cocoa - 如何从 Cocoa 中的应用程序名称获取 bundle 标识符？

Question

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

Answer 1

以下方法将返回指定应用程序的应用程序包标识符:

- (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，您可以像这样调用该方法:

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

appID 现在包含 com.apple.mail

swift 5.1

import AppKit

func bundleIdentifier(forAppName appName: String) -> String? {

    let workspace = NSWorkspace.shared
    let appPath = workspace.fullPath(forApplication: appName)
    if let appPath = appPath {
        let appBundle = Bundle(path: appPath)
        return appBundle?.bundleIdentifier
    }
    return nil
}

// For Mail you can call the method like so:

let appID = bundleIdentifier(forAppName: "Mail")

弃用

fullPathForApplication:/fullPath(forApplication:) 方法已在 macOS 10.15 中弃用 - 目前尚不清楚 future 的答案是什么。
