MGTwitterEngine Error in iOS5

Question

Although MGTwitterEngine works well in previous versions of iOS, it failed with EXC_BAD_ACCESS the moment I try to send a twit message:

[twitter sendUpdate:textToShare]; 

The latest list of Objective-C code executer:

 [theRequest prepare]; 

inside SA_OAuthTwitterEngine.m. This is the call stack:

Any ideas? Workaround Do you know another Twitter infrastructure that works well with iOS 5? The only thing I need to do with this is post twits (with login first, of course).

Answer 1

 - (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; } 

Modify the SA_OAuthTwitterEngine.m function as described above. You basically have to update oAuth URLs to https. Something in iOS5 doesn't allow redirecting https from http

Answer 2

You can try applying the changes from this commit https://github.com/Hoya/Twitter-OAuth-iPhone/commit/8b3bb836f71b8fd49e41c3f0a66bfb81bec72634 . As I understand it, this is exactly what you need.

Answer 3

add -all_load flag in build setup

https://developer.apple.com/library/mac/#qa/qa2006/qa1490.html

-all_load forces the linker to load all object files from each archive being viewed, even without Objective-C code. -force_load is available in Xcode 3.2 and later. This allows you to control the granularity of the granary. Each option -force_load must be followed by the path to the archive, and each object file in this archive will be loaded.
