NSButton doesn't respond

I'm now developing mac application for the first time. So here's my problem. At first time launch, the application shows login form inside a custom view in the main menu xib file, the login form is loaded from another NSViewController file. The problem is when I click the button at login form which is loaded in the main menu, it doesn't respond on click event. I've tried using performselector method, add Action, also using IBAction, none of them works.

Here's the code of appdelegate.m

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    // Insert code here to initialize your application
    NSViewController *loginformcontroller = [[LoginViewController alloc]initWithNibName:@"LoginViewController" bundle:nil];
    [window setContentView:loginformcontroller.view];
}

and at LoginViewController.m

@implementation LoginViewController @synthesize usernametxt,passwordtxt,loginbtn;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Initialization code here.
        [loginbtn setAction:@selector(checkalogin)];
    }
    return self;
}
-(void)checkalogin{
    NSLog(@"masuk");
}

Any suggestions?

I don't know if it is the same case as mine , but if you extend that NSButton and you override some of the methods like (void)mouseDown:(NSEvent *)theEvent; do not forget to call [super mouseDown:event]

I assume loginbtn has its equivalent in Interface Builder. If so, justctrl+drag from button to view controller to create an IBACTION. No need to add action in code.

You seem to be dynamically setting an action for a button loaded from a nib.

It is possible that you have not actually hooked up the button to an IBOutlet in the view controller, which means that you are setting a target action for a nil object.

A better way would be to hookup of the buttons action to the correct method from within Interface Builder itself.
