objective c - How can I set a menu item click to respond to IBAction from another class? -

i'm pretty new xcode/objective-c/cocoa. want implement settings window app.

i have mainmenu.xib holds main window. menu, want open settings window. created settings.xib , appropriate .h , .m files hold window do.

settings.h:

#import <cocoa/cocoa.h> @interface settings : nswindowcontroller <nsapplicationdelegate> -(ibaction)opensettings:(id)senderid; @property (nonatomic, retain) settings *thiswindow; @end

settings.m:

#import "settings.h" @implementation settings - (void)windowdidload { [super windowdidload]; // implement method handle initialization after window controller's window has been loaded nib file. } // open preferences window - (ibaction)opensettings:(id)senderid { _thiswindow = [[settings alloc] initwithwindownibname:@"settings"]; [_thiswindow showwindow:self]; } @end

i dragged preferences menu item first responder, , selected opensettings: there. however, item still disabled , i'm pretty sure it's because did nil link settings interface mainmenu.xib, works appdelegate.h/m.

how create work? other solutions found didn't quite work me.

if understand clear want store mainmenu , mainwindowcontroller in 2 separate classes.

open main menu nib-file. remove window object tree. check in project settings -> general -> main interface still mainmenu (without .xib-extension). create (implement) custom mainwindowcontroller class (with nib-file may be). open appdelegate class. in - (void)applicationdidfinishlaunching:(nsnotification *)anotification method create instance of main window controller class, show window

use code below

mainwindowcontroller *controller=[[mainwindowcontroller alloc] initwithnibname:@"mainwindowcontroller"]; [controller showwindow:nil]; [controller.window makekeyandorderfront:nil];

here is.
