如何获取Info.plist文件信息

swift：

NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"]

比如：

        if let version = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as? String {            versionLabel.text = "Version. \(version)"        } else {            versionLabel.text = "Version. 1.0.0"        }
