I am working on push notifications. I wrote the following code for fetching a device token.
-(BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[self.window addSubview:viewController.view];
[self.window makeKeyAndVisible];
NSLog(@"Registering for push notifications...");
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
return YES;
}
-(void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
NSString *str = [NSString stringWithFormat:@"Device Token=%@",deviceToken];
NSLog(@"This is device token%@", deviceToken);
}
-(void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err
{
NSString *str = [NSString stringWithFormat: @"Error: %@", err];
NSLog(@"Error %@",err);
}
Try this code :
// Register for Push Notification
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings // NS_AVAILABLE_IOS(8_0);
{
[application registerForRemoteNotifications];
}
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken{
NSLog(@"deviceToken: %@", deviceToken);
NSString * token = [NSString stringWithFormat:@"%@", deviceToken];
//Format token as you need:
token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
}
Note : simulator not return deviceToken, deviceToken only return in device with valid APNS certificate
In iOS 8 and iOS 9 you need to register for notifications like this:
NSLog(@"Registering for push notifications...");
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
Note that if you also want to support iOS 7, then you'll need to call your existing code on the earlier versions of iOS.
Enable " Push Notifications " in Xcode, this will fix the issue.
Targets -> Capabilities -> Push Notifications
Note: Provisioning Profiles Should be in Active State
Same issue happened with me So You have to use following code to get device token:-
- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@"<>"]];
token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"content---%@", token);
}
Even then it doesn't work Then please check your provisioning profile,it should be of that app ID by which you have created your ssl certificate for push notification.
Here is the latest code of swift 4.0, so you can use following code to get device token.
import UserNotifications
if #available(iOS 10, *) {
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]){ (granted, error) in
}
UIApplication.shared.registerForRemoteNotifications()
} else {
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let token = deviceToken.map { String(format: "%.2hhx", $0) }.joined()
}
Get device token
in Swift 3
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let token = String(format: "%@", deviceToken as CVarArg)
.trimmingCharacters(in: CharacterSet(charactersIn: "<>"))
.replacingOccurrences(of: " ", with: "")
print(token)
}
