1. First, how to access Baidu Map

1) Open Baidu Map and Open Platform Website first. Find the relevant download module and download the SDK packages as required. I chose "Download All" here.

2) Next, it is necessary to apply for the key on the website, and the application procedure can see the official documents. Application key

3) Access Baidu Map in the project. Statement of steps: Baidu Map Access

Use Cocoa Pods. In the folder where the current project file (. xcodeproj) is located, open terminal and create Podfile touch Podfile Edit Podfile as follows: Pod'Baidu Map Kit'#Baidu Map SDK Enter the command in the folder where Podfile is located: pod install (this may be slower, please wait patiently...)

Manual configuration. framework form development kit Introduce the required packages under "New Group" in the 3D part directory of the project Click the "+" button in TARGETS - > Build Phases - > Link Binary With Libaries, click the "Add Other" button in the pop-up window, and select Baidu Map API **. framework to add to the project. Note: Static libraries are developed in the form of objective-c++, so there should be at least one. mm file in the project, or modify Project-> Edit Active Target-> Build Setting to find Compile Sources As and set it to "Objective-C++". Introduce the required system library. CoreLocation.framework and Quartz Core. framework, OpenGLES.framework, System Configuration. framework, CoreGraphics.framework, Security.framework, libsqlite3.0.tbd (libsqlite3.0.dylib before Xcode 7), CoreTelephony.framework, libstdc+.6.0.9.tbd (libstdc+.6.0.9.dylib before Xcode 7). In Xcode Projects - > Active Target - > Build Phases - > Link Binary With Libraries, add these system libraries. If the project needs the basic map function, the mapapi.bundle resource file needs to be introduced.

4) Add in info.plist <key>LSApplicationQueriesSchemes</key> <array> <string>baidumap</string> <string>iosamap</string> </array>

2. Add maps to the required controllers to display the user's current location, display the target address (marked with a pin), path planning and navigation (Baidu Map, Gaode Map, Systematic Map). See Code Notes for details.
