Is it possible to change orientation with a button event but disable auto rotate?

Question

I use codes below to change orientation of a view controller:

[[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIDeviceOrientationLandscapeLeft] forKey:@"orientation"];

It can force orientation to landscape, but I can not make it work with disabling auto rotate:

-(BOOL)shouldAutorotate {
    return NO;
}

Is this possible to change orientation with a button event but disable auto rotate?

Answer 1

Declare a boolean variable check and then on the basis of the value you can enable or disable orientaion.

   - (IBAction)someButton:(id)sender {
       [self changeOrientation];
            }

    -(void)changeOrientation
    {
        check = true;
        [[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIDeviceOrientationLandscapeLeft] forKey:@"orientation"];

    }

    -(BOOL)shouldAutorotate {
        if (check) {
            return YES;
            check = false;

        }
        return NO;
    }
