Question

I have 5 different views and when I tap the button, I want to push one of 5 views randomly. However, I do not want to make 5 different controllers for each views. Do I have a chance to put them in one controller? If so, how?

You can have as many views as you want in a single UIViewController subclass. You can create them all in Interface Builder as well, in the one .xib file for your UIViewController class (it might get a bit hard to see, though, better to lay out each UIView in its own .xib). You can present them in any combination you want. Assuming you want to just show one view at a time, you can do this:

In your viewDidLoad method, start out showing the initial view, and in your class keep track of which is the current view:

...
@property(nonatomic, retain) UIView *currentView;
...
- (void)viewDidLoad 
{
    [self.view addSubview:self.defaultView];
    self.currentView = self.defaultView;
}

Then to switch to a particular other view do this:

- (void) switchToView:(UIView *)newView
{
    [self.currentView removeFromSuperView];
    [self.view addSubview:newView];
    self.currentView = newView;
}


}

Or you can show them all at one time: just [self.view addSubview:theView];
