ios - 如何在 applicationDidBecomeActive 中使用 deviceToken

Question

我可以在这里获取和使用设备 token :

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken {

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

}

我想在以下范围内获取/使用 deviceToken:

- (void)applicationDidBecomeActive:(UIApplication *)application
{
// How To GET/USE device Token Here?
}

您可以将设备 token 存储在 NSUserDefaults 中，因此您可以随时轻松获取它，

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{

    NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
    [[NSUserDefaults standardUserDefaults] setObject:token forKey:@"token"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}

现在您可以随时随地获取它，直到您的应用不被删除。

- (void)applicationDidBecomeActive:(UIApplication *)application
{

    NSString *token=[[NSUserDefaults standardUserDefaults]objectForKey:@"token"];
