获取推送通知的设备令牌

我正在研究推送通知。我编写了以下代码来获取设备令牌。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    // Override point for customization after application launch.

    // Add the view controller's view to the window and display.
    [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);    
}

我能够在设备上成功运行应用程序,但无法在控制台上获取设备ID。

我对认证和配置文件没有任何问题。

您必须使用以下代码来获取设备令牌: -

Objective-C的

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 
{
    NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSLog(@"content---%@", token);
} 

Swift 3.0

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
    let   tokenString = deviceToken.reduce("", {$0 + String(format: "%02X",    $1)})
    // kDeviceToken=tokenString
    print("deviceToken: \(tokenString)")
}

要获得令牌设备,你可以通过一些 步骤

1)为开发人员认证和分发认证启用APNS(Apple推送通知服务),然后重新下载这两个文件。

2)重新下载Developer Provisioning和Distribute Provisioning文件。

3)在Xcode界面中:为具有两个文件配置的PROJECT和TARGETS设置配置已下载。

4)最后,您需要在AppDelegate文件中添加以下代码以获取令牌设备(注意:在真实设备中运行应用程序)。

- (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(@"%@", str);
}

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { 
     NSString *str = [NSString stringWithFormat: @"Error: %@", err];
     NSLog(@"%@",str);
}

以下代码用于检索设备令牌。

    // Prepare the Device Token for Registration (remove spaces and < >)
    NSString *devToken = [[[[deviceToken description] 
                            stringByReplacingOccurrencesOfString:@"<"withString:@""] 
                           stringByReplacingOccurrencesOfString:@">" withString:@""] 
                          stringByReplacingOccurrencesOfString: @" " withString: @""];


    NSString *str = [NSString 
                     stringWithFormat:@"Device Token=%@",devToken];
    UIAlertView *alertCtr = [[[UIAlertView alloc] initWithTitle:@"Token is " message:devToken delegate:self cancelButtonTitle:nil otherButtonTitles: nil] autorelease];
    [alertCtr show];
    NSLog(@"device token - %@",str);

还有Swif版本的Wasif的答案:

Swift 2.x

var token = deviceToken.description.stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "<>"))
token = token.stringByReplacingOccurrencesOfString(" ", withString: "")
print("Token is \(token)")

Swift 3的更新

let deviceTokenString = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()

如果您仍未获得设备令牌,请尝试输入以下代码,以便注册您的设备以获取推送通知。

它也适用于ios8或更高版本。

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000

    if ([UIApplication respondsToSelector:@selector(registerUserNotificationSettings:)]) {
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound
                                                                                 categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    } else {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         UIRemoteNotificationTypeBadge |
         UIRemoteNotificationTypeAlert |
         UIRemoteNotificationTypeSound];

    }
#else
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     UIRemoteNotificationTypeBadge |
     UIRemoteNotificationTypeAlert |
     UIRemoteNotificationTypeSound];

#endif

在你的Appdelegate中,在didRegisterForRemoteNotificationsWithDeviceToken方法中:

NSString *deviceTokenString = deviceToken.description;
deviceTokenString = [deviceTokenString stringByReplacingOccurrencesOfString:@"[< >]" withString:@"" options:NSRegularExpressionSearch range:NSMakeRange(0, deviceTokenString.length)];
NSLog(deviceTokenString.description);

在构建设置中设置代码签名配置文件如果您有APN启用证书,那么您肯定会获得令牌ID。并删除

配置文件:自动

并设置为

配置文件:您的配置文件证书。

在Swift 3中获取设备令牌

 func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let token = String(format: "%@", deviceToken as CVarArg).trimmingCharacters(in: CharacterSet(charactersIn: "<>")).replacingOccurrences(of: " ", with: "")
        print(token)
    }

在Swift 3中获取设备令牌

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

    let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})

    print("Device token: \(deviceTokenString)")

为了使设备令牌使用以下代码,您只能使用物理设备获取设备令牌。如果您必须在使用模拟器时发送设备令牌,则可以使用以下条件。

  if(!(TARGET_IPHONE_SIMULATOR))
    {
        [infoDict setValue:[[NSUserDefaults standardUserDefaults] valueForKey:@"DeviceToken"] forKey:@"device_id"];
    }
    else
    {
        [infoDict setValue:@"e79c2b66222a956ce04625b22e3cad3a63e91f34b1a21213a458fadb2b459385" forKey:@"device_id"];
    }



- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
    NSLog(@"My token is: %@", deviceToken);
    NSString * deviceTokenString = [[[[deviceToken description] stringByReplacingOccurrencesOfString: @"<" withString: @""] stringByReplacingOccurrencesOfString: @">" withString: @""]   stringByReplacingOccurrencesOfString: @" " withString: @""];
    NSLog(@"the generated device token string is : %@",deviceTokenString);
    [[NSUserDefaults standardUserDefaults] setObject:deviceTokenString forKey:@"DeviceToken"];
}
