ios UIPageViewController，如何消除底部的差距？

Question

如何删除pageViewController的底部空间？

所以它可以显示图像上的控件图标而不是黑色空间..

Answer 1

this post中提到了几种解决方案！它们是：将转换样式从UIPageViewControllerTransitionStyleScroll切换到UIPageViewControllerTransitionStylePageCurl或在viewDidLoad中实现以下代码：

NSArray *subviews = self.pageController.view.subviews;
UIPageControl *thisControl = nil;
for (int i=0; i<[subviews count]; i++) {
    if ([[subviews objectAtIndex:i] isKindOfClass:[UIPageControl class]]) {
        thisControl = (UIPageControl *)[subviews objectAtIndex:i];
    }
}

thisControl.hidden = true;
self.pageController.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height+40);

它会自动隐藏pageControl指示符。
