iOS集成Atom支付网关遇问题：.a静态库配置及头文件找不到求助

Hey there, let's work through these issues step by step since you're new to static libraries on iOS!

1. Fixing the "nb.h not found" Error #

The missing header files issue usually happens when the library's headers aren't properly linked to your project. Here's what to check:

• Did you add the library's header files to your project? The .a file is just the compiled binary—you need the corresponding header files (like nb.h, card.h, etc.) to be present in your project. Double-check if the "payAtom" folder mentioned in the docs includes these .h files, and make sure you added the entire folder to your project's group.
• Update Header Search Paths:
  1. Go to your project's Build Settings.
  2. Search for Header Search Paths.
  3. Add the path to the folder containing the Atom SDK headers. For example, if you placed the headers in a payAtom folder at the root of your project, add $(PROJECT_DIR)/payAtom and check the Recursive box (this ensures subfolders are also scanned).
• Verify import syntax: You're already using #import "nb.h" (correct for project-local headers) instead of <nb.h> (which is for system frameworks), so that part is good—just make sure the path is right.

2. Understanding the "Copy Bundle Resources" Step #

The docs mention adding the resourcesLib Bundle to Copy Bundle Resources—here's what that means:

• This bundle contains necessary resources the Atom SDK needs at runtime, like payment UI icons, localized strings, configuration files, or other assets. Without adding it, the SDK might fail to load critical resources when processing payments.
• How to add it:
  1. In Xcode, go to your target's Build Phases tab.
  2. Find the Copy Bundle Resources section.
  3. Click the + button, then locate and select the resourcesLib.bundle file (it should be part of the SDK files you received from Atom).
• If you can't find this bundle, reach out to Atom's support team—they might have included it in a subfolder of the SDK package, or it could be a missing file in their initial delivery.

Additional Checks to Ensure Smooth Integration #

• Confirm the .a file is linked: Go to Build Phases > Link Binary With Libraries and make sure libAtomPayLib(Live).a or libAtomPayLib(UAT).a is listed there. If not, add it using the + button.
• Double-check Other Linker Flags: You've already added $(OTHER_LDFLAGS) -ObjC—this is crucial because the SDK uses Objective-C categories (like NSString+DES), and -ObjC forces the linker to load all Objective-C classes and categories from the static library, preventing runtime crashes from missing methods.
• Check architecture compatibility: Run lipo -info /path/to/libAtomPayLib(Live).a in Terminal to see which CPU architectures the library supports. Make sure your project's Build Settings > Architectures matches (e.g., if the library only supports arm64, set your project to use arm64 only).
