objective c - Google sign-in SDK 2.0.1 for iOS error -

-

i'm trying integrate google sign-in in project i'm using 'google sign-in sdk 2.0.1'. have follow steps shown on developer.google site when click on button returns error 'unknown error' in - (void)signin:(gidsignin *)signin didsigninforuser:(gidgoogleuser *)user witherror:(nserror *)error

i have integrated 2 url schemes , app-delegate,vc implementation shown in tutorial

here code viewcontroller implement sign-in button

@interface viewcontroller () < gidsigninuidelegate,gidsignindelegate> @property (weak, nonatomic) iboutlet gidsigninbutton *btnsignin;  @end  @implementation viewcontroller  - (void)didreceivememorywarning {     [super didreceivememorywarning];     // dispose of resources can recreated. }  - (void)viewdidload {     [super viewdidload];     [gidsignin sharedinstance].uidelegate = self;     [gidsignin sharedinstance].delegate = self;  }  // ---------------------------------------------------------------------  #pragma mark - gidsignindelegate  - (void)signin:(gidsignin *)signin didsigninforuser:(gidgoogleuser *)user      witherror:(nserror *)error {     if (error) {         nslog(@"error in signin %@",[error localizeddescription]);         return;     } }  // ---------------------------------------------------------------------   - (void)signin:(gidsignin *)signin diddisconnectwithuser:(gidgoogleuser *)user      witherror:(nserror *)error {     if (error) {         nslog(@"error did disconnect %@",[error localizeddescription]);         return;     } }  @end

what specific error code? generally, see message returned along exception:

2015-06-18 16:36:49.463 signinexample[20038:2727845] *** terminating app due uncaught exception 'nsinvalidargumentexception', reason: 'your app must support following url schemes: (null)'

a few things diagnose in meantime:

  • you might want start the google sign-in quickstart running pod try google , use [[gglcontext sharedinstance] configurewitherror: &configureerror]; configure project

  • if not calling configurewitherror, should setting client id, typically done in appdelegate, example:

    [gidsignin sharedinstance].clientid = "your_client_id";

  • look @ web browser address (if you're testing in simulator) make sure client id getting passed sign in flow

  • make sure add reversed client id url schemes

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
