NavigationBar Jumping Problem
Hi guys, first of all, thanks for creating such a great UI library. I enjoy using this framework.
Recently, I saw a problem about when navigation back through the back button. The navigation bar is jumping when back button pressed. My code is not customized, it s from sample project. Can you help me to solve jumping?
Main NavigationController code is below;
class AppNavigationController: NavigationController { open override func prepare() { super.prepare() isMotionEnabled = true guard let v = navigationBar as? NavigationBar else { return }
v.backgroundColor = .white
v.depthPreset = .none
v.dividerColor = Color.grey.lighten2
}
override var preferredStatusBarStyle: UIStatusBarStyle{
if #available(iOS 13.0, *) {
return .darkContent
} else {
return .default
}
}
}
These are the root ListViewController UI lifecycle functions. Nothing is special.
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
}
Take a screenshot of your screen using the "Debug View Hierarchy", try to use certain angle to see how is render the logo used as avatar on your navitgationBar.
Same, here's a quick fix though be alerted that it MAY CORRUPT your other views, because I haven't checked other components of this library, but here it is. Remove these lines of code from the library
// iOS 11 added left/right layout margin in subviews of UINavigationBar
// since we do not want to unsafely access private views directly, we
// iterate through the subviews to set `layoutMargins` to zero
for v in subviews {
if #available(iOS 13.0, *) {
let margins = v.layoutMargins
v.frame.origin.x = -margins.left
v.frame.size.width += margins.left + margins.right
} else {
v.layoutMargins = .zero
}
}
Though, I'd like it to be solved by the creators of the library
