Disable focus on second screen in objective-c - objective-c

Question

i have an app and i try it on multi screen. I have two screens and i want to disable focus on the second screen when the both sreens are enterFullscreen, i want to force the focus on the main screen.
I tried solutions i found here but doesn't change anything.
following code shows how i enterFullScreen for my mainWindow and my second Window
[self.window.contentView enterFullScreenMode:[[NSScreen screens] firstObject] withOptions:nil];
[windowArray insertObject:self.window atIndex:0];
NSRect screenRect;
NSArray *screenArray = [NSScreen screens];
for (NSInteger index = 1; index < [screenArray count]; index++)
{
NSScreen *screen = [screenArray objectAtIndex: index];
screenRect = CGRectMake(0, 0, screen.frame.size.width , screen.frame.size.height);
NSWindow *window = [[NSWindow alloc] initWithContentRect:screenRect styleMask:NSBorderlessWindowMask backing:NSBackingStoreBuffered defer:NO screen:screen];
[window.contentView setWantsLayer:YES];
window.contentView.layer.backgroundColor = [NSColor blackColor].CGColor;
[window.contentView enterFullScreenMode:[[NSScreen screens] objectAtIndex:index] withOptions:nil];
[windowArray addObject:window];
}
When both screens are in fullScreen mode, when i click on the second window i have the focus on the second window (normal event) but i want to disable that and force to put the focus on my main Window. I tried to disable mouse event on the second screen but.. not working.
If someone can help me ! thanks in advance

I don't know if it's the best answer for you, but you can iterate through all the subviews of the content view, and call setEnabled: on all of them. You can see a better and complete answer here: https://stackoverflow.com/a/16336624/2923506
for (NSView *object in [self.window.contentView subviews]) {
// Check it out the object
// set enable to NO [(id)object setEnabled:NO];
}
