我想实现UIPageViewController，我相信，我在最后阶段。 起初UIPageViewController只用一个VC滚动到一个“与众不同”的页面。 现在，我希望它不同ViewControllers之间滚动。 这是我使用的代码：
- (void)viewDidLoad {
[super viewDidLoad];
self.vcIdentifiers = @[@"PageContentViewController", @"PageContentViewController1"];
// Create page view controller
self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageViewController"];
self.pageViewController.dataSource = self;
UIViewController *startingViewController = [self viewControllerAtIndex:0];
NSArray *viewControllers = @[startingViewController];
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];
self.pageViewController.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height - 30);
[self addChildViewController:_pageViewController];
[self.view addSubview:_pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];
}
- (PageContentViewController *)viewControllerAtIndex:(NSUInteger)index
{
if (([self.vcIdentifiers count] == 0) || (index >= self.vcIdentifiers.count)) {
return nil;
}
// Create a new view controller and pass suitable data.
PageContentViewController *pageContentViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageContentViewController"];
pageContentViewController.titleText = self.pageTitles[index];
pageContentViewController.pageIndex = index;
return pageContentViewController;
}
我相信这是在viewControllerAtIndex我需要做出一些改变。 我想这样做的：
PageContentViewController *pageContentViewController = [self.storyboard instantiateViewControllerWithIdentifier:self.vcIdentifiers[index]];
但后来它仍然会初始化PageContentViewController。 所以我的问题是我不知道如何初始化不同ViewControllers。
