本版本的天气预报使用cocoapods添加了第三方代码

具体:

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'

target 'WeatherNew' do
  # Comment this line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for WeatherNew

代码及简单说明

启动:

//
//  AppDelegate.swift
//  WeatherNew
//
//  Created by Input on 16/8/13.

import UIKit
import SwiftyJSON

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        
        let IDPath = NSBundle.mainBundle().pathForResource("weatherId", ofType: "plist")
        let data = NSArray(contentsOfFile: IDPath!)
        
        for i in data!{
            let h = i as! NSDictionary
            WeatherId.weatherId["\(h["weatherName"]!)"] = "w\(h["weatherId"]!)"
        }
        self.window = UIWindow()
        self.window?.frame = UIScreen.mainScreen().bounds
        self.window?.makeKeyAndVisible()
        
        let conTroller = MainView()
        
        let pilot = UINavigationController(rootViewController: conTroller)
        self.window?.rootViewController = pilot
        
        return true
    }
}

此代码用于启动,创建一个导航控制器,MainView(天气界面)作为第一个界面

第一个界面的实现!使用snapkit自动布局实现界面的排版
在self.view上面加载一个collectionView,每一个cell是一个城市的天气

管理界面的实现,就一个tableView,将tableView.tableFooterView设置为添加城市按钮
包括将所添加的城市的信息写入本地文件
