Creating a Cocoa application without NIB files

Question

Yes, I know this goes against the whole MVC principle!

However, I\'m just trying to whip up a pretty trivial application - and I\'ve pretty much implemented it. Howe

Answer 1

7 years too late to the party, but a bit simpler single file code

#import 

@interface AppDelegate : NSObject  {
    NSWindow* window;
}
@end

@implementation AppDelegate : NSObject
- (id)init {
    if (self = [super init]) {
        window = [NSWindow.alloc initWithContentRect: NSMakeRect(0, 0, 200, 200)
                                           styleMask: NSWindowStyleMaskTitled | NSWindowStyleMaskClosable
                                             backing: NSBackingStoreBuffered
                                               defer: NO];
    }
    return self;
}

- (void)applicationWillFinishLaunching:(NSNotification *)notification {
    window.title = NSProcessInfo.processInfo.processName;
    [window cascadeTopLeftFromPoint: NSMakePoint(20,20)];
    [window makeKeyAndOrderFront: self];
}

@end

int main(int argc, const char * argv[]) {
    NSApplication* app = NSApplication.sharedApplication;
    app.ActivationPolicy = NSApplicationActivationPolicyRegular;
    NSMenuItem* item = NSMenuItem.new;
    NSApp.mainMenu = NSMenu.new;
    item.submenu = NSMenu.new;
    [app.mainMenu addItem: item];
    [item.submenu addItem: [[NSMenuItem alloc] initWithTitle: [@"Quit " stringByAppendingString: NSProcessInfo.processInfo.processName] action:@selector(terminate:) keyEquivalent:@"q"]];
    AppDelegate* appDelegate = AppDelegate.new; // cannot collapse this and next line because .dlegate is weak
    app.delegate = appDelegate;
    (void)app.run;
    return 0;
}
