[英]NavigationItem titleView is coming at left side for some time then move to Center
我正在將自定義視圖設置為導航的titleView。 當viewcontroller出現時,它的標題視圖會在左側出現一段時間然后移動到中心,這可能是錯的? 我使用以下代碼
let itemImgs: [UIImage] = [UIImage(named: "MORE_Location")!, UIImage(named: "MORE_Department")!, UIImage(named: "By_Teams")!, UIImage(named: "MORE_Status")!]
self.navigationController?.navigationBar.isTranslucent = false
self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
menuView = BTNavigationDropdownMenu(navigationController: self.navigationController, containerView: self.navigationController!.view, title: AppMessage.EDEmployeePeople, items: items as [AnyObject], itemImgs: itemImgs)
menuView.cellHeight = 60
menuView.cellBackgroundColor = UIColor.red
menuView.cellSelectionColor = UIColor.clear
menuView.cellSeparatorColor = UIColor.clear
menuView.shouldKeepSelectedCellColor = false
menuView.cellTextLabelColor = UIColor.white
menuView.shouldChangeTitleText = false
menuView.cellTextLabelFont = UIFont(name: "Helvetica", size: 17)
if appNeedsAutoResize
{
menuView.cellTextLabelFont = UIUtils.getFontForApproprieteField(.subHeadline).font
}
menuView.cellTextLabelAlignment = .left // .Center // .Right // .Left
menuView.arrowPadding = 15
menuView.animationDuration = 0.5
menuView.maskBackgroundColor = UIColor.clear
menuView.maskBackgroundOpacity = 0.3
menuView.didSelectItemAtIndexHandler = {(indexPath: Int) -> () in
print("Did select item at index: \(indexPath)")
if indexPath == 3
{
let byStatusViewController = ByStatusViewController(nibName: "ByStatusViewController", bundle: nil)
//UIUtils.pushViewWhenHideBottom(self, anotherVC: byStatusViewController)
self.navigationController?.pushViewController(byStatusViewController, animated: true)
}
else
{
let dropVC = DepartmentViewController(nibName: "DepartmentViewController", bundle: nil)
switch indexPath
{
case 0:
dropVC.employeeGroupInfo = EmployeeGroupInfo.locationInfo
break
case 1:
dropVC.employeeGroupInfo = EmployeeGroupInfo.departmentInfo
break
default:
dropVC.employeeGroupInfo = EmployeeGroupInfo.teamInfo
break
}
// UIUtils.pushViewWhenHideBottom(self, anotherVC: dropVC)
self.navigationController?.pushViewController(dropVC, animated: true)
}
}
self.navigationItem.titleView = menuView
}
嘗試將自動調整遮罩的約束添加到菜單視圖以使視圖居中。
例如
menuView.autoresizingMask = [.flexibleLeftMargin, .flexibleRightMargin, .flexibleTopMargin, .flexibleBottomMargin]
我有這個問題,並改變我的功能,自定義我的navigationItem從viewWillAppear()
到viewDidLoad()
