Build Baidu maps, walking routes, anti-geocoding applications

-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (nsdictionary *) launchOptions

    {

    //Start engine baidumapmanager

    _mapmanager = [[Bmkmapmanager alloc]init];

    If you want to focus on network and authorization authentication events, set the Generaldelegate parameter, otherwise nil can

    BOOL ret = [_mapmanager start:@ "Valid key for the application" Generaldelegate: (id< bmkgeneraldelegate>) self];

    if (!ret) {

    NSLog (@ "manager start failed!");

    }

    Self.window = [[[UIWindow alloc] initwithframe:[[uiscreen mainscreen] bounds]] autorelease];

    Override point for customization after application launch.

    Self.viewcontroller = [[[Viewcontroller alloc] initwithnibname:@ "Viewcontroller" Bundle:nil] autorelease];

    Self.window.rootViewController = Self.viewcontroller;

    [Self.window makekeyandvisible];

    return YES;

    }

Create a map with xib or manually

In-(void) Viewwillappear: (BOOL) animated to set the proxy (or create a setting when viewdidload), remember, otherwise the grid may appear without the map.

_mymapview=[[bmkmapview Alloc] Initwithframe:cgrectmake (0, 0, Screen.width, screen.height)];

    [Super viewwillappear:animated];
    [_mapview viewwillappear];
    _mapview.showsuserlocation = no;//First turns off the displayed positioning layer
    _mapview.usertrackingmode = bmkusertrackingmodenone;//Sets the status of the positioning
    _mapview.showsuserlocation = yes;//display positioning layer
      _mapview.delegate = self;
    _geocodesearch.delegate = self;
    _userlocation.delegate = self;
    _walkingrouteplanoption.delegate = self;

Walking route agent, positioning agent and so on.

When you exit the interface (note. cannot be in the Viewwilldisappear method, as for why listen to others said Baidu Map and iOS conflict) set the agent to empty

        [_mapview viewwilldisappear];
        _mapview.delegate = nil;
        _geocodesearch.delegate = nil; Here remember the time need to set nil, otherwise affect the release of memory
        _userlocation.delegate = nil;
        [_userlocation Stopuserlocationservice];
        _mapview.showsuserlocation = NO;
        _walkingrouteplanoption.delegate = nil;

When you use the

/**
 * Open Location Services
 *
/-(void) startuserlocationservice;

, it will callback the proxy method

/**
 * After the user orientation is updated, this function is called
 * @param userlocation New User location */
-(void) Didupdateuserheading: ( Bmkuserlocation *) userlocation;

There are some failures. Stop location and other agent methods please download Baidu SDK view.

-(void) Didupdateuserlocation: (bmkuserlocation *) userlocation{
    NSLog (@ "Latitude--%f,longtitude---%f", Userlocation.location.coordinate.latitude,userlocation.location.coordinate.longitude);
    Cllocationdegrees Localatitude;
    Cllocationdegrees Localongitude;
    localatitude=userlocation.location.coordinate.latitude;//Latitude
    localongitude= userlocation.location.coordinate.longitude;//Jing
    bmkcoordinateregion region;
    Centers the positioned point to display the
    region.center.latitude=localatitude;
    Region.center.longitude=localongitude;
    Region.span.latitudeDelta  = 0.01;
    Region.span.longitudeDelta = 0.01;
    [_mapview setregion:region Animated:no];
    
    Subcoor.latitude = Localatitude;
    Subcoor.longitude = Localongitude;
    [_mapview Setcentercoordinate:subcoor animated:yes];
}

Location can be determined based on the latitude and longitude obtained.

[Self geocode:[_latitude doublevalue] withlongitude:[_longitude Doublevalue]];

-(void) GeoCode: (double) latitude Withlongitude: (double) longitude{
    
    cllocationcoordinate2d pt = ( Cllocationcoordinate2d) {0, 0};
    PT = (cllocationcoordinate2d) {latitude, longitude};
    Bmkreversegeocodeoption *reversegeocodesearchoption = [[Bmkreversegeocodeoption alloc]init];
    Reversegeocodesearchoption.reversegeopoint = pt;
    BOOL flag = [_geocodesearch reversegeocode:reversegeocodesearchoption];
    
    if (flag)
    {
        NSLog (@ "anti-geo retrieval sent successfully");
    }
    else
    {
        NSLog (@ "anti-geo retrieval send Failed");}
}

which

 * @param Reversegeocodeoption Anti-geo Retrieval information class
 * @return successfully returned yes, otherwise no
 */
-(BOOL) Reversegeocode: ( bmkreversegeocodeoption*) reversegeocodeoption;

It then calls

/**

 @param Searcher Search Object
 * @param result search Result
 * @param error error number, @see bmksearcherrorcode< c10/>*/
-(void) Ongetreversegeocoderesult: (Bmkgeocodesearch *) Searcher Result: (Bmkreversegeocoderesult *) Result ErrorCode: (bmksearcherrorcode) error;

is the

-(void) Ongetreversegeocoderesult: (Bmkgeocodesearch *) Searcher Result: (Bmkreversegeocoderesult *) result ErrorCode: ( Bmksearcherrorcode) Error
{
	if (Error = = 0) {
        //
        Self.addarr = [NSString stringwithformat:@ "%@", Result.address];
        _pointannotation.subtitle =[nsstring stringwithformat:@ "Current location:%@", Self.addarr];
        if (_pointannotation = = nil) {
            [xccommonutility qqtshowalertmsg:@ ' cannot get the current position, please try again later];
            return;

        [Annotationarrays addobject:_pointannotation];
        [_mapview addannotations:annotationarrays];
        [Self seachwalkroute];
	}
}

Ps:

Result.address is the location that is obtained for the anti-geocoding. [Annotationarrays addobject:_pointannotation]; is an array of labels. When there are multiple annotations, add the labels to the array before adding them to the

[_mapview Addannotations:annotationarrays]; the end of the article will explain.

Walking route

The second method is basically to copy the official Deom directly behind the original found so convenient. At first, all of their own research, until the drawing of the walking route this piece of work for a long time finally did not get out to copy the demo and then slightly modified minutes to fix it.

The added annotations just mentioned can be used at both ends of the route.

Adding a callout must implement this proxy
