来源：互联网发布：js 封装自定义组件编辑：程序博客网时间：2024/05/23 01:27

我们可以通过包的信息的数据字典得到应用的版本 CFBundleVersion = "1.3";

let key ="CFBundleVersion"

// 获得当前软件的版本号

let currentVersion = NSBundle.mainBundle().infoDictionary![key]?.integerValue

// 打印当前软件版本信息

print(NSBundle.mainBundle().infoDictionary)

NSLog(@"ios 应用发布后 .app 应用文件路径::%@",[NSBundle mainBundle] );

NSLog(@"ios 应用发布后 .app 应用包(文件) 的详细信息 ::%@",[[NSBundle mainBundle] infoDictionary]);

[[NSBundle mainBundle] infoDictionary] 返回的是一个数据字典内容如下：

Optional(["CFBundleExecutable": WBBaiSiDemo, "DTPlatformVersion": 9.2, "UISupportedInterfaceOrientations": (

UIInterfaceOrientationPortrait

), "UILaunchImages": (

UILaunchImageMinimumOSVersion = "8.0";

UILaunchImageSize = "{414, 736}";

{

UILaunchImageMinimumOSVersion = "8.0";

UILaunchImageName = "Brand Assets-800-667h";

UILaunchImageOrientation = Portrait;

UILaunchImageSize = "{375, 667}";

{

UILaunchImageName = "Brand Assets-700";

UILaunchImageOrientation = Portrait;

UILaunchImageSize = "{320, 480}";

UILaunchImageOrientation = Portrait;

UILaunchImageSize = "{320, 568}";
