如何使用方法的设备令牌比didRegisterForRemoteNotificationsWithDeviceToken其他？ [英] How to use the device token in method other than didRegisterForRemoteNotificationsWithDeviceToken?

问题描述

我通过 didRegisterForRemoteNotificationsWithDeviceToken 方法的设备令牌。我想使用该设备令牌的另一种方法。我尝试了这种方式，

I got the device token through didRegisterForRemoteNotificationsWithDeviceToken method. I wanted to use the device token in another method. I tried it in this way,

在 didRegisterForRemoteNotificationsWithDeviceToken 方法：

str = [NSString stringWithFormat:@"%@",deviceToken];
// str is the NSString which is declared in the appDelegate.h file as global variable

在 didReceiveRemoteNotification 方法：

 NSLog(@"Device Token : %@",str);  

当我做这样的设备令牌正在恢复为nosniff。

When i do like this the Device Token is returning as "nosniff".

如何该设备令牌存储在一个全局变量和其他类或以其他方式使用。

How can i store this device token in a global variable and use it in the other class or in other method.

推荐答案

您可以添加设备令牌像这样的 NSUserDefaults的词典：

You can add the device token to the NSUserDefaults dictionary like so:

-(void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
    [[NSUserDefaults standardUserDefaults] setObject:deviceToken forKey:@"deviceToken"];

这然后可以在其他的方法来访问，像这样：

This can then be accessed in other methods like so:

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