一个iOS项目技术栈分析

1、Podfile文件：

# Uncomment the next line to define a global platform for your project
platform :ios, '11.0'
use_frameworks! :linkage => :static

def common_pods
  pod 'SwifterSwift'
  pod 'SnapKit'
  pod 'IQKeyboardManagerSwift'
end

def network_pods
  pod 'Moya'
  pod 'PromiseKit'
  pod 'PromiseKit/UIKit'
  pod 'Alamofire'
  pod 'PromiseKit/Alamofire'
  pod 'HandyJSON'
end

def ui_pods
  pod 'KDCalendar'
  pod 'FSPagerView'
  pod 'JXSegmentedView', :git => 'https://github.com/pujiaxin33/JXSegmentedView', :branch => 'master'
  pod 'JXPagingView/Paging'
  pod 'Toast-Swift'
  pod 'Kingfisher'
  pod "ESPullToRefresh"
  pod "SideMenu"
end

def other_pods
  pod 'JPush'
  pod 'AMapNavi'
  pod 'AMapLocation'
end


target 'XXX' do
  # Comment the next line if you don't want to use dynamic frameworks

  # Pods for XXX
  common_pods
  ui_pods
  network_pods
  other_pods
end

2、iOS13适配暗黑模式：

if #available(iOS 13.0, *) {
    window?.overrideUserInterfaceStyle = .light;
}

3、判断当前环境：

public var isInProductionMode: Bool {
    // http://stackoverflow.com/questions/9063100/xcode-ios-how-to-determine-whether-code-is-running-in-debug-release-build
    #if DEBUG
        return false
    #else
        return true
    #endif
}

4、Timer tolerance属性：

※这是7.0之后的一个新特性,由于NSTimer不精确,通过它设置误差范围

@property NSTimeInterval tolerance ;

5、判断属性是否是0：

var receivedTime: TimeInterval = 0

if !_orderInfo.receivedTime.isZero {
    sendTimeRows.append(.receive)
}

6、UITableView分类使用枚举：

/// 数据源使用枚举数组，方面后面创建cell之类的使用。
enum Section {
    /// 地址信息
    case address
    /// 配送记录
    case record
    /// 菜品
    case dish
    /// 优惠折扣
    case discount
    /// 总价
    case total
    /// 订单备注/时间
    case info
}

7、线条的高度：

let lineHeight = 1/UIScreen.main.scale

8、闭包定义：

typealias JSONDictionary = [String: Any]

/// 分页返回, next: 是否有下一页
typealias Page<T> = (list:Array<T>,next:Bool,total: Int)

typealias DoubleArray<T,S> = (left:Array<T>,right:Array<S>)

typealias CallBack<T> = (T)->()

使用：

private var phoneCallBack:CallBack<StoreModel>?

页面路由跳转封装：

import UIKit

class Router {
    private let mapVc = RideRoutePlanViewController()
    
    private static let shared = Router()
    
    class func openMap() {
        mainWindow?.rootViewController?.present(shared.mapVc, animated: true, completion: nil)
    }
    
    class func call(phone: String) {
        guard let url = URL(string: "tel://\(phone)") else {
            mainWindow?.show(text: "电话号码有误")
            return
        }
        UIApplication.shared.open(url, options: [:], completionHandler: nil)
    }
}
