从MyProject-App.xml中检测versionNumber？Adobe AIR

Question

我正在开发的桌面应用程序正在Adobe AIR + Flex + As3中开发.现在,我想检测AIR应用程序随附的XML描述文件中的versionNumber参数.

<!-- A string value of the format <0-999>.<0-999>.<0-999> that represents application version which can be used to check for application upgrade. 
Values can also be 1-part or 2-part. It is not necessary to have a 3-part value.
An updated version of application must have a versionNumber value higher than the previous version. Required for namespace >= 2.5 . -->
<versionNumber>1.0.0</versionNumber>

是否有可用于访问此变量或属性的变量或属性？例如,在应用程序的"关于"框中,我希望它依赖于此版本,而不是手动编辑显示的版本.

Answer 1

  var appXML:XML =  NativeApplication.nativeApplication.applicationDescriptor;

你可以解析这个xml的版本号,就像这样

var ns:Namespace = appXML.namespace();
trace(appXML.ns::versionNumber);
