Animating simultaneously window and view frame in Cocoa

I need to animate a view frame size adding 100px of height, but I need the window grow up simultaneously with the view.

I tried with this code :

    //resize Window
    NSRect winsize = [window frame];
    win开发者_如何学Csize.size.height += 100;
    [self.window setFrame:winsize display:YES animate:YES];

    //resize View
    NSRect viewsize = [myview frame];
    viewsize.size.height += 100;
    [[myview animator] setFrame:viewsize];

It works but I obtain an ugly effect, Window and View had some delay in resize. Thus, I get the Window frame resizing before than the View frame. How can I modify my code to make them resizing simultaneously ?

add: I found this answer but it tdoesn't seems to work for me: Simultaneously modify window frame and view frame

I found a good solution: using autoresizingMask to mantain min and max Y Margin and allow height resize. [myview setAutoresizingMask:NSViewHeightSizable];
