UINavigationItem基础
//导航条 -> 属性导航控制器
//navigationItem -> 让导航控制器管理的视图控制器
//创建window
self.window = UIWindow.init(frame: UIScreen.mainScreen().bounds)
self.window?.backgroundColor = UIColor.whiteColor()
let navC = YTNavigationController(rootViewController: OneViewController())
self.window?.rootViewController = navC
//将状态栏变成白色(默认是黑色)
//1.在info.plist文件中去添加一个键值对 -> View controller-based status bar appearance:NO
//2.通过应用程序对象改变状态栏的样式
//a.拿到当前应用程序对象
let app = UIApplication.sharedApplication()
//b.设置状态栏的样式
//LightContent -> 白色
app.statusBarStyle = .LightContent
//定制导航条
//1.设置背景颜色
self.navigationBar.barTintColor = UIColor.blackColor()
//2.设置填充颜色
self.navigationBar.tintColor = UIColor.whiteColor()
func navigationItemSetting() {
//1.定制rightItem
//a.通过其他视图来创建一个UIBarButtonItem对象
let btn = UIButton.init(frame: CGRectMake(0, 0, 50, 30))
btn.setTitle("注册", forState: .Normal)
btn.setBackgroundImage(UIImage.init(named: "buttonbar_action.png"), forState: .Normal)
btn.setTitleColor(UIColor.greenColor(), forState: .Normal)
btn.addTarget(self, action: "btnAction", forControlEvents: .TouchDown)
let item1 = UIBarButtonItem.init(customView: btn)
//b.通过一张图片创建一个UIBarButtonItem对象
//参数1:图片
//参数2:item的风格
//参数3:调用方法的对象
//参数4:当当前item对应的按钮被点击后会调用的方法
let item2 = UIBarButtonItem.init(image: UIImage.init(named: "itemImage")?.imageWithRenderingMode(.AlwaysOriginal), style: .Plain, target: self, action: "itemAction:")
//c.通过文字去创建一个UIBarButtonItem对象
let item3 = UIBarButtonItem.init(title: "注册", style: .Plain, target: self, action: "itemAction:")
//d.通过系统样式去创建UIBarButtonItem对象
//参数1:指定的系统样式
let item4 = UIBarButtonItem.init(barButtonSystemItem: .Add, target: self, action: "itemAction:")
//2.设置navigationBar右边的显示
//a.在右边显示一个视图
self.navigationItem.rightBarButtonItem = item4
//b.在右边显示显示多个视图
//self.navigationItem.rightBarButtonItems = [item4,item3]
//3.设置navigationBar左边的显示
self.navigationItem.leftBarButtonItem = item2
//self.navigationItem.leftBarButtonItems = [item1, item2]
//4.设置navigationBar中间的显示
//a.显示纯文字
self.title = "登录"
//b.通过一个label显示文字
let label = UILabel.init(frame: CGRectMake(0, 0, 100, 30))
label.text = "登录"
label.textColor = UIColor.yellowColor()
label.textAlignment = .Center
//c.创建中间显示的分段选中器
let segement = UISegmentedControl.init(items: ["海贼","火影"])
segement.frame = CGRectMake(0, 0, 100, 40)
segement.selectedSegmentIndex = 0
//设置中间视图
self.navigationItem.titleView = segement
//设置背景颜色
self.view.backgroundColor = UIColor.orangeColor()
//设置rightItem
let item = UIBarButtonItem.init(barButtonSystemItem: .Cancel, target: self, action: "itemAction")
self.navigationItem.rightBarButtonItem = item
//1.替换系统自带的返回按钮 -> 设置leftBarButtonItem属性
let item2 = UIBarButtonItem.init(barButtonSystemItem: .Done, target: self, action: "itemAction")
//self.navigationItem.leftBarButtonItem = item2
//2.隐藏系统自带的返回按钮
self.navigationItem.hidesBackButton = true
toolBar

//1.定制toolBar(高度是44)
//toolBar属于导航控制器，默认是隐藏的
//a.让toolBar显示出来
self.toolbarHidden = false

//2.定制导航条
//a.设置背景颜色
self.navigationBar.barTintColor = UIColor.blackColor()
