ios - Send device token to PHP script via UIWebView -

i working on transit web app used san diego's metropolitan transit system. ios, planning on using tabbar 3 items, [home] [favorites] [notifications]. [home] leads main page (and other pages), [favorites] can setup favorite bus/trolley stops.

i planning on having [favorites] can setup notification sent before bus arrives @ scheduled times provided mts. example, if bus come @ 10:30 , set notification arrive 5 minutes before alert you, 1 @ 10:25.

i wanting link accounts device tokens, , read of questions on here such linking user account device token push notifications.

i believe possible somehow link accounts sending device token uiwebview when login.

hope can me.

edit: below obj-c code in home.m

#import "home.h"  @implementation homeviewcontroller  - (void)viewdidload {     [super viewdidload];      nsurl *url1 = [nsurl urlwithstring:@"url"];      nsurlrequest *request1 = [nsurlrequest requestwithurl:url1];      [webview1 loadrequest:request1];  }  - (void)webviewdidfinishload:(uiwebview *)webview {     nslog(@"1");     nsuserdefaults *defaults =[nsuserdefaults standarduserdefaults];     nsstring *devicetoken = [defaults objectforkey:@"devicetoken"];     bool tokenissent = [defaults boolforkey:@"tokenissent"];     nsstring *newtoken = [defaults stringforkey:@"newtoken"];     nslog(@"2");     nsstring *urlstring = [nsstring stringwithformat:@"url"];     nsurl *url = [[nsurl alloc] initwithstring:urlstring];     nsurlrequest *urlrequest = [nsurlrequest requestwithurl:url];     nsdata *usernamedata;     nsurlresponse *response;     usernamedata = [nsurlconnection sendsynchronousrequest:urlrequest returningresponse:&response error:nil];     nsstring *username = [[nsstring alloc] initwithdata:usernamedata encoding:nsutf8stringencoding];     nslog(@"3");      if (devicetoken != nil && tokenissent == no) {         nslog(@"4");         nsstring *urlstring = [nsstring stringwithformat:@"url/s=%@&u=%@",newtoken, username];         nsurl *url = [[nsurl alloc] initwithstring:urlstring];         nsurlrequest *urlrequest = [nsurlrequest requestwithurl:url];         nsdata *urldata;         nsurlresponse *response;         urldata = [nsurlconnection sendsynchronousrequest:urlrequest returningresponse:&response error:nil];         nsstring *info = [[nsstring alloc] initwithdata:urldata encoding:nsutf8stringencoding];         if([info  isequal: @"success"]){             [defaults setbool:yes forkey:@"tokenissent"];             nslog(@"5");         }else{             [defaults setbool:no forkey:@"tokenissent"];             nslog(@"6");         }         [defaults synchronize];     } else {         nslog(@"7");     }  } 

first save token nsuserdefaults

-(void)application:(uiapplication *)application didregisterforremotenotificationswithdevicetoken:(nsdata *)devicetoken {     nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults];     [defaults setobject:devicetoken forkey:@"devicetoken"];     [defaults setbool:no forkey:@"tokenissent"];     [defaults synchronize]; } 

because done in appdelegate, @ point user not logged in yet, that's why need track using value in example above tokenissent , set no (false).

now once user authenticates, can send sever , associated user.

nsuserdefaults *defaults =[nsuserdefaults standarduserdefaults]; bool devicetoken = [defaults boolforkey:@"devicetoken"]; bool tokenissent = [defaults boolforkey:@"tokenissent"];  if (devicetoken != nil && tokenissent) {  // not null , , not sent php send         if(success){             [defaults setbool:yes forkey:@"tokenissent"];         }else{             [defaults setbool:no forkey:@"tokenissent"];         }         [defaults synchronize]; }

if delgate not being called need implement it:

@interface homeviewcontroller : uiviewcontroller<uiwebviewdelegate> 

and make sure assign delegate.

- (void)viewdidload {     [super viewdidload];      //assign delegate webview1     webview1.delegate = self      //perform request     nsurl *url1 = [nsurl urlwithstring:@"http://clovercloud.net/app/f/"];     nsurlrequest *request1 = [nsurlrequest requestwithurl:url1];     [webview1 loadrequest:request1];  }
