如何从xcode获取自己的应用程序版本？

Question

I wonder if there is a way to get your own app version in code after you put it in the "Summary" tab in xCode. One way seems to be to search Info.plist for CFBundleVersion key, but is there any other, easier, more convenient way?

Answer 1

You can find it in the main bundle. I think it's something like:

[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];

Answer 2

I typically use the Build number ( CFBundleVersion ) to keep track of, well, the number of builds, and the Version number ( CFBundleShortVersionString ) for marketing purposes. I use a run script to auto-increment my build number and I update the version number manually before each new release. So if you want to include the actual Version number in your code as opposed to the Build number, use this:

[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]

or

[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];

Here's the run script that increments the build number for anyone interested:

#!/bin/bash

buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "${PROJECT_DIR}/${INFOPLIST_FILE}")
buildNumber=$(($buildNumber + 1))
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "${PROJECT_DIR}/${INFOPLIST_FILE}"

Answer 3

NSString *version = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];

Answer 4

对于Swift：

Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString")
