您在Xcode目标摘要的版本"字段中设置的值位于此处:
The value you set in the Xcode target summary's "Version" field is in here:
雨燕3
let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as! String
ObjC
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
雨燕2
let version = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as! String
和内部版本":
雨燕3
let build = Bundle.main.infoDictionary?[kCFBundleVersionKey as String] as? String
ObjC
NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleVersionKey];
雨燕2
let build = NSBundle.mainBundle().infoDictionary?[kCFBundleVersionKey as String] as! String
