Question

I have static library and my custom view controller inside (f.e mainVC).
My static library will be built in some third party application.

I have to show mainVC.view instantly after third app did launch.
I do:

[window addSubView:mainVC.view];

but how can I do my mainVC active? It means I have to deny landscape orientation in

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

and this method never calls in this case.

I’ve also tried to call manually

[self.mainVC viewWillAppear:NO];

but still unsuccessful.

Maybe I should use

-(void)presentModalViewController:animated

but it’s deprecated. And I have to support IOS 4.3

Answer 1

You might want to check if the class is allowed to respond to the method before you call it.

if([self respondsToSelector:@selector(presentViewController:animated:completion:)]) 
{
    [self presentViewController:viewController animated:YES];
}
else
{
    //some other methods
}

This way you can use the deprecated method for support with IOS 4.3, and use another solution for later IOS versions
