我目前正在尝试这样做,以便当用户使用我的应用程序时,用户将看到一个动画视图,其中显示,"向左滑动以显示菜单!"我希望一旦用户向左滑动以显示菜单,就不会显示此视图。
以下是一些截图/图表,显示了我的意思:
我已经尝试了一些我在互联网上查找的代码,例如(animView是包含标签的视图,&#34;向左滑动以显示菜单&#34;)但是这个解决方案不起作用:< / p>
if (self.revealViewController().frontViewPosition != FrontViewPosition.left) {
animView.isHidden = true
}
else if (self.revealViewController().frontViewPosition == FrontViewPosition.left){
animView.isHidden = false
}
编辑:我在下面的评论中尝试过提议的解决方案,但是我不确定如何使用它。以下是我的尝试:
func revealController(revealController: SWRevealViewController!, didMoveToPosition position: FrontViewPosition) {
switch(position){
case FrontViewPosition.leftSideMost: break
animView.isHidden = true
default:
break
}
}

仅在第一次显示标签时(第一个问题):
您可以使用SWreveal的didMoveToPosition
方法识别用户刷过菜单。并检查是否revealController.frontViewPosition == FrontViewPositionRight
然后隐藏标签并在SQLite中保存记录,用户已经刷过左侧菜单。并使用ViewDidLoad
或ViewWillAppear
中的SQLite记录检查标签是否需要显示。您可以使用FMDB:github.com/ccgus/fmdb
对于UILabel职位(第二个问题):
它应该是2个子视图(webview是第一个子视图,标签是另一个子视图)。您可以在stackoverflow.com/questions/4631878/
中了解相关信息请记住:
首先 ,不要private
代理无法工作的revealController
函数。还要添加SWRevealViewControllerDelegate
第二次 ,您忘记将self.revealViewController().delegate = self
放入ViewDidAppear
