Mac App的Focus Finder

Question

我的mac应用程序中有一个小更新程序,它会自动下载带有最新版本应用程序的dmg文件.现在它也可以打开这个文件,但是如何关注Finder窗口呢？否则,用户不会知道狗文件被打开,因为它在后台.这是我下载和打开文件的代码:

NSData *fileData = [NSData dataWithContentsOfURL:
                       [NSURL URLWithString:@"http:// ... .dmg"]];
    if([fileData writeToFile:@"/file.dmg" atomically:NO]) {
        [[NSWorkspace sharedWorkspace] openFile:@"file.dmg"];
        // Here I want to focus the new Finder window which has been opened by the code above
exit(1);
    }

Answer 1

你可以使用

[[NSWorkspace sharedWorkspace] openFile:myFile withApplication:@"Finder"];
