ios - 如何在 Eureka 表单上实现滑动 ImageView 作为标题

Question

I am unsure how to implement a sliding imageview like the one in the top of this screenshot.

我正在使用 Eureka 表单，并且我正在尝试将此滑动 ImageView 包含为标题。

目前我正在使用自定义 View ，而这个 Library

我认为问题的根源是由手势识别器和“单击”方法引起的。 Xcode 在 self.presentViewController(ctr,animated: true,completion:nil) 行上抛出错误。我知道它不能在 UIView 中呈现 View Controller 。我只是不确定如何实现在 UIView 子类中呈现 View Controller 的相同结果。

这是我的代码:

class profilePicHeader: UIView {

let slideshow = ImageSlideshow()
var slideshowTransitioningDelegate: ZoomAnimatedTransitioningDelegate?

override init(frame: CGRect) {
    super.init(frame: frame)

    let localSource = [ImageSource(imageString: "GardenExample")!,ImageSource(imageString: "OvenExample")!]


    slideshow.backgroundColor = UIColor.whiteColor()
    slideshow.pageControlPosition = PageControlPosition.UnderScrollView
    slideshow.pageControl.currentPageIndicatorTintColor = UIColor.lightGrayColor();
    slideshow.pageControl.pageIndicatorTintColor = UIColor.blackColor();
    slideshow.contentScaleMode = UIViewContentMode.ScaleAspectFill


    slideshow.setImageInputs(localSource)


    let recognizer = UITapGestureRecognizer(target: self, action: #selector(profilePicHeader.click))
    slideshow.addGestureRecognizer(recognizer)

    slideshow.frame = CGRectMake(0, 0, 320, 200)
    slideshow.autoresizingMask = .FlexibleWidth
    self.frame = CGRectMake(0, 0, 320, 130)
    slideshow.contentMode = .ScaleAspectFit
    self.addSubview(slideshow)
}

func click() {
    let ctr = FullScreenSlideshowViewController()
    ctr.pageSelected = {(page: Int) in
        self.slideshow.setScrollViewPage(page, animated: false)
    }

    ctr.initialImageIndex = slideshow.scrollViewPage
    ctr.inputs = slideshow.images
    slideshowTransitioningDelegate = ZoomAnimatedTransitioningDelegate(slideshowView: slideshow, slideshowController: ctr)
    // Uncomment if you want disable the slide-to-dismiss feature on full screen preview
    // self.transitionDelegate?.slideToDismissEnabled = false
    ctr.transitioningDelegate = slideshowTransitioningDelegate
    self.presentViewController(ctr, animated: true, completion: nil)
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
      }
}

我的解决方案是使用容器 View 和页面 View Controller 。您添加一个容器 View 并设置自动布局约束来调整容器的大小，然后将所有图像添加到内部的页面 View Controller 中。
