iOS 应用程序，以编程方式获取构建版本

Question

有没有办法以编程方式获取我的应用的构建版本？我需要能够检测到用户何时通过 AppStore 更新了应用，以便执行一些代码进行调整

Answer 1

您在 Xcode 目标摘要的“版本”字段中设置的值在这里:

swift 3

let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as! String

ObjC

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

swift 2

let version = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as! String

和“构建”:

swift 3

let build = Bundle.main.infoDictionary?[kCFBundleVersionKey as String] as? String

ObjC

NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleVersionKey];

swift 2

let build = NSBundle.mainBundle().infoDictionary?[kCFBundleVersionKey as String] as! String
