit and does not provide SwiftUI components. You would need to wrap it in a UIViewRepresentable for SwiftUI integration, which adds complexity and may not be seamless.

Question 5

How to implement internationalization in MJRefresh?

Accepted Answer

Use MJRefreshConfig.default.language to set the language, and ensure your DIY components override i18nDidChange, as described in the 'Dynamic i18n Switching' section. Built-in components automatically rerender with the new language.

Question 6

What are the system requirements for MJRefresh?

Accepted Answer

Requires iOS 9.0 or later and ARC, as noted in the 'Remind' section. It supports iPhone and iPad in any orientation, but not earlier iOS versions or non-ARC projects.

Question 7

How to install MJRefresh using Swift Package Manager?

Accepted Answer

SPM is supported from version 3.7.1, as indicated in the README. Add the GitHub repository URL as a dependency in Xcode's Swift Package Manager, ensuring compatibility with your project's Swift version.
