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

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"];

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]

您可以在plist.info中指定CFBundleShortVersionString字符串，并使用提供的API以编程方式读取该字符串。

Swift版本分别为:

斯威夫特3

let versionNumber = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String
let buildNumber = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion") as! String

斯威夫特2

let versionNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as! String
let buildNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleVersion") as! String

它包括在这个回购，检查一下:

https://github.com/goktugyil/EZSwiftExtensions

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。
