1st view controller is portrait mode and 2nd view controller in landscape mode.

I don’t want to change their orientation even when i rotate my iPhone.
How can i make?

Answer 1

In the Xcode, highlight the project in the Project Navigator, and select the target in the project tree. Open the Summary page, and go to the Supported Interface Orientations section. Un-click the orientations that you do not want your application to support.

In the story board, choose your first view controller, go to the Attributes inspector, and set orientation to “Portrait” in the Simulated Metrics section. Now choose the second view controller, and set its orientation to “landscape”.

In the view controller code, implement

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

for the first view controller, and

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

for the second view controller. This should fix the problem for you.
