UIPageViewController上的圆角

Question

我想知道是否有人能够成功地将UIPageViewController的角落（iBooks的动画书转动为圆角）？

我尝试了这个但无济于事：

[self.notebookPages setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:NULL];
self.notebookPages.dataSource = self.pageModelController;
self.notebookPages.doubleSided = NO;
[self addChildViewController:self.notebookPages];

    // mask

    CAShapeLayer *maskLayer = [CAShapeLayer layer];
    UIBezierPath *roundedPath = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(0, 0, 332, 480)
                                                      byRoundingCorners:UIRectCornerTopRight | UIRectCornerBottomRight
                                                            cornerRadii:CGSizeMake(15.f, 15.f)];
    maskLayer.fillColor = [[UIColor whiteColor] CGColor];
    maskLayer.backgroundColor = [[UIColor clearColor] CGColor];
    maskLayer.path = [roundedPath CGPath];

self.notebookPages.view.layer.mask = maskLayer;

[self.notebookScrollNavigationController.notebook.pages addSubview:self.notebookPages.view];

self.notebookPages.view.frame = CGRectMake(0, 0, 332, 480);
[self.notebookPages didMoveToParentViewController:self];

这有点硬编码（这显然很糟糕），但我只是试图找出圆角是否有效。但是，我只得到一个非圆形的透明角落：

添加此导入：

#import <QuartzCore/QuartzCore.h>

现在你可以使用cornerRadius：

self.notebookPages.view.layer.cornerRadius = 6;
