iOS Map Integration example: Baidu Map poi Search

First, integrated Baidu map (fool tutorial, to the site description document, here are listed a few major steps)

1, Login http://lbsyun.baidu.com Baidu Map developer platform, access to the SDK and integration documentation.

2, Baidu Map can provide some of the services

(1) Map: Provide map display and map operation function;

(2) POI search: Support peripheral Search, regional search and intra-city point of interest retrieval;

(3) Geocoding: Provide the interface between latitude and longitude and the conversion of address information;

(4) Line planning: Support bus, driving, walking, riding, four ways of route planning;

(5) Overlay layer: Support to add overlay on the map (callout, geometry, heat force diagram, topographic map layer, etc.), to display more abundant lbs information;

(6) Positioning: Get the current position information and display on the map (support normal, follow, compass three modes);

(7) Offline Map: Use offline map to save user traffic and provide better map display effect;

(8) Switch Baidu Map: Using the SDK interface, directly on the local Baidu map client or WebApp, to achieve map function;

(9) Peripheral radar: The use of peripheral radar function, developers can be in the app low-cost, fast to find the surrounding use the same app user location function;

LBS Cloud Search: Support to query the data stored in the LBS cloud;

(11) Tile layer: Support to add own tile data on the map.

(12) Featured features: Provide short-string sharing, place details search, hot force and other features to help developers build more powerful applications;

2, create the application, get Appkey (key)

(1) You need to get key as a developer

(2) Note binding to bundle identifier

3. Precautions before configuring integration

(1) Strict reference documents!

(2) Several points of attention

<1> iOS9.0, to configure ATS in Info.plist

<2> in Info.plist Configure the whitelist of Baidu maps application (support to open Baidu map in its own application)

<3> Manage the life cycle of the map (manually empty the proxy)

<4> Add a reminder to get a location authorization in Info.plist

nslocationwheninuseusagedescription, allowing the GPS description to be used in the foreground

nslocationalwaysusagedescription, allow permanent use of GPS description

4. Configure the development environment

(1) Add Baidu's static library (. Framework)

(2) Import a large stack of system libraries

(3) Add Map package (Mapapi.bundle resource file)

(4) Introduction of all Header files

5. Initialize the map

(1) Initialize Bmkmapmanager

(2) Create Bmkmapview

6. Basic Map

(1) See the documentation! Http://lbsyun.baidu.com/index.php?title=iossdk/guide/basicmap

(2) Understanding of some functions

<1> map types: Normal vector maps, satellite maps, and blank maps (save traffic)

<2> Open a live traffic layer

<3> Thermal Map

<4> gestures, map controls, subscripts, polylines (shading of geometry)

<5> Set the map display range

<6>, etc...
