推荐答案

可以使用Spotlight API获取所有应用程序文件.具体来说，是NSMetadataQuery类.

It is possible to get all the app files using the spotlight API. Specifically, NSMetadataQuery class..

-(void)doAQuery {
    query = [[NSMetadataQuery alloc] init];
   // [query setSearchScopes: @[@"/Applications"]];  // If you want to find applications only in /Applications folder

    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"kMDItemKind == 'Application'"];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(queryDidFinishGathering:) name:NSMetadataQueryDidFinishGatheringNotification object:nil];
    [query setPredicate:predicate];
    [query startQuery];
}

-(void)queryDidFinishGathering:(NSNotification *)notif {
    int i = 0;
    for(i = 0; i< query.resultCount; i++ ){
        NSLog(@"%@", [[query resultAtIndex:i] valueForAttribute:kMDItemDisplayName]);
    }
}

您还有其他各种属性，例如 kMDItemFSName .在此处

You have various other attributes, such as kMDItemFSName. More attributes can be found here

上述终端版本为:

mdfind 'kMDItemKind=Application'
