在我的storyboard
中,我有一个FirstViewController
,它也是一个Initial View Controller
。我的UIViewController
中还有另一个StoryBoard
,名为BaseViewController
。我为此添加了NavigationBar
。我想从FirstViewController
派生BaseViewController
,为此,我编写了以下代码。
class FirstViewController: BaseViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
但是当我运行该应用程序时,它没有显示BaseViewController
的内容。相反,它仅加载FirstViewController
的内容。我希望从UIViewControllere
派生的每个BaseViewController
都应有其NavigationBar
。我需要
改变以得到这个?

如果BaseViewController的目的仅仅是向ViewControllers提供NavigationBar。您可以将FirstViewController(NavController的rootcontroller)嵌入到NavigationController(设置为Initial View Controller)中。 如果要为不同的控制器使用不同的导航栏,则必须像我一样以编程方式进行设置。
在这里看看-
extension UIViewController {
func setNavBar(title : String, modType : ModuleType = .home, barHexColor : String? = nil, isBackBtn : Bool, isMenuBtn : Bool, isJummperBtn : Bool, isScreenshotBtn : Bool) {
k_ModuleType = modType
var barColor = "E14145"
var arrLeftItems = [UIBarButtonItem]()
var arrRightItems = [UIBarButtonItem]()
if let aBarColor = barHexColor {
barColor = aBarColor
}
self.navigationController?.navigationBar.isTranslucent = false
self.navigationController?.navigationBar.barTintColor = UIColor(hexString: barColor)
self.navigationController?.navigationBar.tintColor = UIColor.white
if isBackBtn {
let btnBack = UIButton(type: .custom)
btnBack.setImage(UIImage(named: "Back2"), for: .normal)
btnBack.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
btnBack.addTarget(self, action: #selector(self.barBackAction(_:)), for: .touchUpInside)
let itemBack = UIBarButtonItem(customView: btnBack)
arrLeftItems.append(itemBack)
}
if isMenuBtn {
let btnMenu = UIButton(type: .custom)
btnMenu.setImage(UIImage(named: "menu2"), for: .normal)
btnMenu.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
btnMenu.addTarget(self, action: #selector(self.barMenuAction(_:)), for: .touchUpInside)
let itemMenu = UIBarButtonItem(customView: btnMenu)
arrLeftItems.append(itemMenu)
}
if isScreenshotBtn {
let btnScreenshot = UIButton(type: .custom)
btnScreenshot.setImage(UIImage(named: "screenshot2"), for: .normal)
btnScreenshot.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
btnScreenshot.addTarget(self, action: #selector(self.barScreenshotAction(_:)), for: .touchUpInside)
let itemScreenshot = UIBarButtonItem(customView: btnScreenshot)
arrRightItems.append(itemScreenshot)
}
if isJummperBtn {
let btnJumpper = UIButton(type: .custom)
btnJumpper.setImage(UIImage(named: "jumpper2"), for: .normal)
btnJumpper.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
btnJumpper.addTarget(self, action: #selector(self.barJumpperAction(_:)), for: .touchUpInside)
let itemJumpper = UIBarButtonItem(customView: btnJumpper)
arrRightItems.append(itemJumpper)
}
self.navigationItem.setLeftBarButtonItems(arrLeftItems, animated: true)
self.navigationItem.setRightBarButtonItems(arrRightItems, animated: true)
let lblNavTitle = UILabel(frame: CGRect(x: 0, y: 0,
width: DeviceType.isIPad() ? 200 : 110,
height: 40))
lblNavTitle.textAlignment = .center
lblNavTitle.numberOfLines = 0
lblNavTitle.textColor = UIColor.white
lblNavTitle.text = title
lblNavTitle.font = UIFont.systemFont(ofSize: DeviceType.isIPad() ? 21 : 16,
weight: .medium)
lblNavTitle.backgroundColor = UIColor.clear
self.navigationItem.titleView = lblNavTitle
self.navigationItem.titleView?.isUserInteractionEnabled = true
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.tapTitle(_:)))
tapGesture.numberOfTapsRequired = 1
self.navigationItem.titleView?.addGestureRecognizer(tapGesture)
}
然后使用FirstViewController的Viewdidload()方法
override func viewdidload()
{
super.viewdidload()
self.setNavBar(title : aTitle,
barHexColor : nil,
isBackBtn : false,
isMenuBtn : true,
isJummperBtn : true,
isScreenshotBtn : true)
}
