swift中UINavigationController的使用

概述// 导航视图控制器标题self.navigationItem.title = "navigationController" // 导航视图控制器样式self.navigationController!.setNavigationStyleDefault() // 导航视图控制器左按钮self.navigationItem.leftBarButtonIte

// 导航视图控制器标题self.navigationItem.Title = "navigationController"        // 导航视图控制器样式self.navigationController!.setNavigationStyleDefault()        // 导航视图控制器左按钮self.navigationItem.leftbarbuttonItem = UIbarbuttonItem(Title: "present",style: UIbarbuttonItemStyle.Done,target: self,action: Selector("presentClick"))self.navigationItem.leftbarbuttonItem!.tintcolor = UIcolor.greencolor()        // 导航视图控制器右按钮self.navigationItem.rightbarbuttonItem = UIbarbuttonItem(Title: "push",action: Selector("pushClick"))self.navigationItem.rightbarbuttonItem!.tintcolor = UIcolor.orangecolor()

// 注意：如果下个视图控制器的导航栏样式与当前的不一样时，返回当前视图控制器时，需要重置下样式overrIDe func vIEwWillAppear(animated: Bool) {        super.vIEwWillAppear(animated)                // 导航视图控制器样式        self.navigationController!.setNavigationStyleDefault()}

// 导航视图控制器样式self.navigationController!.setNavigationStyle(UIcolor.orangecolor(),textFont: UIFont.boldSystemFontOfSize(12.0),textcolor: UIcolor.yellowcolor())

// 导航栏隐藏，或显示let button = UIbutton(frame: CGRectMake(10.0,10.0,(CGRectGetWIDth(self.vIEw.frame) - 10.0 * 2),40.0))self.vIEw.addSubvIEw(button)button.backgroundcolor = UIcolor.lightGraycolor()button.setTitle("隐藏导航栏",forState: UIControlState.normal)button.setTitlecolor(UIcolor.blackcolor(),forState: UIControlState.normal)button.setTitlecolor(UIcolor.redcolor(),forState: UIControlState.Highlighted)button.addTarget(self,action: Selector("hIDdenClick:"),forControlEvents: UIControlEvents.touchUpInsIDe)button.selected = false
