使用按钮执行入职页面

Perform Onboarding Pager with a boutton

我正在使用现有项目(https://github.com/ThornTechPublic/Onboarding-With-UIPageViewController-Final ) . I want to perform the slide with a boutton also. I want my button "Next" to do the same functionality as swiping so when the user taps it, it moves to the next screen. Button in blue。如何操作?提前致谢。

我是这样做的:我在页面上使用 NSNotification,它让 OnboardingPager 知道按钮何时被按下,并执行适当的操作。

举个例子:在 StepZero 页面中,我做了以下操作

@IBAction func nextPressed(sender: UIButton) {
    NSNotificationCenter.defaultCenter().postNotificationName("testbutton", object: nil)
}

然后在 OnboardingPager class 中,我添加了以下内容

override func viewDidLoad() {
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(nextPage(_:)), name: "testbutton", object: nil)
}

func nextPage(notification:NSNotification) {
    self.setViewControllers([getStepOne()],
             direction: UIPageViewControllerNavigationDirection.Forward,
             animated: true,
             completion: nil)
}

这样您就可以从第一页 (StepZero) 转到第二页 (StepOne)。
