[英]How to get the devicetoken in another class that is not the AppDelegate?
[英]ios DeviceToken: How to pass deviceToken from AppDelegate to ViewController?
我面临一些奇怪的问题。 实际上是在AppDelegate的didRegisterForRemoteNotificationsWithDeviceToken
方法之前调用的didRegisterForRemoteNotificationsWithDeviceToken
的didRegisterForRemoteNotificationsWithDeviceToken
方法
AppDelegate中的代码如下
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
NSLog(@"My token is: %@", deviceToken);
NSString* newToken = [deviceToken description];
newToken = [newToken stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
newToken = [newToken stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"token:%@",newToken);
NSUserDefaults *defaultValues = [NSUserDefaults standardUserDefaults];
[defaultValues setValue:newToken forKey:key_device_token];
[defaultValues synchronize];
}
ViewDidLoad方法的代码
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(@"ABCD");
}
以下是控制台输出

任何人都可以告诉我我的代码有什么问题吗?
没什么,您可以为应用程序注册“推送通知”,然后等待来自“ Apple”的令牌。 收到正常消息后,您的应用将首先创建您的ViewController 。
在方法中:
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
通知您有关令牌的ViewController 。 您有多种选择,找到哪种更适合您的应用程序体系结构。
如果您需要更多详细信息,请参阅有关APNS的出色教程: http ://www.raywenderlich.com/32960/apple-push-notification-services-in-ios-6-tutorial-part-1
完成didRegisterForRemoteNotificationsWithDeviceToken
,在AppDelegate中设置一个调用的委托方法。 将您的控制器附加到代理,因为通知将在注册后得到通知。
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
NSLog(@"My token is: %@", deviceToken);
NSString* newToken = [deviceToken description];
newToken = [newToken stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
newToken = [newToken stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"token:%@",newToken);
NSUserDefaults *defaultValues = [NSUserDefaults standardUserDefaults];
[defaultValues setValue:newToken forKey:key_device_token];
[defaultValues synchronize];
[[NSNotificationCenter defaultCenter] postNotificationName:@"profileUpdated" object:nil];
}
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(printDeviceID:)
name:@"profileUpdated"
object:nil];
}
- (void) printDeviceID:(NSNotification *) notification
{
if ([notification.name isEqualToString:@"profileUpdated"])
{
NSUserDefaults *defaultValues = notification.info;
}
}
