Question

Before iOS 8, we used below code in conjunction with supportedInterfaceOrientations and shouldAutoRotate delegate methods to force app orie

Answer 1

I have tried many solutions, but the one that worked for is the following:

There is no need to edit the info.plist in ios 8 and 9.

- (BOOL) shouldAutorotate {
    return NO;
}   

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    return (UIInterfaceOrientationPortrait | UIInterfaceOrientationPortraitUpsideDown);
}

Possible orientations from the Apple Documentation:

UIInterfaceOrientationUnknown

The orientation of the device cannot be determined.

UIInterfaceOrientationPortrait

The device is in portrait mode, with the device held upright and the home button on the bottom.

UIInterfaceOrientationPortraitUpsideDown

The device is in portrait mode but upside down, with the device held upright and the home button at the top.

UIInterfaceOrientationLandscapeLeft

The device is in landscape mode, with the device held upright and the home button on the left side.

UIInterfaceOrientationLandscapeRight

The device is in landscape mode, with the device held upright and the home button on the right side.
