How can i change the device orientation on button click without rotating the device

i want to change the device orientation on button click without rotating the device.

HERE IS MY CODE:

-(void)funcLandscapeBtnTapped:(UIButton *)button
{ 
      [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:NO];
}

Thanks in advance.

try this code, its working,

Your's Button Action:

isEnablePortraidMode = true;
NSNumber *number = [NSNumber numberWithInt:UIDeviceOrientationLandscapeLeft];
NSNumber *StatusBarOrientation = [NSNumber numberWithInt:UIInterfaceOrientationMaskLandscapeLeft];
[UIViewController attemptRotationToDeviceOrientation];
[[UIDevice currentDevice] setValue:number forKey:@"orientation"];
[[UIApplication sharedApplication] performSelector:@selector(setStatusBarOrientation:) withObject:StatusBarOrientation];
[UIViewController attemptRotationToDeviceOrientation];

and Add this method in Appdelegate

- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
    if(isEnablePortraidMode)
    {
        return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscape;
     }
    else
    {
         return UIInterfaceOrientationMaskPortrait;
    }
}
