Use of the iOS Static library (libarary)

(The account has been found, migrated back from the new blog)

Static libraries: A mechanism for sharing the same code in multiple application.

Build a single Viewcontroller project, and then right-build the new NewFile in the left sidebar->framwork&libarary->staticlibaray

The results of the completion are as follows:

Select Staticlibaray,cmd + B build, then the LIBSTATICLINARAY.A in the products will turn black, indicating that the compilation was successful.

Switch to project, add Libaray

The imported #import "StaticLibaray.h" still displays file not Found. This is because Iosstaticlibaray now has no StaticLibaray.h to search for. We need to set the header file search path for project.

Now you need to know the path to the static library, select Libstaticlibaray-> Show in Finder

This is the path of the point staticlibarary, we just add these to hears Search path, on different Macs this path is certainly not the same, so we need to use a few of the system's macros.

+ $ (built_products_dir)

Build/products/debug-iphoneos

Build after successful, the final product path--can be Build Settings of the parameter per-configuration Build Products Path set in the item

+ $ (target_name)

Target Project Name

+ $ (srcroot)

engineering documents (e.g. nuno.xcodeproj ) of the path

+ $ (current_project_version)

+ $ (inherited)

+ $ (build_dir) "/users/username/library/developer/xcode/deriveddata/project-dxdgjvgsvvbhow Gjqouevhmvgxgf/archiveintermediates/project Distribution/buildproductspath "

+ $ (build_root) "/users/username/library/developer/xcode/deriveddata/project-dxdgjvgsvvbhow Gjqouevhmvgxgf/archiveintermediates/project Distribution/buildproductspath "

+ $ (build_variants) Normal

+ $ (build_dir) "/users/username/library/developer/xcode/deriveddata/project-dxdgjvgsvvbhow Gjqouevhmvgxgf/archiveintermediates/project Distribution/buildproductspath "

+ $ (build_root) "/users/username/library/developer/xcode/deriveddata/project-dxdgjvgsvvbhow Gjqouevhmvgxgf/archiveintermediates/project Distribution/buildproductspath "

+ $ (build_variants) Normal

+ $ (effective_platform_name) ' Iphoneos ' or ' iphonesimulator

We now add $ (built_products_dir)/include/staticlibaray to the head Search Path debug, run no problem. Debug mode I believe has been resolved, the following see release mode

Now cut back to staticlibarary,product->archive.

And then to project, Product->archive found and not found file, because we haven't set the release path yet, so let's go find the path to the release.

/users/barryclass/library/developer/xcode/deriveddata/iosstaticlibarydemo-hitdffgifzihnjehziiwfvgvagxy/build/ Intermediates/archiveintermediates/staticlibaray/buildproductspath/release-iphoneos/include/staticlibaray

Refer to the above macro, we can write

$ (build_root)/release-{effective_platform_name}/include/staticlibaray/

We now add in Head Search Path release$ (built_products_dir)/include/staticlibaray, Archive no problem. G Fix it.

All of our settings are set in Project project, not in a single target, but can be set directly in target.

When set in Project, we add $ (inherited) to the corresponding item in target, which represents the inheritance of the settings in project.

If we create a new class in Staticlibaray, and then add the new. h file to the build phases, Copy files in Staticlibaray, then you can compile it and use it in project. But there is a new problem, as long as the static library changes we have to build a static library, so that the changes to take effect. If we make the static library a dependency on project, we don't have to manually build the static library, and build it automatically each time we build project.

Select Iosstaticlibararydemo, select Target---build phases, target Dependencies Click on the plus sign below to find that there is no static library we want to add. Don't worry, we just have to drag Staticlibaray into the Iosstaticlibarydemo.

This is then click the plus sign to add
