ios - 未收到设备 token

Question

我在使用此代码获取设备 token 时收到此警告消息。

"Error Domain=NSCocoaErrorDomainCode=3000"no valid aps-environment'entitlement string found for application" Userinfo=0x1665f5b0 {NSlocalizedDescription=no valid 'app-environment'entitlement string found for application}

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)var_deviceToken
{

    NSString *tokenString = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    NSLog(@"Push Notification tokenstring is %@",tokenString);
    self.deviceToken = tokenString;


 }

 - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
 {

     NSString* s=[[NSString alloc] initWithFormat:@"%@",error];
     UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Device Token didn't recieve" message:s delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
     [alert show];

 }

出现这个问题的原因是，

1. 您没有在您的临时配置文件中启用推送通知。
2. 如果启用，您可能会忘记使用该 bundle 标识符和移动设备。
