如何在 UIPageViewController 中以全尺寸显示图像？

Question

我目前正在欢迎屏幕中工作。
为此，我使用了 UiPageViewController。
我从 appcode 下载了演示
链接是：UIPageViewController

但是当我下载演示图像时显示是这样的。

我的要求是我想以全尺寸显示图像 请帮帮我怎么办

Answer 1

在该代码上更改高度，例如

 // Change the size of page view controller
self.pageViewController.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height + 30 ); it is by default -30 change to any one of + 30 or else

你得到的输出为

更新答案

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
 // Override point for customization after application launch.
 //    UIPageControl *pageControl = [UIPageControl appearance];
//    pageControl.pageIndicatorTintColor = [UIColor lightGrayColor];
//    pageControl.currentPageIndicatorTintColor = [UIColor blackColor];
//    pageControl.backgroundColor = [UIColor clearColor];

return YES;
}

否则只需更改pageControl.currentPageIndicatorTintColor = [UIColor blackColor]; clearColor

第一步

// hide your PageControl in Appdelegate 

  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
 // Override point for customization after application launch.
 //    UIPageControl *pageControl = [UIPageControl appearance];
//    pageControl.pageIndicatorTintColor = [UIColor lightGrayColor];
//    pageControl.currentPageIndicatorTintColor = [UIColor blackColor];
//    pageControl.backgroundColor = [UIColor clearColor];

return YES;
}

第二步

在你的 pageController 声明 View Controller 上做喜欢

@interface SurveyViewController (){
UIPageControl *pagecontrol;
NSInteger currentIndex;
}

- (void)viewDidLoad {
currentIndex = 0;
 [self setupPageControl];
}

- (void)setupPageControl{
pagecontrol = [UIPageControl  appearance];
pagecontrol.pageIndicatorTintColor = [UIColor lightGrayColor];
pagecontrol.currentPageIndicatorTintColor = APPBGCOLOR;
pagecontrol.backgroundColor = [UIColor clearColor];
[self.view bringSubviewToFront:pageControl];


}


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


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

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

index--;
 currentIndex = index;
[self.pageControl setCurrentPage: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;
}
 currentIndex = index;
  [self.pageControl setCurrentPage:index];
return [self viewControllerAtIndex:index];
}
