How to Write a Pod and publish it to CocoaPods?

This article describes how to write a pod by yourself, register it on CocoaPods, and put the code on Github for others to download. This is basically the "standard" mounting process for any pod. Of course, you can also put the

What is pod? This is a problem. I can hardly find two identical answers.
From ISO/IEC 14882: 2003 (e) p153:
... A pod-struct is an aggregate class that has no non-static data members of type non-pod-struct,
Non-pod-Union (OR array of such types) or reference, and has no user-defined copy assignment operator
And no use
Contact pod later found to use it to manage the third-party code is very convenient, after the creation of their own modules to put on the idea of the pod, after a series of Baidu and Google, basically achieved, the following is my realization of the steps and understanding:Standard POD usage processand ours is this.I.

first introduce what k8s is: (Quote from k8s Chinese community)Kubernetes is a container cluster management system, it is an open source platform, can realize the automatic deployment of container cluster, auto-scaling capacity, maintenance and other functions. Kubernetes you can:
Quick Deploy app
Rapid extension Application
Seamless docking of new application features

You can think of the pod type as a data type packaged with a green protective layer from outer space. The pod means "plain old data, that's "Full old data !) This is the meaning of the pod type. Its exact definition is quite rough (see the C ++ ISO standard). It basically means that the pod type contains raw data compa
destructor call Writeprofileint writes this value to the user profile. When the dialog box starts, Cpersistopendlg sends itself an initialization message that calls Getprofileint to read from disk the values stored in the configuration file and set the view mode. PostMessage must be invoked because regular initialization messages wm_initdialog and Cdn_initdone come before the file dialog is fully initialized-for an explanation of this, see the March column.
By the way, you should use GETPROFIL

Pod type concept
Problem:In C ++, the derived virtual function cannot be called from the constructor of a class, because the virtual table has not yet been fully created. But in C #, it seems like we can. Is that true? Why is there such a difference?Clifton F. VaughnAnswer:Indeed, C # And C ++ are different in this respect. In C ++, if you call a virtual

Pod type (plain old data), which I saw in Morden C ++ design for the first time. To be honest, this is indeed a good book with amazing techniques. The pod type is mentioned in this section. This type is compatible with the C language struct and is mainly used when the pod object (especially the array) is being copied, you can directly use the memcpy function to i
Pod is the most basic deployment dispatch unit in Kubernetes, and it can contain container, which logically represents an instance of a certain application. For example, a Web site application is built from the front end, back end, and database, and these three components will run in their respective containers, so we can create a pod containing three container.
