如何移除 iOS 中的 UIPageViewController 弹跳效果 for Swift 3/4
How to remove UIPageViewController's Bounce effect in iOS for Swift 3/4
这是我的问题的截图:
我已经按照下面的代码完成了。
func scrollViewDidScroll(scrollView: UIScrollView) {
if currentIndex == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width {
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)
} else if currentIndex == totalViewControllers - 1 && scrollView.contentOffset.x > scrollView.bounds.size.width {
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)
}
}
func scrollViewWillEndDragging(scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
if currentIndex == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width {
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)
} else if currentIndex == totalViewControllers - 1 && scrollView.contentOffset.x > scrollView.bounds.size.width {
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)
}
}
首先在你的 UIPageViewController 中找到 scrollview 并添加 UIScrollViewDelegate
for view in self.pageViewController!.view.subviews {
if let subView = view as? UIScrollView {
subView.delegate = self
subView.isScrollEnabled = true
subView.bouncesZoom = false
}
}
(在您的 ViewController class 中扩展 UIScrollViewDelegate)
对于方法 "scrollViewDidScroll" 和 "scrollViewWillEndDragging" 上的 UIScrollViewDelegate,您可以添加如下内容
func scrollViewDidScroll(_ scrollView: UIScrollView) {
if(currentIndex == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width){
scrollView.contentOffset = CGPoint(x:scrollView.bounds.size.width, y:0.0)
}else if(currentIndex == 2 && scrollView.contentOffset.x > scrollView.bounds.size.width) {
scrollView.contentOffset = CGPoint(x:scrollView.bounds.size.width, y:0.0)
}
}
func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
if(currentIndex == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width){
scrollView.contentOffset = CGPoint(x:scrollView.bounds.size.width, y:0.0)
}else if(currentIndex == 2 && scrollView.contentOffset.x > scrollView.bounds.size.width) {
scrollView.contentOffset = CGPoint(x:scrollView.bounds.size.width, y:0.0)
}
}
