objective c - NSWindowController showWindow only works once -

-

i have subclass of nswindowcontroller has own nib , class has ibaction show window , loads so.

if (!propertiescontroller){     propertiescontroller = [[propertiescontroller alloc] init]; } [propertiescontroller showwindow:self];

it first time after close window , call method again window not displayed. sure window not getting released. possibly have override showwindow order window front? or have specify window controller uses in nib?

have tried

[propertiescontroller.window makekeyandorderfront:self];

?
