Use of the iOS Baidu map

Here is not the specific configuration of the introduction of Baidu, configuration see HTTP://DEVELOPER.BAIDU.COM/MAP/INDEX.PHP?TITLE=IOSSDK

1. First accept the basic map function

Create a new map class, xib drag also line, my side is the code implementation.

 _mapview = [[bmkmapview alloc]initwithframe:cgrectmake (0, 0, Self.view.frame.size.width, self.view.frame.size.height)]; [self.view addsubview:_mapview];# pragma mark -  Setting Mapview Property-(void) Setmapviewproperty{    _mapview.maptype  = bmkusertrackingmodefollowwithheading;    _mapview.showsuserlocation =  yes;    _mapview.zoomlevel = 16;    _ mapview.rotateenabled = no;        [self   Passlocationvalue];} #pragma  mark -incoming location coordinates   (you must have obtained geolocation coordinates when you open the program, always show Tiananmen first in order to resolve map positioning)-(void) passlocationvalue{     bmkcoordinateregion viewregion = bmkcoordinateregionmake ([UserLocationManager  sharedinstance].clloction.coordinate, bmkcoordinatespanmake (0.02f,0.02f));     Bmkcoordinateregion adjustedregion = [_mapview regionthatfits:viewregion];    [_mapview setregion:adjustedregion  animated:yes];    } #pragma  mark -set the Anchor dot Property-(void) setuserimage{     bmklocationviewdisplayparam* param = [[bmklocationviewdisplayparam alloc] init] ;    param.locationviewoffsety = 0;     param.locationviewoffsetx = 0;    param.isaccuracycircleshow =no;     param.isRotateAngleValid = NO;    [_mapView  Updatelocationviewwithparam:param];}

To implement Bmkmapviewdelegate, here are some protocol methods for Mapview

* * This interface will be called when the map area is about to change * @param mapview map View * @param animated whether the animation */-(void) Mapview: (Bmkmapview *) Mapview Regionwillchange Animated: (BOOL) animated{//todo}/** * This interface will be called when the map area is changed * @param mapview map View * @param animated whether animation */-(void) Mapview: (BMK Mapview *) Mapview regiondidchangeanimated: (BOOL) animated{//todo}/** * This interface will be called after the map state change is complete * @param mapview map view */-(void) Mapstatusdidchanged: (Bmkmapview *) mapview{//todo}

So the basic map interface is out.

2. Map positioning

I'm on my side. Encapsulates a standalone manager class to manage positioning and slide-to-position on the map

#import   "UserLocationManager.h" #import   "BMKGeocodeSearch.h" @implementation  userlocationmanager+   (userlocationmanager *) sharedinstance{    static userlocationmanager  *_instance = nil;         @synchronized   (self)  {         if  (_instance == nil)  {             _instance = [[self alloc] init];         }    }         return _instance;} -(ID) init{    if  (self == [super init])     {         //[self getBMKUserLocation];         //[self initgeocodesearch];    }     return self;} #pragma   Initialize Baidu map user Location management class/** *   initialize Baidu Map user location management  */-  (void) initbmkuserlocation; {    _locservice = [[bmklocationservice alloc]init];     _locservice.delegate = self;    [self startlocation];} #pragma   Open Location Services/** *   Open Location Services  */-(void) startlocation{    [_ Locservice startuserlocationservice];} #pragma   Close Location Services/** *   turn off location services  */-(void) stoplocation{    [_ Locservice stopuserlocationservice];} This function is called when the  bmklocationservicedelegate/** * user location update is #pragma  * @param  userLocation  New User Location  */-  (void) Didupdateuserlocation: (bmkuserlocation *) userlocation{      cllocation = userlocation.location;    _clloction = cllocation;     _userlatitude = cllocation.coordinate.latitude;    _userlongitude = cllocation.coordinate.longitude;     [self stoplocation];    [self initgeocodesearch];} /** * This function is called when the location is stopped  */-  (void) didstoplocatinguser{    [_mapviewvc  Setmapviewproperty];} This function is called when the/** * location fails  * @param  error  error number  */-  (void) Didfailtolocateuserwitherror: ( nserror *) error{    [self stoplocation];} #pragma  bmkgeocodesearchdelegate-(void) initgeocodesearch{    _geocodesearch =  [[BMKGeoCodeSearch alloc]init];    _geoCodeSearch.delegate = self;     bmkreversegeocodeoption *reversegeocodeoption= [[bmkreversegeocodeoption  alloc] init];    reverseGeoCodeOption.reverseGeoPoint =  Cllocation.coordinate;    [_geocodesearch reversegeocode:Reversegeocodeoption];} /** * returns the anti-geocoding search results  * @param  searcher  Search Object  * @param  result  search Results  * @param  error  error number, @see  bmksearcherrorcode */-(void)  ongetreversegeocoderesult: ( bmkgeocodesearch *) Searcher result: (bmkreversegeocoderesult *) Result errorcode: ( Bmksearcherrorcode) error{    if  (error == 0)     {         _cityName = result.addressDetail.city;         nslog (@ "%@", _cityname);     }} @end
