你可以使用infoDictionary从info中获取版本细节。这段代码适用于swift 3。只需调用此方法并在任何首选的UI元素中显示版本。

Swift-3  

func getVersion() -> String {
    let dictionary = Bundle.main.infoDictionary!
    let version = dictionary["CFBundleShortVersionString"] as! String
    let build = dictionary["CFBundleVersion"] as! String
    return "v\(version).\(build)"
}

如果你需要version和build num的组合，这里有一个使用Swift 3的简单方法:

let appVersion = Bundle.main.infoDictionary!["CFBundleShortVersionString"]!
let buildNum = Bundle.main.infoDictionary!["CFBundleVersion"]!
let versionInfo = "\(appVersion) (build \(buildNum))"
// versionInfo is now something like "2.3.0 (build 17)"

加一个a !String到appVersion或buildNum行的末尾，以仅获取该部分作为String对象。如果你想要完整的versionInfo，就不需要这样做了。

我希望这能有所帮助!

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

你可以尝试使用字典作为:-

NSDictionary *infoDictionary = [[NSBundle mainBundle]infoDictionary];

NSString *buildVersion = infoDictionary[(NSString*)kCFBundleVersionKey];
NSString *bundleName = infoDictionary[(NSString *)kCFBundleNameKey]

这就是我在申请中所做的

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

希望这个简单的答案能帮助到一些人……

斯威夫特5:

有两件事——应用版本和构建版本

获取App版本: if let appVersion = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as?字符串{ //当前appVersion } 获取构建版本: if let buildVersion = Bundle.main.infoDictionary?["CFBundleVersion"] as?字符串{ //当前buildVersion }
