There is one point of note:

Get version numberOne is called version, and one is called build, both of which can be selected in Xcode and click "Summary" to see. The key for version in the plist file is "cfbundleshortversionstring", which is the same as the version number on AppStore, and the key to build in Plist is "cfbundleversion". Represents the version number of build, which should be incremented by 1 after each build. Both of these values can be obtained in the program through the following code:1.Version nsstring *key = @ "cfbundleshortversionstring"; 2.buildnsstring *key =@ "cfbundleversion";

1. In APPDELEGATE.M
