UIPageViewController with static content - ios

Question

I want to put some static content (buttons, views etc) on UIPageViewController. But I don't know how.
Any ideas?

Answer 1

Just create a container uiviewcontroller that will have e.g. a static button and an empty uiview. Create them as iboutlets and a usual property UIPageViewController called pvc. Then you can create a pvc in code and add it to the uiview outlet via addSubview:.
This is some code copied from a project i did last weeek. There are Skidata in a UIPageViewController and put an UIImage of a snowflake as overlay about it. I copied only the relevant parts of code. Hope this will help you:

SkiSubViewController *childViewController = [[SkiSubViewController alloc] initWithNibName:#"SkiSubViewController" bundle:nil];
childViewController.indexNumber = index;
if(self.skiDataArray)
{
childViewController.skiData = self.skiDataArray[index];
}
return childViewController;
