添加多个航点时出现Google Maps Directions url错误 [英] Google Maps Directions url error when adding multiple waypoints
本文介绍了添加多个航点时出现Google Maps Directions url错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试将多个航点添加到我的Google方向请求中。
当我添加一个像
https：//maps.googleapis的.com /地图/ API /方向/ JSON&安培;原点= 51.507679，-0.125004&安培;航点= 51.524151，-0.123174&安培;目的地= 51.495777，-0.108642&安培;模式=步行
它可以正常工作，但当我尝试添加多个航点时，例如
https： //maps.googleapis.com/maps/api/directions/json?&origin=51.606502,0.527309&waypoints=51.507679,-0.125004|51.524151,-0.123174&destination=51.495777,-0.108642&mode=walking
我收到了'不受支持的网址'错误。什么是添加多个航点的正确方法？谢谢

I am trying to add multiple waypoints to my google directions request.
When I add a single waypoint like
https://maps.googleapis.com/maps/api/directions/json?&origin=51.507679,-0.125004&waypoints=51.524151,-0.123174&destination=51.495777,-0.108642&mode=walking
it works fine but when I try to add multiple waypoints like
https://maps.googleapis.com/maps/api/directions/json?&origin=51.606502,0.527309&waypoints=51.507679,-0.125004|51.524151,-0.123174&destination=51.495777,-0.108642&mode=walking
i receive a 'unsupported URL' error. What is the correct way to add multiple waypoints? Thanks
解决方案
I give you the solution step by step
First we should get the Google Map SDK
Drag the following bundles into your project (when prompted, select Copy items if needed):
Subspecs/Base/Frameworks/GoogleMapsBase.framework
Subspecs/Maps/Frameworks/GoogleMaps.framework
Subspecs/Maps/Frameworks/GoogleMapsCore.framework
Right-click GoogleMaps.framework in your project, and select Show In Finder.
Drag the GoogleMaps.bundle from the Resources folder into your project. When prompted, ensure Copy items into destination group's folder is not selected.
Select your project from the Project Navigator, and choose your application's target.
Open the Build Phases tab, and within Link Binary with Libraries, add the following frameworks:
GoogleMapsBase.framework
GoogleMaps.framework
GoogleMapsCore.framework
GoogleMapsM4B.framework (Premium Plan customers only)
Accelerate.framework
CoreData.framework
CoreGraphics.framework
CoreLocation.framework
CoreText.framework
GLKit.framework
ImageIO.framework
libc++.tbd
libz.tbd
OpenGLES.framework
QuartzCore.framework
SystemConfiguration.framework
UIKit.framework
Now Get the API key
Now you need to add following things in Plist
AppDelegate.m
@import GoogleMaps;

[GMSServices provideAPIKey:@"YOUR API KEY"];
