用分页添加UIScrollView到现有的UIViewController

我想添加一个UIScrollView与分页来通过我现有的视图控制器，这是我的应用程序的根视图不同的意见。 我也有标签栏和导航栏控制器。 我可以添加一个滚动视图到这个视图控制器来完成我想要的东西，如果是这样的话，有人可以指出我正确的方向如何去做？

这是我的视图控制器。

这对我来说真的很好：

为你的UIScrollView声明一个属性，并将你的ViewController设置为一个UIScrollViewDelegate

 @interface ViewController : UIViewController<UIScrollViewDelegate> @property (strong, nonatomic) UIScrollView *theScrollView; @end 

**请注意，我正在使用代码设置我的UIScrollView ，但可以使用XIB轻松完成。

在ViewController的viewDidLoad:

  self.theScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 50, self.view.frame.size.width, 300)]; self.theScrollView.delegate = self; self.theScrollView.pagingEnabled = YES; self.theScrollView.showsHorizontalScrollIndicator = NO; self.theScrollView.showsVerticalScrollIndicator = NO; [self.view addSubview:self.theScrollView]; NSArray *viewArray = [NSArray arrayWithObjects://your UIViews]; for(int i=0; i<viewArray.count; i++) { CGRect frame; frame.origin.x = self.theScrollView.frame.size.width * i; frame.origin.y = 0; frame.size = self.theScrollView.frame.size; UIView *subview = [[UIView alloc] initWithFrame:frame]; [subview addSubview:[viewArray objectAtIndex:i]]; [self.theScrollView addSubview:subview]; } self.theScrollView.contentSize = CGSizeMake(self.theScrollView.frame.size.width * viewArray.count, self.theScrollView.frame.size.height); 

大多数分页scrollViews也有一个UIPageControl与它关联。 为此，重写这个UIScrollViewDelegate方法：

 - (void)scrollViewDidScroll:(UIScrollView *)sender { CGFloat pageWidth = self.theScrollView.frame.size.width; int page = floor((self.theScrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1; self.thePageControl.currentPage = page; }

我可能会尝试使用UIPageViewController ，而不是一个普通的分页滚动视图。

Apple的PhotoScroller示例代码提供了一个非常好的如何使用UIPageViewController 。

我在github上也有一些修改PhotoScroller的代码来加载UIViewController子类中的UIPageViewController 。 （在Apple的示例代码中， UIPageViewController是根视图控制器。）

我从来没有用UIPageViewController与每个页面中的不同的UIViewController子类（PhotoScroller示例代码在所有页面中使用PhotoViewController ），但我不明白为什么它不能做的代码的一些修改。
