ios - 如何在没有手势的情况下自动触发翻页转换？

Question

我使用带有 PageControl 的 UIPageViewController 在我的 PageViewController 中显示图像。一切都很完美。但是页面是否有可能在特定时间后自动滑动(滚动)到下一页？

你有这段代码但不起作用，我需要 UIPageViewController 自动滚动。

NSTimer *aTimer;
NSArray *viewControllers;


-(void)viewDidAppear:(BOOL)animated{

    aTimer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(animacion) userInfo:nil repeats:YES];

}


-(void)animation{

[pageVCObj setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:nil];
} 



- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.


    self.pageController.doubleSided =YES;

    self.pageController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStylePageCurl navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];

    self.pageController.dataSource = self;
    [[self.pageController view] setFrame:[[self view] bounds]];

    APPChildViewController5 *initialViewController = [self viewControllerAtIndex:0];

     viewControllers = [NSArray arrayWithObject:initialViewController];

    [self.pageController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

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


}

你有一个错字:

aTimer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(animacion) userInfo:nil repeats:YES];

您提供选择器名称 animacion 但您的方法称为 animation。
