Rails 3 和苹果推送通知服务

有没有人能够使用 rails 3 向 iPhone 发送推送通知?仅限 APN on rails 和 samesoffes 插件使用 rails 2.我是 rails 的新手，我无法使它们中的任何一个工作.

Has anybody been able to send push notification to iPhone using rails 3 ? APN on rails and samesoffes plugin only works with rails 2. I am new to rails and i have not been able to make either of them work.

以下是我遇到的错误:

Rails 上的 APN:

APN on Rails :

试图替换

ruby script/generate apn_migrations

与

rails generate apn_migrations

得到:

myApp/config/environment.rb:5:in`require':没有要加载的文件--apn_on_rails(加载错误)

myApp/config/environment.rb:5:in `require': no such file to load -- apn_on_rails (LoadError)

我也没有设法运行配置config.gem 'apn_on_rails'"(config.gem:找不到命令)

I also did not manage to run the configuration "config.gem 'apn_on_rails'" (config.gem: command not found)

Samsoffes 插件:

Samsoffes plugin :

我没有设法配置 gem :

I did not manage to config the gem :

config.gem "apple_push_notification", :source => "http://gemcutter.org/"

给了我:

http://gemcutter.org/:没有这样的文件或目录

http://gemcutter.org/: No such file or directory

任何帮助将不胜感激！

谢谢，文森特
