How to get default LandscapeLeft Orientation in iOS5?

Question

Sorry if this question is duplicate, but I can't find the same solution. In iOS6, if I want to set default orientation for one UIViewController, I just use:

- (BOOL)shouldAutorotate {
    return YES;
}
- (NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskLandscapeLeft;
}

But how to do same in iOS5, I test both:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft);//not default
}
and
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return (toInterfaceOrientation == UIInterfaceOrientationMaskLandscapeLeft);// = return NO;
}

But the default orientation always Portrait.Any suggestion?

Answer 1

call the below method where you want to check the status of orientation.happy coding :-)

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    [self CheckForViewForOrientation:toInterfaceOrientation];
}

- (void) CheckForViewForOrientation:(UIInterfaceOrientation)orientation
{
    if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
    {
        //Ur lable portrait view
    }
    else if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight)
    {
        //Ur lable for landscape view
    }
}

Answer 2

If you want to achieve this for whole application, change supported orientation UISupportedInterfaceOrientations in app.plist file

Answer 3

- (BOOL)shouldAutorotate {

UIInterfaceOrientation orientation = [[UIDevice currentDevice] orientation];

if (orientation==UIInterfaceOrientationPortrait) {
 // do some 

}

return YES;
}

Include both the methods to support both 5 and 6

Answer 4

You need to provide

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
     UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

for that single View controller.
