導(dǎo)航欄的設(shè)置與處理

*首先創(chuàng)建一個(gè)視圖，并創(chuàng)建好導(dǎo)航欄管理控件

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
       //創(chuàng)建一個(gè)窗口
        self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
        //使窗口可見
        self.window?.makeKeyAndVisible()
        //關(guān)聯(lián)ViewController
        let viewCrt = ViewController()
        //創(chuàng)建導(dǎo)航欄管理器
        let navCrt = UINavigationController(rootViewController: viewCrt)
        self.window?.rootViewController = navCrt
        //設(shè)置導(dǎo)航欄顏色
        navCrt.navigationBar.barTintColor = UIColor.redColor()
        //設(shè)置導(dǎo)航欄上所有添加上去的視圖顏色（包括label和button／image）
        navCrt.navigationBar.tintColor = UIColor.blackColor()
        return true
    }

*然后進(jìn)行添加導(dǎo)航欄上的東西

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        self.view.backgroundColor = UIColor.whiteColor()
        
        //創(chuàng)建一個(gè)系統(tǒng)button
        let button = UIButton(type: .System)
        button.frame = CGRect(x: self.view.frame.size.width / 2 - 50, y: self.view.frame.size.height / 2 - 25, width: 100, height: 50)
        
        button.tintColor = UIColor.redColor()
        button.setTitle("first page", forState: .Normal)
        button.addTarget(self, action: #selector(didClick(_:)), forControlEvents: .TouchUpInside)
        self.view.addSubview(button)
        
        //設(shè)置導(dǎo)航欄上的中間title內(nèi)容，默認(rèn)為居中
        self.navigationItem.title = "首頁(yè)"
        
        //設(shè)置系統(tǒng)的圖標(biāo)擺放至導(dǎo)航欄左側(cè)
//        self.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .Edit, target: self, action: #selector(didClick(_:)))
        self.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "返回", style: .Done, target: self, action: nil)
        
        //設(shè)置導(dǎo)航欄右側(cè)內(nèi)容，添加一個(gè)button，點(diǎn)擊觸發(fā)事件為didClick
        self.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "下一頁(yè)", style: .Plain, target: self, action: #selector(didClick(_:)))
    }
    
    func didClick(sender: UIButton){
        let seconde = secondeViewController()
        //以棧的形式將第二個(gè)頁(yè)面彈出（push）
        self.navigationController?.pushViewController(seconde, animated: true)
    }
    deinit {
        print("first")
    }
}

*觸發(fā)點(diǎn)擊事件，創(chuàng)建第二個(gè)頁(yè)面，第二個(gè)頁(yè)面的代碼如下：

import UIKit

class secondeViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.backgroundColor = UIColor.greenColor()
    }
    //設(shè)置默認(rèn)的返回點(diǎn)擊頁(yè)面（以棧的方式將之前的頁(yè)面返回，pop）
    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        self.navigationController?.popViewControllerAnimated(true)
    }
    
    deinit {
        print("second")
    }
    
}
