推荐答案

你会想要使用 UIScrollView，然后，作为兄弟，将 UIPageControl 放置在它上面.然后将您的每个页面放入滚动视图并为其打开分页.这样，每次轻弹"都会将滚动视图移动一页.

You'll want to use a UIScrollView, and then, as a sibling, position the UIPageControl over it. Then put each of your pages into the scroll view and turn paging on for it. This way each 'flick' will move the scroll view one page over.

现在，将您的视图控制器指定为滚动视图的代理，并注意 scrollViewDidEndScrollAnimation，并使用 contentOffset 来确定当前页面.

Now, assign your view controller to be the delegate of the scroll view, and watch for scrollViewDidEndScrollAnimation, and use the contentOffset to determine which page is current.
