MGTwitter发动机在iOS5中发生故障

虽然MGTwitterEngine在以前版本的iOS上运行良好，但在我尝试发布twit时，由于EXC_BAD_访问失败：

[twitter sendUpdate:textToShare];

Objective-C代码执行器的最后一个列表是：

[theRequest prepare];

内部SA_OAuthTwitterEngine.m。这是调用堆栈：

有什么想法吗？解决办法？ 你知道另一个适合iOS5的Twitter框架吗？我需要做的唯一一件事就是发布twits（当然可以先登录）

如上所述修改SA_OAuthTwitterEngine.m函数。

您基本上必须将oAuth URL更新为https。iOS5中的某些内容阻止它在生成设置中从http重定向到https

-all_load强制链接器从它看到的每个归档中加载所有对象文件，即使是那些没有Objective-C代码的文件-在Xcode 3.2及更高版本中提供了强制加载。它允许对归档加载进行更精细的控制。每个-force_load选项后面都必须有一个到归档文件的路径，该归档文件中的每个对象文件都将被加载

- (SA_OAuthTwitterEngine *) initOAuthWithDelegate: (NSObject *) delegate {
    if (self = (id) [super initWithDelegate: delegate]) {
        self.requestTokenURL = [NSURL URLWithString: @"https://twitter.com/oauth/request_token"];
        self.accessTokenURL = [NSURL URLWithString: @"https://twitter.com/oauth/access_token"];
        self.authorizeURL = [NSURL URLWithString: @"https://twitter.com/oauth/authorize"];
    }
    return self;
}
