从cmd + tab获取ProcessList

Question

I want to get the applications from the cmd+tab menu in OS X. The best way I got now is to associate this with a AppleScript call with the following:

NSDictionary *errorDict;
NSAppleEventDescriptor *returnValue;
NSString *appleScriptText = @"tell application \"System Events\" to get name of (processes where background only is false)";
NSAppleScript *script = [[NSAppleScript alloc] initWithSource:appleScriptText];

Then loop through the stuff coming back from it and to match it to the [[NSWorkspace sharedWorkspace] runningApplications] but this seems a little bit too weird to get this task done.

So my question here: is there a way that is not so quirky like this one?

I am really tense for the answers.

Answer 1

Given that you're already familiar with -[NSWorkspace runningApplications] , why don't you just iterate over those and check which ones meet your criteria? The background only property corresponds to NSRunningApplication 's activationPolicy property being something other than NSApplicationActivationPolicyRegular .

So, something like (not tested):

NSArray* apps = [[NSWorkspace sharedWorkspace] runningApplications];
NSIndexSet* indexes = [apps indexesOfObjectsPassingTest:^BOOL(id obj, NSUInteger idx, BOOL *stop){
    return [obj activationPolicy] == NSApplicationActivationPolicyRegular;
}];
NSArray* names = [[apps objectsAtIndexes:indexes] valueForKey:@"localizedName"];
