App listing version number configuration considerations: Cfbundleversion and Cfbundleshortversionstring settings, as well as internal check version updated code

First, cfbundleversion and cfbundleshortversionstring settings

Cfbundleversion: Identifies the build number, and can change the build number in a timely manner if the wrong revocation occurs.

Cfbundleshortversionstring: Represents the release version number of the app, and the version number is a string of three-time-delimited integers. The first integer represents a substantially modified version, such as a revision that implements a new feature or a major change. The second integer represents the revision to achieve a more prominent feature. The third integer represents a maintenance version.

such as : Version corresponds to the cfbundleshortversionstring release version number, such as the current version of 1.0.0 after you can change the time you update to 1.0.1)

build corresponds to the cfbundleversion (build number, to record the development version, each update needs to be higher than the previous high, such as: The current version is 1.0.1.1, the next can be changed to: 1.0.1.2)

Second, internal check version updatefrom the above configuration information, to check the version of the update needs to compare the current version and the version number returned by the request, if not the same update, if the same is not updated;when requesting the URL URLs in the code above, the data in the Jsondic dictionary is as follows:

Finally, it is important to remember that: when the version number obtained from the network interface is compared with the local version number, it must be used: cfbundleshortversionstring, otherwise it will cause errors.
