如何使用Xcode 4.2和故事板使用“页面控制”？

Question

I'm trying to learn the basics of iOS programming and I was wondering how you would use a page control using Xcode 4.2 and storyboard? I'm subscribed to MyCodeTeacher.com and the lesson on Page Controllers is outdated and doesn't work with the new Xcode. I cant find a tutorial via Google and the Apple Documentation isn't helping either. Can someone point me to a good tutorial or give me a basic example?

Thank you SO much!

Answer 1

Ok here is a workflow for a typical case:

1.Create an IBOutlet for your pageControl object

Example:

@property (unsafe_unretained, nonatomic) IBOutlet UIPageControl *pageControl;

2.Create an IBAction as well for the "Value Changed" event of the same pageControl

Example:

-(IBAction)pageDidChange:(id)sender;

Every time the user changes the page now, your pageDidChange: method will be fired.

Now, here are some common methods:

1. Setup the number of pages

   [self.pageControl setNumberOfPages:6];

2. Set the current page

   [self.pageControl setCurrentPage:1];

I hope that this will get you started...

Answer 2

for adding view to each page use scrollview along with page control

- (IBAction)changePage {

CGRect frame;

    frame.origin.x = self.scrollView.frame.size.width * self.pageControl.currentPage;

 frame.origin.y = 0;

frame.size = self.scrollView.frame.size;

 [self.scrollView scrollRectToVisible:frame animated:YES];
}
