这个问题困扰了我两天，以为无解了，看了一天的英文资料，最后发现这是apple的BUG！shit
解决方案是这样：连续调用setViewController两次。

解决方案是这样：连续调用setViewController两次。
__weak UIPageViewController* pvcw = pvc;
[pvc setViewControllers:@[page]
direction:UIPageViewControllerNavigationDirectionForward
animated:YES completion:^(BOOL finished) {
UIPageViewController* pvcs = pvcw;
if (!pvcs) return;
dispatch_async(dispatch_get_main_queue(), ^{
[pvcs setViewControllers:@[page]
direction:UIPageViewControllerNavigationDirectionForward
animated:NO completion:nil];
});
}];
对于苹果的这种BUG，我只能表示蛋疼！如果你要学习UIPageViewController，在xcode中新建一个page Based工程就是了。[pvc setViewControllers:@[page]
direction:UIPageViewControllerNavigationDirectionForward
animated:YES completion:^(BOOL finished) {
UIPageViewController* pvcs = pvcw;
if (!pvcs) return;
dispatch_async(dispatch_get_main_queue(), ^{
[pvcs setViewControllers:@[page]
direction:UIPageViewControllerNavigationDirectionForward
animated:NO completion:nil];
});
}];
