問(wèn)題描述
UIPageViewController中是否可以通過(guò)編程方式翻頁(yè)?
Is it possible to turn page programmatically in UIPageViewController?
推薦答案
是的，方法是可以的:
- (void)setViewControllers:(NSArray *)viewControllers
direction:(UIPageViewControllerNavigationDirection)direction
animated:(BOOL)animated
completion:(void (^)(BOOL finished))completion;`
這與在頁(yè)面上設(shè)置第一個(gè)視圖控制器的方法相同.類似的，你可以用它去其他頁(yè)面.
That is the same method used for setting up the first view controller on the page. Similar, you can use it to go to other pages.
想知道為什么 viewControllers 是一個(gè)數(shù)組，而不是單個(gè)視圖控制器嗎?
Wonder why viewControllers is an array, and not a single view controller?
這是因?yàn)轫?yè)面視圖控制器可能有一個(gè)脊椎"(就像在 iBooks 中一樣)，一次顯示 2 頁(yè)內(nèi)容.如果您一次顯示 1 頁(yè)內(nèi)容，則只需傳入一個(gè) 1 元素?cái)?shù)組.
That's because a page view controller could have a "spine" (like in iBooks), displaying 2 pages of content at a time. If you display 1 page of content at a time, then just pass in a 1-element array.
Swift 中的一個(gè)例子:
An example in Swift:
pageContainer.setViewControllers([displayThisViewController], direction: .Forward, animated: true, completion: nil)
