twitpic API GSTwitPicEngine 在 setAccessToken 时出错 [英] twitpic API GSTwitPicEngine error while setAccessToken

问题描述

我尝试使用 GSTwitPicEngine 类 https://github.com/Gurpartap/GSTwitPicEngine 来分享图片在推特上
但它给出错误

I tried to use GSTwitPicEngine class https://github.com/Gurpartap/GSTwitPicEngine for sharing image on twitter
but its giving error

因为我们必须设置 [twitpicEngine setAccessToken:token];
如果我是对的，我使用 SA_OAuthTwitterEngine 类的 _accessToken 作为令牌

As we have to set [twitpicEngine setAccessToken:token];
if I am right, I am using _accessToken of class SA_OAuthTwitterEngine as token

_accessToken 在 SA_OAuthTwitterEngine 类中是私有的，我将它设置为 public 并且

_accessToken was private in class SA_OAuthTwitterEngine, I set it to public and also

@property (nonatomic, readonly) OAToken *accessToken;
@synthesize accessToken = _accessToken;

然后在行动

twitPicEngine = [GSTwitPicEngine twitpicEngineWithDelegate:self];
[twitPicEngine setAccessToken:twitterObj.accessToken];
[twitPicEngine uploadPicture:[shareDict objectForKey:@"image"] withMessage:[shareDict objectForKey:@"image_msg"]];

但是当 setAccessToken with log 时应用程序崩溃

But Application getting crash while setAccessToken with log

-[OAToken parameters]: unrecognized selector sent to instance 0x6327e30
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[OAToken parameters]: unrecognized selector sent to instance 0x6327e30'

如果你能发现任何错误，请帮忙

Please help if you able to find any thing wrong

推荐答案

不幸的是，GSTwitPicEngine 使用的 oauth-consumer 版本与神奇的 Twitter+Oauth 库 (SAOAuthTwitterEngine) 不同.我假设您正在使用该库向 Twitter 发布消息.

Unfortunately, GSTwitPicEngine is not using the same version of oauth-consumer than the fabulous Twitter+Oauth library (SAOAuthTwitterEngine). I assume you are using that library for posting messages to twitter.

崩溃是因为来自 Twitter+Oauth 的 OAToken 没有实现参数"方法.

The crash is because OAToken from Twitter+Oauth doesn´t implement the "parameters" method.

今天我整个上午都在调整几个库以避免崩溃.在这里，您可以下载我创建的示例项目，用于将 twitpic 照片发布到 Twitter 并附上消息.

Today I spent the entire morning tweaking the several libraries to avoid crashes. Here you can download a sample project I created for posting a twitpic photo to twitter with a message.

TestTwitpic

该项目拥有来自 github 的所有库的所有最新版本.

The project has all the latest versions of all libraries from github.

使我的 TestTwitpic 项目工作的说明:

在 TestTwitpic-Prefix.pch 中设置变量:

In TestTwitpic-Prefix.pch set the variables for:

#define kTwitterOAuthConsumerKey @""
#define kTwitterOAuthConsumerSecret @""
#define kTwitPicAPIKey @""

在 RootViewController 中，您可以根据需要更改这些行.更改照片:

In RootViewController you can change these lines to your needs. To change the photo:

//change [UIImage imageNamed:@"image.jpg"] for whatever UIImage you want to upload
//change @"my photo" for whatever title you want for your photo in twitpic website
[twitpicEngine uploadPicture:[UIImage imageNamed:@"image.jpg"] withMessage:@"my photo"];

和这个改变发送到推特的消息:

and this one to change message sent to twitter:

//I post to twitter the title of the photo and the twitpic url but you can post whatever you want
[engine sendUpdate:[NSString stringWithFormat:@"%@ %@", [[[response objectForKey:@"request"] userInfo] objectForKey:@"message"], [[response objectForKey:@"parsedResponse"] objectForKey:@"url"]]];

如果您想基于此示例创建自己的项目.执行以下操作:

1. 将包含所有库的 Twitpic 文件夹导入(拖放)到您的项目中.
2. 将这些框架添加到您的项目中:
   • 核心图形
   • libz.1.2.3
   • libxml2
   • MobileCoreServices
   • 系统配置
   • CFNetwork
   • 安全

如果你想知道我为修复库做了什么，我会或多或少告诉你我记得我做了什么:

1. 导入 Twitter+Oauth、GSTwitPicEngine、OARequestHeader、TouchJSON 和 ASIHTTPRequest 库.
2. 将 GSTwitPicEngine 设置为使用 TouchJSON 而不是 YAJL.
3. 添加了来自 oauth-consumer github 项目的 NSString+URLEncoding 类别，因为 OARequestHeader 缺少它.
4. 使用以下行修改 OARequestHeader 内所有出现的 NSDictionary* foo = [toke parameters]:
   • NSDictionary *foo = [NSDictionary dictionaryWithObject:[token key] forKey:@"oauth_token"];

1. Import Twitter+Oauth, GSTwitPicEngine, OARequestHeader, TouchJSON, and ASIHTTPRequest libraries.
2. Set GSTwitPicEngine to use TouchJSON instead of YAJL.
3. Added the category NSString+URLEncoding from oauth-consumer github project as OARequestHeader was missing it.
4. Modified all occurrences of NSDictionary* foo = [toke parameters] inside OARequestHeader with the line:
   • NSDictionary *foo = [NSDictionary dictionaryWithObject:[token key] forKey:@"oauth_token"];

• 更改行:
  • response = [[CJSONDeserializer deserializer] deserialize:responseString error:&error];
  • response = [[CJSONDeserializer deserializer] deserialize:[responseString dataUsingEncoding:NSUTF8StringEncoding] error:&error];
