ios - Show User's current location on map -

i trying display user's current location on map reason, not takes default coordinates.

i have mkmapview class called inside uiviewcontroller.

mapview.h

#import <uikit/uikit.h> #import <mapkit/mapkit.h> #import <corelocation/corelocation.h>  @interface mapview : mkmapview <mkmapviewdelegate, cllocationmanagerdelegate>{      cllocationmanager *locationmanager; }  @end 

mapview.m

#import "mapview.h"  @interface mapview ()  @end  @implementation mapview  - (id)initwithframe:(cgrect)frame{      self = [super initwithframe:frame];     if (self) {          locationmanager = [[cllocationmanager alloc] init];         locationmanager.delegate = self;          self.delegate = self;          [self addannotation:[self userlocation]];         [locationmanager startupdatinglocation];     }     return self; }  - (void)locationmanager:(cllocationmanager *)manager didfailwitherror:(nserror *)error {     nslog(@"didfailwitherror: %@", error);     uialertview *erroralert = [[uialertview alloc]                                initwithtitle:@"error" message:@"failed location" delegate:nil cancelbuttontitle:@"ok" otherbuttontitles:nil];     [erroralert show]; }  - (void)mapview:(mkmapview *)mapview didupdateuserlocation:(mkuserlocation *)userlocation {     nslog(@"didupdateuserlocation");      mkcoordinateregion region = mkcoordinateregionmakewithdistance(userlocation.coordinate, 250, 250);     [self setregion:[self regionthatfits:region] animated:yes];      mkpointannotation *point = [[mkpointannotation alloc] init];     point.coordinate = userlocation.coordinate;     point.title = @"where i?";     point.subtitle = @"i'm here!!!";      [self addannotation:point]; }  - (mkannotationview*)mapview:(mkmapview *)mapview viewforannotation:(id<mkannotation>)annotation{     nslog(@"viewforannotation");     static nsstring *identifier = @"myannotation";      if ([annotation iskindofclass:[mkuserlocation class]]) {         nslog(@"is user %f, %f", [annotation coordinate].latitude, [annotation coordinate].longitude);         return nil;     }      return nil; }  - (void)mapview:(mkmapview *)mapview didaddannotationviews:(nsarray *)views{     nslog(@"didaddannotationviews");     (mkannotationview *view in views){         if ([[view annotation] iskindofclass:[mkuserlocation class]]){              mkcoordinateregion region = mkcoordinateregionmakewithdistance([[view annotation] coordinate] , 250, 250);              [mapview setregion:region animated:yes];         }     } }  @end 

i getting output below once access map.

viewforannotation user 0.000000, 0.000000 didaddannotationviews 

i can't understand why didupdateuserlocation: never called if re-submit custom coordinates.

what missing here?

you're using cllocationmanager , setting it's delegate, delegate methods methods of mkmapviewdelegate.

you can either set mapview's delegate, or use locationmanager:didupdatelocations: cllocationmanagerdelegate method.
