Question

假设您有一个应用程序的名称Mail.app，您如何从应用程序名称以编程方式获取com.apple.mail？

Answer 1

以下方法将为命名应用程序返回应用程序的Bundle Identifier：

- (NSString *) bundleIdentifierForApplicationName:(NSString *)appName
{
    NSWorkspace * workspace = [NSWorkspace sharedWorkspace];
    NSString * appPath = [workspace fullPathForApplication:appName];
    if (appPath) {
        NSBundle * appBundle = [NSBundle bundleWithPath:appPath];
        return [appBundle bundleIdentifier];
    }
    return nil; 
}

对于Mail，你可以这样调用方法：

NSString * appID = [self bundleIdentifierForApplicationName:@"Mail"];

appID现在包含com.apple.mail

扩展Francesco Germinara在Swift 4中的回答，macOS 10.13.2：

extension Bundle {
    class func bundleIDFor(appNamed appName: String) -> String? {
        if let appPath = NSWorkspace.shared.fullPath(forApplication: appName) {
            if let itsBundle = Bundle(path: appPath) { // < in my build this condition fails if we're looking for the ID of the app we're running...
                if let itsID = itsBundle.bundleIdentifier {
                    return itsID
                }
            } else {
                //Attempt to get the current running app.
                //This is probably too simplistic a catch for every single possibility
                if let ownID =  Bundle.main.bundleIdentifier {
                    return ownID
                }
            }
        }
        return nil
    }
}

将它放在你的Swift项目中，你可以这样称呼它：

let id = Bundle.bundleIDFor(appNamed: "Mail.app")

或

let id = Bundle.bundleIDFor(appNamed: "Mail")

Answer 3

它是Contents / Info.plist中键CFBundleIdentifier的值

Answer 4

这是一种可能的快速实施

func bundleIdentifierForApplicationName(appName : String) -> String
{
    var workspace = NSWorkspace.sharedWorkspace()
    var appPath : String = workspace.fullPathForApplication(appName)
    if (appPath != "") {
        var appBundle : NSBundle = NSBundle(path:appPath)
     return appBundle.bundleIdentifier
    }
   return ""
}
