Installation and use of Cocoa pods

principle

Cocoapods principle, it is to put all dependent libraries into another named Pods project, and then let the main project depends on the pods project, so that the source management work from the main project moved to the PODS project

• 1, Pods project will eventually compile into a file named Libpods.a, the main project only need to rely on this. a file.
• 2. For resource files, Cocoapods provides a bash script called pods-resources.sh, which executes every time the project is compiled and copies the various resource files from the third-party library to the target directory.
• 3, cocoapods through a file called Pods.xcconfig to set all the dependencies and parameters at compile time.
  • Attention
  • About. Gitignore
    After you perform the pod install, Cocoapods will generate a file named Podfile.lock, except for Podfile, and you should not add the file to the. Gitignore. Because Podfile.lock locks the version of the current dependent library, if the pod install does not change the version more than once, the pod update will change podfile.lock. When many people collaborate, you can prevent third-party libraries from being upgraded with inconsistent versions of your third-party libraries.

Common directives

1.pod Install --no-repo-update (disable index update operation) pod update --no-repo-update2. Pod serach:' pod search afnetworking '3. Pod outdated:' Check for updates to each third-party library '4. Pod init: Automatically generates a podfile file and initializes 5. Vim edit mode, input i enter edit, press ESC to exit edit, press:, enter WQ back to console

Problems that you may encounter

(1) Using Cocoapods to import a third-party class library does not have code hints?
Workaround: Select Target, Build Settings menu, find \ "User Header Search paths\" setting entry, add a value of "${srcroot}" and select \ "Recursive\"

(2) The following warning appears
[!] Your Podfile has had smart quotessanitised. To avoid issues on the future, you should not use TextEdit forediting it. If you is not using the TextEdit, you should turn off smart quotes Inyour editor of choice.
Workaround: Do not use text editing to edit podfile, use Xcode to edit, or use the terminal to tap commands to edit.

(3) After the pod install or pod Update command is executed, updating local specsrepositories is stuck
Workaround: Pod Install is wall, replace with new command pod install--verbose--no-repo-update

(4) Project run times error: Thefile "pods.xcconfig" couldn ' t be opened because there is no such file.
WORKAROUND: Pod update is available.

If more than one class library relies on the same class library, but relies on different versions, Cocoapods automatically sets a compatible version. GenevaDownload dependency: Download the specified version of the class library to a local project, based on the results of the analysis dependency.GenevaBuild a Pods project: Create a Pods project that is designed to compile and manage third-party frameworks, Cocoapods will add the required frameworks, libraries, and so on to the project, and configure them accordingly.GenevaConsolidate PODS projects: integrate pods and projects into one workspace, and set up file links.
