代码中的 UIPageViewController 部分卷曲

Question

是否有可能使用 UIPageViewController 从代码中部分卷曲页面。我想向用户展示他能够更改页面，为此我想部分卷曲页面并将其放回原处（向左然后向右轻扫，这将是用户输入以获得此效果但我想从代码中得到它）。

Answer 1

你需要使用UIViewAnimationTransitionCurlUp. 查看下面的示例。

- (void)handleSwipe:(UISwipeGestureRecognizer *)sender {

if(sender.state == UIGestureRecognizerStateEnded) {
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3];
    [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:window cache:YES];

    [self.view addSubview:[newView view]];
    [oldView removeFromSuperview];

    [UIView commitAnimations];
   }                  
}
- (void)createGestureRecognizers:(UIView *) target {
UISwipeGestureRecognizer *rightSwipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];

[rightSwipeRecognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];
[target addGestureRecognizer:rightSwipeRecognizer];
[rightSwipeRecognizer release];
}
