Question

在我的iPad应用中。我正在研究UIPageViewController我想在一个页面上设置文本，在另一个页面上设置图像。我已经尝试了很多并用Google搜索，但我找不到任何解决方案。这是在浪费我的时间，所以如果有人参与其中，请指导我并发布示例代码。

我使用了以下链接中的代码

http://www.ioslearner.com/implementing-uipageviewcontroller-programatically-without-storyboarding/

这是示例代码。我使用了contentviewcontroller。

我想使用两个带UIPageViewController的视图控制器

- (UIPageViewControllerSpineLocation)pageViewController:(UIPageViewController *)pageViewController
               spineLocationForInterfaceOrientation:(UIInterfaceOrientation)orientation

{

if(UIInterfaceOrientationIsPortrait(orientation))

{
    //Set the array with only 1 view controller
    UIViewController *currentViewController = [self.pageViewController.viewControllers objectAtIndex:0];
    NSArray *viewControllers = [NSArray arrayWithObject:currentViewController];
    [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];

    //Important- Set the doubleSided property to NO.
    self.pageViewController.doubleSided = NO;
    //Return the spine location
    return UIPageViewControllerSpineLocationMin;

}
else
{
    NSArray *viewControllers = nil;
    ContentViewController *currentViewController = [self.pageViewController.viewControllers objectAtIndex:0];

    NSUInteger currentIndex = [self.modelArray indexOfObject:[(ContentViewController *)currentViewController labelContents]];

     NSUInteger currentIndex2 = [self.imagesArray2 indexOfObject:[(ContentViewController *)currentViewController imageContents]];

    if(currentIndex == 0 || currentIndex %2 == 0 || currentIndex2 == 0||currentIndex2 %2 == 0)
    {
        UIViewController *nextViewController = [self pageViewController:self.pageViewController viewControllerAfterViewController:currentViewController];
        viewControllers = [NSArray arrayWithObjects:currentViewController, nextViewController, nil];
    }
    else
    {
        UIViewController *previousViewController = [self pageViewController:self.pageViewController viewControllerBeforeViewController:currentViewController];
        viewControllers = [NSArray arrayWithObjects:previousViewController, currentViewController, nil];
    }
    //Now, set the viewControllers property of UIPageViewController
    [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];

    return UIPageViewControllerSpineLocationMid;
}

}

Answer 1

如果我理解得很好，那么在ContentPageView.xib文件中添加一个imageView并制作一个插座。将ImageView和标签设置为隐藏或显示在您所需的页面上。

Answer 2

以下步骤可能会有所帮助

在ContentViewController中保留UILabel和UIImageView
在modelArray中添加UIImage或NSString。
当你创建一个新的ContantViewController时，检查模型中的对象是使用以下内容的图像还是字符串。 if ([myObject class] == [UIImage class]) { //HERE ASSIGN IT TO UIIMAGEVIEW.image } else { //HERE ASSIGN IT TO UILABEL.text }

对不起，如果这不是你想要的......
