iOS device targeting

First, iOS talks about positioning

1, SignInSignOutViewController.h

@interface signinsignoutviewcontroller:uiviewcontroller<cllocationmanagerdelegate>{    CLLocationManager *_locationmanager;    Latitude    float _latitude;    Longitude    float _longitude;} @property (Nonatomic,retain) Cllocationmanager *locationmanager; @property (nonatomic) float latitude; @property ( nonatomic) float longitude; @end

2, SIGNINSIGNOUTVIEWCONTROLLER.M

#import "SignInSignOutViewController.h" @interface Signinsignoutviewcontroller () @end @implementation Signinsignoutviewcontroller@synthesize Locationmanager = _locationmanager; @synthesize latitude = _latitude;@    Synthesize longitude = _longitude;-(void) dealloc{Self.locationmanager = nil; [Super Dealloc];}    -(void) viewdidunload{[Super Viewdidunload]; Self.locationmanager = nil;}    -(void) viewdidload{[Super Viewdidload];    Instantiate a location manager cllocationmanager *cllocationmanager = [[Cllocationmanager alloc] init];    Self.locationmanager = Cllocationmanager;    [Cllocationmanager release];    Self.locationManager.delegate = self;    Self.locationManager.desiredAccuracy = Kcllocationaccuracybest;    [Self.locationmanager startupdatinglocation]; if (![     Cllocationmanager locationservicesenabled]) {[Globalapplication alert:@ ' prompt ': @ ' please turn on location: Settings > Privacy > Locations > Location Services];     }else{if ([Cllocationmanager authorizationstatus]! = kclauthorizationstatusauthorized) {       [Globalapplication alert:@ "prompt": @ "Location failed, please turn on location: Settings > Privacy > Location > Positioning service under XX application"]; }}} #pragma mark-cllocationmanagerdelegate#pragma mark-cllocationmanagerdelegate//triggered when the geographic location changes-(void) Locationmana GER: (Cllocationmanager *) Manager didupdatetolocation: (cllocation *) newlocation fromlocation: (cllocation *)    oldlocation{cllocationcoordinate2d CC,CC2;    Get latitude and longitude cc.longitude = newLocation.coordinate.longitude;    Cc.latitude = NewLocation.coordinate.latitude;    iOS coordinates (Google) converted to baidu coordinates CC2 = Bmkcoordictionarydecode (BMKBAIDUCOORFORWGS84 (cc));    Self.longitude = Cc2.longitude;    Self.latitude = Cc2.latitude; Stop location update [manager stopupdatinglocation];} Trigger when positioning error-(void) Locationmanager: (Cllocationmanager *) Manager didfailwitherror: (nserror *) error{NSString *    errorstring;    [Manager Stopupdatinglocation]; switch ([error code]) {Case kclerrordenied:errorstring = @ "Location failed, please turn on location: Settings > Privacy > Location > Positioning Services XX            Application "; Errorstring = @ "Access to location Services denied by user";        Break            Case kclerrorlocationunknown:errorstring = @ "Failed to locate, location data not available";        Break            default:errorstring = @ "Location failed, unknown error";    Break } [globalapplication alert:@ "positioning": errorstring];}

Second, Baidu map positioning (version number 2.1)

1,MainMenuViewController.h

@interface mainmenuviewcontroller:uiviewcontroller<bmkuserlocationdelegate> {    bmkuserlocation *_ MapLocation;    Latitude    float _latitude;    Longitude    float _longitude;} @property (nonatomic, retain) bmkuserlocation *maplocation; @property (nonatomic) float latitude; @property (nonatomic) float longitude; @end

2, MAINMENUVIEWCONTROLLER.M

#import "MainMenuViewController.h" @interface Mainmenuviewcontroller () @end @implementation Mainmenuviewcontroller@synthesize maplocation = _maplocation; @synthesize latitude = _latitude; @synthesize Longitude = _ longitude;    -(void) dealloc{self.maplocation = nil;    [Super Dealloc];    }-(void) viewdidunload{[Super Viewdidunload]; Self.maplocation = nil;}    -(void) viewdidload{[Super Viewdidload];    Bmkuserlocation *bmklocation = [[Bmkuserlocation alloc] init];    Bmklocation.delegate = self;    Self.maplocation = bmklocation;    [Bmklocation release]; [Self.maplocation Startuserlocationservice];} #pragma mark-baidu map/** * Call this function when the startuserlocationservice is positioned successfully * @param userloc my position coordinates */-(void)         Viewdidgetlocatinguser: (cllocationcoordinate2d) userloc{if (userloc.longitude! = 0 && Userloc.latitude! = 0) {        Self.longitude = Userloc.longitude;        Self.latitude = Userloc.latitude;    [Self.maplocation Stopuserlocationservice]; }}

iii. Results Method One:
ios:xxx.151604,xx.170156 (coordinates of the iOS collection)
baidu:xxx.162720,xx.174000 (Baidu conversion coordinates)
Method Two:
baidu:xxx.162716,xx.173980 (coordinates Baidu Collection)
