// Syncs with App Store and Xcode Project Settings Input
NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];

func getAppVersion() -> String {
    let dictionary = Bundle.main.infoDictionary!
    let versionValue = dictionary["CFBundleShortVersionString"] ?? "0"
    let buildValue = dictionary["CFBundleVersion"] ?? "0"
    return "\(versionValue) (build \(buildValue))"
}

基于@rajat chauhan的回答，没有强制转换为字符串。

获取X.Y.Z格式版本字符串的简单方法是:

[NSBundle mainBundle].infoDictionary[@"CFBundleVersion"]

或者，对于X.Y:

[NSBundle mainBundle].infoDictionary[@"CFBundleShortVersionString"]

这两个代码段都返回字符串，您可以将其分配给标签对象的文本属性，例如。

myLabel.text = [NSBundle mainBundle].infoDictionary[@"CFBundleVersion"];

阅读信息。你的应用程序的plist文件，并获得值的关键CFBundleShortVersionString。阅读信息。plist会给你一个NSDictionary对象

NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];

有两件事——构建版本和应用版本。

获取App版本: NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]; 获取构建版本: NSString *buildVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
