推荐答案
您可以在动画中更改标签栏的框架,例如:
You could change the tab bar's frame inside an animation, so something like:
func hideTabBar() {
var frame = self.tabBarController?.tabBar.frame
frame?.origin.y = self.view.frame.size.height + (frame?.size.height)!
UIView.animate(withDuration: 0.5, animations: {
self.tabBarController?.tabBar.frame = frame!
})
}
func showTabBar() {
var frame = self.tabBarController?.tabBar.frame
frame?.origin.y = self.view.frame.size.height - (frame?.size.height)!
UIView.animate(withDuration: 0.5, animations: {
self.tabBarController?.tabBar.frame = frame!
})
}
将标签栏设置在可见屏幕的正下方,以便它从底部向上/向下滑动.
Which sets the tab bar just below the visible screen, so that it slides up/down from the bottom.
