定位、目的地顯示、路徑規劃、導航

一、首先說說如何接入百度地圖

1)首先打開百度地圖開開放平臺網站，。找到相關下載模塊，根據需求下載所需的SDK包。我這裏選擇的是「所有下載」

2)其次須要在網站上申請密鑰，申請步驟可查看官方文檔。 申請密鑰

3)在工程中接入百度地圖。步驟說明：百度地圖接入

使用CocoaPods。 在當前工程文件（.xcodeproj）所在文件夾下，打開terminal，建立Podfile touch Podfile 編輯Podfile內容以下： pod 'BaiduMapKit' #百度地圖SDK 在Podfile所在的文件夾下輸入命令： pod install （這個可能比較慢，請耐心等待……）

手動配置.framework形式開發包 在工程的3dparty目錄下「New Group」，將所需的包引入 在 TARGETS->Build Phases-> Link Binary With Libaries中點擊「+」按鈕，在彈出的窗口中點擊「Add Other」按鈕，選擇BaiduMapAPI_**.framework添加到工程中。 注意：靜態庫採用objective-c++的形式開發，因此工程中至少要有一個.mm文件，或者修改Project -> Edit Active Target -> Build Setting 中找到 Compile Sources As，並將其設置爲"Objective-C++" 引入所需的系統庫。CoreLocation.framework和QuartzCore.framework、OpenGLES.framework、SystemConfiguration.framework、CoreGraphics.framework、Security.framework、libsqlite3.0.tbd（xcode7之前爲 libsqlite3.0.dylib）、CoreTelephony.framework 、libstdc++.6.0.9.tbd（xcode7之前爲libstdc++.6.0.9.dylib）。在Xcode的Project -> Active Target ->Build Phases ->Link Binary With Libraries，添加這幾個系統庫便可。 若是項目須要基礎地圖功能則需引入mapapi.bundle資源文件。

4）在info.plist中加入 <key>LSApplicationQueriesSchemes</key> <array> <string>baidumap</string> <string>iosamap</string> </array>

二、在所須要的控制器裏面加入地圖顯示用戶當前定位、顯示目標地址（用大頭針標示出來）、路徑規劃導航（百度地圖、高德地圖、系統地圖），詳細說明見代碼註釋
