Question

Hi i want to implement GCM in iOS and i have my SenderID but i dont know where i have to implement SenderID.This is my entire code for GCM integration.i need TOKEN value.so please guide me to get it done.
Appdelegate :
#import "AppDelegate.h"
#interface AppDelegate ()
{
NSDictionary *RegistrationOptions;
NSString *GcmSenderID;
GGLInstanceIDTokenHandler registrationHandler;
}
#end
#implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
UIUserNotificationType allNotificationTypes=(UIUserNotificationTypeSound|UIUserNotificationTypeBadge);
UIUserNotificationSettings *settings=[UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
[[UIApplication sharedApplication]registerUserNotificationSettings:settings];
[[UIApplication sharedApplication]registerForRemoteNotifications];
return YES;
}
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
// Create a config and set a delegate that implements the GGLInstaceIDDelegate protocol.
GGLInstanceIDConfig *instanceIDConfig = [GGLInstanceIDConfig defaultConfig];
instanceIDConfig.delegate = self;
// Start the GGLInstanceID shared instance with the that config and request a registration
// token to enable reception of notifications
[[GGLInstanceID sharedInstance] startWithConfig:instanceIDConfig];
RegistrationOptions = #{kGGLInstanceIDRegisterAPNSOption:deviceToken,
kGGLInstanceIDAPNSServerTypeSandboxOption:#YES};
[[GGLInstanceID sharedInstance] tokenWithAuthorizedEntity:GcmSenderID
scope:kGGLInstanceIDScopeGCM
options:RegistrationOptions
handler:registrationHandler];
}
- (void)onTokenRefresh {
// A rotation of the registration tokens is happening, so the app needs to request a new token.
NSLog(#"The GCM registration token needs to be changed.");
[[GGLInstanceID sharedInstance] tokenWithAuthorizedEntity:GcmSenderID
scope:kGGLInstanceIDScopeGCM
options:RegistrationOptions
handler:registrationHandler];
}

Its pretty late answer.But it will help someone in future.
You just have to upload apns certificate (developer and production) and get the gcm config file and add it to your project (drag and drop to your project).
The following code which you should call in the didFinishLaunchingWithOptions will automatically fetch the _gcmSenderID from the config file.
_gcmSenderID = [[[GGLContext sharedInstance] configuration] gcmSenderID];
Here is a sample quick start project for you to start with.(both swift and objective-C).Everything is well explained in this sample app.Let me know if you have any doubts.
