UIPageViewController子视图控制器之间的水平填充

问题描述

我正在使用UIPageViewController来显示嵌入在子视图控制器中的图像。

  NSDictionary * options = [NSDictionary dictionaryWithObject： [NSNumber numberWithInteger：UIPageViewControllerSpineLocationMin] forKey：UIPageViewControllerOptionSpineLocationKey]; 
 self.pageViewController = [[UIPageViewController alloc] initWithTransitionStyle：UIPageViewControllerTransitionStyleScroll navigationOrientation：UIPageViewControllerNavigationOrientationHorizo​​ntal options：options]; 
 self.pageViewController.dataSource = self; 
 self.pageViewController.view.frame = self.view.bounds; 
 
 ImageViewController * initialViewController = [self viewControllerAtIndex：0]; 
 initialViewController.index = 0; 
 
 NSArray * viewControllers = [NSArray arrayWithObject：initialViewController]; 
 [self.pageViewController setViewControllers：viewControllers方向：UIPageViewControllerNavigationDirectionForward动画：NO completion：nil]; 
 
 [self addChildViewController：self.pageViewController]; 
 [self.view addSubview：self.pageViewController.view]; 
 [self.pageViewController didMoveToParentViewController：self]; 
  

一切都很好但我讨厌儿童视图控制器彼此相邻。

我想知道是否有办法在子视图控制器之间添加填充，这样它们就不会彼此相邻。

看起来更像这样的东西：

解决方案

检查UIPageViewController初始化方法

- （id）initWithTransitionStyle：（UIPageViewControllerTransitionStyle）样式navigationOrientation：（UIPageViewControllerNavigationOrientation）navigationOrientation选项：（NSDictionary *）opt

您可以在 UIPageViewControllerOptionInterPageSpacingKey opt >

I am using UIPageViewController to display images that are embedded in child view controllers.

NSDictionary *options = [NSDictionary dictionaryWithObject: [NSNumber numberWithInteger:UIPageViewControllerSpineLocationMin] forKey: UIPageViewControllerOptionSpineLocationKey];
self.pageViewController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options: options];
self.pageViewController.dataSource = self;
self.pageViewController.view.frame = self.view.bounds;

ImageViewController *initialViewController = [self viewControllerAtIndex:0];
initialViewController.index = 0;

NSArray *viewControllers = [NSArray arrayWithObject:initialViewController];
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

[self addChildViewController:self.pageViewController];
[self.view addSubview:self.pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];

Everything works great but I hate that the child view controllers are right next to one another.

I was wondering if there was a way to add padding between the child view controllers so that way they're not right next to one another.

Something that would look more like this:

解决方案

check UIPageViewController init method

- (id)initWithTransitionStyle:(UIPageViewControllerTransitionStyle)style navigationOrientation:(UIPageViewControllerNavigationOrientation)navigationOrientation options:(NSDictionary *)opt

you can pass your inter page space value to opt in UIPageViewControllerOptionInterPageSpacingKey
