iphone - Cant get new location after stopUpdatingLocation - IOS -

i'm trying users gps coordinates app, works fine, once. when view gets called run code , location - - when view want new coordinates old ones chashed in phone.

here code:

#import "postpictureviewcontroller.h"  @interface postpictureviewcontroller ()  @end  @implementation postpictureviewcontroller  {     cllocationmanager *locationmanager; }  - (id)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil {     self = [super initwithnibname:nibnameornil bundle:nibbundleornil];     if (self) {         // custom initialization     }     return self; }  - (void)viewdidload {     [super viewdidload];            }  -(void) viewdidappear:(bool)animated{     locationmanager = [[cllocationmanager alloc] init];     [self getlocation]; }  -(void)getlocation{     locationmanager.delegate = self;     locationmanager.desiredaccuracy = kcllocationaccuracybest;      [locationmanager startupdatinglocation]; }  - (void)didreceivememorywarning {     [super didreceivememorywarning];     // dispose of resources can recreated. }  #pragma mark - cllocationmanagerdelegate  - (void)locationmanager:(cllocationmanager *)manager didfailwitherror:(nserror *)error {     nslog(@"didfailwitherror: %@", error);     uialertview *erroralert = [[uialertview alloc]                                initwithtitle:@"fel" message:@"error" delegate:nil cancelbuttontitle:@"ok" otherbuttontitles:nil];     [erroralert show]; }  - (void)locationmanager:(cllocationmanager *)manager didupdatetolocation:(cllocation *)newlocation fromlocation:(cllocation *)oldlocation {     nslog(@"didupdatetolocation: %@", newlocation);     cllocation *currentlocation = newlocation;      if (currentlocation != nil) {         nslog([nsstring stringwithformat:@"%.8f", currentlocation.coordinate.longitude]);         nslog([nsstring stringwithformat:@"%.8f", currentlocation.coordinate.latitude]);     }     // stop location manager     [locationmanager stopupdatinglocation]; //this screwing     locationmanager = nil; } 

.h

#import <uikit/uikit.h> #import <corelocation/corelocation.h>  @interface postpictureviewcontroller : uiviewcontroller<cllocationmanagerdelegate>  @end 

i think problem [locationmanager stopupdatinglocation]; line stop locationmanager after getting coordinates first time. have tried without line , works - updates coordinates - dont want locationmanager send me new coordinates every second. need them once per view-time.

anyone got clue? in advance

try in way:

- (void)viewdidload {  [super viewdidload];     locationmanager = [[cllocationmanager alloc] init];  [self getlocation]; }  -(void) viewwillappear:(bool)animated{  [locationmanager startupdatinglocation]; }  -(void)getlocation{  locationmanager.delegate = self;  locationmanager.desiredaccuracy = kcllocationaccuracybest; }  - (void)didreceivememorywarning {  [super didreceivememorywarning];  // dispose of resources can recreated. }  #pragma mark - cllocationmanagerdelegate  - (void)locationmanager:(cllocationmanager *)manager didfailwitherror:(nserror *)error {  nslog(@"didfailwitherror: %@", error);  uialertview *erroralert = [[uialertview alloc]                            initwithtitle:@"fel" message:@"error" delegate:nil cancelbuttontitle:@"ok" otherbuttontitles:nil]; [erroralert show]; }  - (void)locationmanager:(cllocationmanager *)manager didupdatetolocation:(cllocation *)newlocation fromlocation:(cllocation *)oldlocation {  nslog(@"didupdatetolocation: %@", newlocation);  cllocation *currentlocation = newlocation;   if (currentlocation != nil) {     nslog([nsstring stringwithformat:@"%.8f", currentlocation.coordinate.longitude]);     nslog([nsstring stringwithformat:@"%.8f", currentlocation.coordinate.latitude]);  }  // stop location manager  [locationmanager stopupdatinglocation]; //this screwing }  - (void)viewdidunload {  locationmanager = nil; }
