我在我的应用程序中添加了将图像上传到 Flickr 的功能。我正在使用 ObjectiveFlickr 并使用 SnapAndRun 示例代码，并让它工作。唯一的问题是，它看起来很丑。
我很少做很多网络编码，所以这有点难以理解。
使用 OAuth 授权我的应用程序似乎要通过这么多功能......必须有一种更清洁的方式。
我曾考虑过使用积木，但我没有很好地处理它。
我基本上有一个 5 步过程，从一个函数开始，将一些东西发送到 Flickr，Flickr 在另一个函数中返回并调用另一个函数，然后不断地......请求令牌......等待回复，建立一个 webview确认...获取另一个令牌...更多等待...最后点击我的上传代码。
有没有人以更清洁的方式做到这一点？我想要一个小方向。
非常感谢。
我在使用 tumblr 进行身份验证时面临同样的问题。我找到了使用 oauth-consumer 的解决方案。您可以从git或google-group下载它。
您必须在此处CONSUMER_KEY注册 flicker api，然后才能CONSUMER_SECRET从那里获取。
#define CONSUMER_KEY @"your consumer key here"
#define CONSUMER_SECRET @"your secret key here"
#define authorize_url @"http://www.flickr.com/services/oauth/authorize"
#define request_token_url @"http://www.flickr.com/services/oauth/request_token"

如果它需要任何额外的参数，你可以从这里获得。
OAuth 的 Flickr 指南看起来很清楚，但是如果你想看一个例子，有一个 github 项目Flickr iOS OAuth 。
