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)"
}

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"];

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

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 }

非常感谢布拉德·拉森(brad Larson)

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]

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"];
