ios - MultiPeer Framework Delegates Not Firing/Running (No UI) -


i've been stuck on problem while. i'm trying test multi peer framework. , i'm trying without ui. in other words, i'm inviting other peers manually through code. want able app come up, , peers automatically start looking each other , connect.

to set class named sidewaysmanager so: 

/**   sidewaysmanager.m */  #import "sidewaysmanager.h" #import "epbmyconfig.h"  @implementation sidewaysmanager {     nsstring *databasepath;      mcsession *currentsession;      mcnearbyservicebrowser *nearbybrowser;      mcnearbyserviceadvertiser *nearbyadvertiser;      nsstring *servicetype; }    - (id) init {      self = [super init];      if(self)     {          epbmyconfig *configinfo = [epbmyconfig instance];          nsstring *assetid = [configinfo getassetid];          nsstring *useagelocation = [configinfo getuseagelocation];          nsstring *peerdisplayname = [@"pctouchpad-" stringbyappendingstring:assetid];          if(![useagelocation isequaltostring:@""])         {             peerdisplayname = [peerdisplayname stringbyappendingstring: [nsstring stringwithformat:@"-%@", useagelocation]];         }          mcpeerid *localpeerid = [[mcpeerid alloc] initwithdisplayname:peerdisplayname];          currentsession = [[mcsession alloc] initwithpeer:localpeerid];         currentsession.delegate = self;          servicetype = @"epb-session";          nearbybrowser = [[mcnearbyservicebrowser alloc] initwithpeer:localpeerid servicetype:servicetype];         nearbybrowser.delegate = self;          nearbyadvertiser = [[mcnearbyserviceadvertiser alloc] initwithpeer:localpeerid discoveryinfo:nil servicetype:servicetype];         nearbyadvertiser.delegate = self;           nsarray *documentpaths = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes);          nsstring *documentdir = [documentpaths objectatindex:0];          databasepath = [documentdir stringbyappendingstring:@"/voterdb_prod"];          [nearbyadvertiser startadvertisingpeer];          [nearbybrowser startbrowsingforpeers];          return self;     }      return self;  }  /**   session delegates  */  // remote peer changed state - (void)session:(mcsession *)session peer:(mcpeerid *)peerid didchangestate:(mcsessionstate)state {     if(state == mcsessionstateconnected)     {         [nearbyadvertiser stopadvertisingpeer];         [nearbybrowser stopbrowsingforpeers];          nslog(@"peer connected session");     }     else if(state == mcsessionstatenotconnected)     {         nslog(@"peer not connected");     } }  // received data remote peer - (void)session:(mcsession *)session didreceivedata:(nsdata *)data frompeer:(mcpeerid *)peerid { }  // start receiving resource remote peer - (void)session:(mcsession *)session didstartreceivingresourcewithname:(nsstring *)resourcename frompeer:(mcpeerid *)peerid withprogress:(nsprogress *)progress { }  // finished receiving resource remote peer , saved content in temporary location - app responsible moving file permanent location within sandbox - (void)session:(mcsession *)session didfinishreceivingresourcewithname:(nsstring *)resourcename frompeer:(mcpeerid *)peerid aturl:(nsurl *)localurl witherror:(nserror *)error { }  - (void)session:(mcsession *)session didreceivecertificate:(nsarray *)certificate frompeer:(mcpeerid *)peerid certificatehandler:(void(^)(bool accept))certificatehandler {     nslog(@"received certificate");     certificatehandler(yes); }  - (void)session:(mcsession *)session didreceivestream:(nsinputstream *)stream withname:(nsstring *)streamname frompeer:(mcpeerid *)peerid {     stream.delegate = self;      [stream scheduleinrunloop:[nsrunloop mainrunloop] formode:nsdefaultrunloopmode];     [stream open];  }    /**  mcbrowser delegates  */  // found nearby advertising peer - (void)browser:(mcnearbyservicebrowser *)browser foundpeer:(mcpeerid *)peerid withdiscoveryinfo:(nsdictionary *)info {     nslog(@"found peer");      [browser invitepeer:peerid tosession:currentsession withcontext:nil timeout:0]; }  // nearby peer has stopped advertising - (void)browser:(mcnearbyservicebrowser *)browser lostpeer:(mcpeerid *)peerid {     nslog(@"lost peer"); }    /**advertising delegates  */  - (void)advertiser:(mcnearbyserviceadvertiser *)advertiser didreceiveinvitationfrompeer:(mcpeerid *)peerid withcontext:(nsdata *)context invitationhandler:(void(^)(bool accept, mcsession *session))invitationhandler {     invitationhandler(yes, currentsession); }   // advertising did not start due error - (void)advertiser:(mcnearbyserviceadvertiser *)advertiser didnotstartadvertisingpeer:(nserror *)error {     nslog(@"did not start advertising"); }   @end

and here's sidewaysmanager.h file:

#import <foundation/foundation.h> #import <multipeerconnectivity/multipeerconnectivity.h>  @interface sidewaysmanager : nsobject <mcnearbyserviceadvertiserdelegate, mcnearbyservicebrowserdelegate, mcsessiondelegate, nsstreamdelegate>   @end



, initialize class in appdelegate class. but, reason none of delegate methods above run. can 1 familiar framework me out or have idea why nothing happening in class? appreciate it.

i have created project based on single view application template. added sidewaysmanager code project. make compile removed epbmyconfig import , fixed compilation errors shown below:

//     epbmyconfig *configinfo = [epbmyconfig instance];   //     nsstring *assetid = [configinfo getassetid];  //     nsstring *useagelocation = [configinfo getuseagelocation];          nsstring *peerdisplayname = @"pctouchpad-test";  //    if(![useagelocation isequaltostring:@""]) //    { //        peerdisplayname = [peerdisplayname stringbyappendingstring: [nsstring stringwithformat:@"-%@", useagelocation]]; //    }        mcpeerid *localpeerid = [[mcpeerid alloc] initwithdisplayname:peerdisplayname];

running code on iphone , simulator delegates methods called , session created. seems setup of multipeer connectivity objects ok.

how create sidewaysmanager in appdelegate?

this how did it:

@interface pfappdelegate ()  @property (strong, nonatomic) sidewaysmanager *manager;  @end   @implementation pfappdelegate  - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     self.manager = [[sidewaysmanager alloc]init];     return yes; }

it important appdelegate class holds reference manager, otherwise de-alloced after didfinishlaunchingwithoptions returns. explain nothing happens in code.

alternatively, might problem in creation of peer display name (basically stuff commented out).

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...
