我在Euro Sport中制作应用程序。我的rootviewController是pageViewController,它有3个VC。向左和向右滑动即可更改VC。接下来,我添加了sidebarmenu。我想在整个rootViewController中添加手势识别器。这是我添加手势的方式:
self.exitPanGesture = UIPanGestureRecognizer()
self.exitPanGesture.addTarget(self, action:"handleOffstagePan:")
self.sourceViewController.view.addGestureRecognizer(self.exitPanGesture)
self.sourceViewController.navigationController?.view.addGestureRecognizer(self.exitPanGesture)
当我拖动rootviewController轻击导航栏时,它可以工作。但是像segmentcontrol和pageContent这样的其他部分也不起作用。
我在这里设置sourceViewController:
func resetToMainPage(index: Int!) {
/* Getting the page View controller */
mainPageViewController = self.storyboard?.instantiateViewControllerWithIdentifier("MainPageViewController") as UIPageViewController
self.mainPageViewController.dataSource = self
self.mainPageViewController.delegate = self
pageContentViewController = self.viewControllerAtIndex(index)
// self.transtionManger.sourceViewController = pageContentViewController // adding swipe to the pageContentViewControlle in order to close menu
self.transtionManger.sourceViewController = mainPageViewController
self.mainPageViewController.setViewControllers([pageContentViewController!], direction: UIPageViewControllerNavigationDirection.Forward, animated: true, completion: nil)
self.mainPageViewController.view.frame = CGRectMake(0, 102, self.view.frame.width, self.view.frame.height)
self.addChildViewController(mainPageViewController)
self.view.addSubview(mainPageViewController.view)
self.mainPageViewController.didMoveToParentViewController(self)
}
所以,我的问题是如何在整个rootViewController中添加手势识别器,包括navbar,segmentcontrol,pageviewcontrol?

手势识别器只能附加到一个视图。因此,下面的行表示只有navigationController?.view
才会添加手势。
self.sourceViewController.view.addGestureRecognizer(self.exitPanGesture)
self.sourceViewController.navigationController?.view.addGestureRecognizer(self.exitPanGesture)
您可以为要打开的每个视图复制手势识别器,然后以这种方式添加它们。
self.exitPanGesture1 = UIPanGestureRecognizer()
self.exitPanGesture1.addTarget(self, action:"handleOffstagePan:")
self.sourceViewController.view.addGestureRecognizer(self.exitPanGesture1)
self.exitPanGesture2 = UIPanGestureRecognizer()
self.exitPanGesture2.addTarget(self, action:"handleOffstagePan:")
self.sourceViewController.navigationController?.view.addGestureRecognizer(self.exitPanGesture2)

我还没试过这个,但在SO UITapGestureRecognizer tap on self.view but ignore subviews
上发现了类似的问题这可能会帮助您找到解决方案。

extension UIView {
public func removeAllConstraints() {
var _superview = self.superview
while let superview = _superview {
for constraint in superview.constraints {
if let first = constraint.firstItem as? UIView, first == self {
superview.removeConstraint(constraint)
}
if let second = constraint.secondItem as? UIView, second == self {
superview.removeConstraint(constraint)
}
}
_superview = superview.superview
}
self.removeConstraints(self.constraints)
self.translatesAutoresizingMaskIntoConstraints = true
}
}
出于某种原因,navBar.view上的识别器无法正常工作。如果我以这种方式编写代码:
for singleView in self.sourceViewController.view.subviews {
singleView.addGestureRecognizer(exitPanGesture)
singleView.navigationController??.view.addGestureRecognizer(exitPanGesture)
}
只有导航栏手势工作,子视图手势不起作用。如果我改变了这段代码的顺序。导航栏手势不起作用,但子视图手势工作。如何向两个视图添加手势?
