appdelegate shared instance delegate

Question

    MyAppDelegate *appD;        
    appD = [UIApplication sharedApplication];

    if(appD.sw1.on)
        NSLog(@"It is ON");
    else
        NSLog(@"It is OFF");

Gives no error while compiling. Runs without any warning, but it doesn't work.

I dont see what the problem is.

...

EDIT: OMG, should have called delegate method too:

appD = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];

I recommend you this method to share the app delegate: https://coderwall.com/p/z4h4uw?i=2&p=1&q=&t%5B%5D=%21%21mine&t%5B%5D=%21%21bookmarks
