    My project is View based and contain 3 controller ,

    the first controller contain picker view if user select item from it.

    the second controller display.

    and the second controller contain button when user touch inside this button

    the three controller display.

    Now my problem I want hide the first controller when the second display

    hint : the first controller is UIViewController

    and SecondController is UINavigationController

    Can you supply more details on how you have your view hierarchy set up, as well as some code or the project? Then tell us what you have tried to do, and the outcome.

    I'm just going to mention that you show and hide views, not controllers.

    So it might look something like this:

    viewController.view.hidden = YES;

    Not like this:

    viewController.hidden = YES;

    Not really sure if that helps at all.

    Thanks a lot :eek:

    I try it but when select item from picker view in firstController the white screen display not secondController :confused:

    - (void)pickerView:(UIPickerView *)pickerView 
    	UINavigationController *navigController = [[UINavigationController alloc] init];
    	[self.view addSubview:navigController.view];
    	switch (row){
    		case 0: 
    		case 1: 
    			self.view.hidden = YES;
    			[secController displayMenu:1];
    			secController = [[SecondViewController alloc] init];
    		case 2:	
    			self.view.hidden = YES;
    			[secController displayMenu:2];
    			secController = [[SecondViewController alloc] init];

    Your life will be easier if you use the navigation controller for all your views. Start with the navbased app template. Then use pushViewController:animated: to make your additional view controllers appear.

    Many, many apps work like this.

    If I understand your question, if there is a picker view on the rootViewController it will be covered up when you push the second view controller.
