我试图在 rootViewController 的 subview 中显示整个 pageContentView。我能够看到 pageView，但它不会正确地自动调整大小以适应 SubView，它只显示 pageContentView 的截断部分

这是它的样子

它应该是这样的

我不知道如何调整 pageView 的大小以使其在 subview 中正确显示。

Root View Controller .h

#import <UIKit/UIKit.h>
#import "PageContentViewController.h"
@class PageContentViewController;

@interface CLDViewController : UIViewController <UIPageViewControllerDataSource>

@property (weak, nonatomic) IBOutlet UIView *subViewRoot;
- (IBAction)startWalkthrough:(id)sender;
@property (strong, nonatomic) UIPageViewController *pageViewController;
@property (strong, nonatomic) NSArray *pageTitles;
@property (strong, nonatomic) NSArray *pageImages;

@property (strong,nonatomic) PageContentViewController *bounds;
@end

ViewDidLoad 和 RootController 中 UIPageViewController 所需的方法

   - (void)viewDidLoad
 {

    [super viewDidLoad];

    _pageTitles = @[@"Over 200 Tips and Tricks", @"Discover Hidden Features", @"Bookmark Favorite Tip", @"Free Regular Update"];
    _pageImages = @[@"page1.png", @"page2.png", @"page3.png", @"page4.png"];

    // Create page view controller
    self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageViewController"];
    self.pageViewController.dataSource = self;

    PageContentViewController *startingViewController = [self viewControllerAtIndex:0];
    NSArray *viewControllers = @[startingViewController];
    [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

    //Trying to setup the pageViewContoller view to be inside the subview (subViewRoot)
    self.pageViewController.view.frame = self.subViewRoot.bounds;
    [self addChildViewController:_pageViewController];
    [self.subViewRoot addSubview:_pageViewController.view];
    [self.pageViewController didMoveToParentViewController:self];


}


    - (PageContentViewController *)viewControllerAtIndex:(NSUInteger)index
{
    if (([self.pageTitles count] == 0) || (index >= [self.pageTitles count])) {
        return nil;
    }

    // Create a new view controller and pass suitable data.
    PageContentViewController *pageContentViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageContentViewController"];
    pageContentViewController.imageFile = self.pageImages[index];
    pageContentViewController.titleText = self.pageTitles[index];
    pageContentViewController.pageIndex = index;

    return pageContentViewController;
}


- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Page View Controller Data Source



- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController
{
    NSUInteger index = ((PageContentViewController*) viewController).pageIndex;

    if ((index == 0) || (index == NSNotFound)) {
        return nil;
    }

    index--;
    return [self viewControllerAtIndex:index];
}

- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController
{
    NSUInteger index = ((PageContentViewController*) viewController).pageIndex;

    if (index == NSNotFound) {
        return nil;
    }

    index++;
    if (index == [self.pageTitles count]) {
        return nil;
    }
    return [self viewControllerAtIndex:index];
}

- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController
{
    return [self.pageTitles count];
}

- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController
{
    return 0;
}

PageContentViewController.m

-viewDidLoad

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.backgroundImageView.image = [UIImage imageNamed:self.imageFile];
    self.titleLabl.text = self.titleText;

}

有没有人遇到过这种情况？你做了什么？

感谢您的帮助!

最佳答案

由于您将 UIPageViewController 的框架设置为该“ subview ”占位符 View 的框架，因此您需要确保占位符的框架在加载 View 时是准确的.从 xibs 加载的 ViewControllers 通常没有有用的框架，直到它们的 View 被添加到某个地方，它们的 subview 也是如此。 viewWillAppear 通常是最快的，您可以确保您的 viewController 的 View 设置正确。

禁用自动布局会起作用，但是一旦您学会了如何使用自动布局，它就会成为一个不错的功能。在这种情况下，您可以将 subViewRoot 的约束添加到其父 View - Leading、Trailing、Top 和 Bottom。控件从 subViewRoot 拖动到父级是一个简单的快捷方式。

关于ios - 将 UIPageViewController 添加到 subview ， subview 仅显示 pageContentview 的边缘，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25695751/
