iphone - UIPageViewController 上的圆角

Question

我想知道是否有人成功地将 UIPageViewController(iBooks 的精美翻书动画)的角更改为圆角？

我试过了，但没有用:

[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)，但我只是想看看圆角是否可行。但是，我只得到一个非圆形的透明角:

添加这个导入:

#import <QuartzCore/QuartzCore.h>

现在你可以使用角半径了:

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