如何将sinaweibo demo project 加入到 Three20UI中
想将sinaweibo demo project 加入到 Three20UI中，当用户点击thumb photo 相册的时候，一张放大的图片上加上sinaweibo图标。现在点击sinaweibo图标，可以出现 OAuth 及 XAuth 选择界面，再点击OAuth 时，App crashes.点击 XAuth 时，出现用户名及密码登录界面，输入后，程序同样崩溃。
用的是下面的代码：
- (void)clickActionItem {} in the three20UI as follows: - (void)clickActionItem { SinaWeiBoSDKDemoViewController *sinaWeiBoSDKDemoViewController = [[[SinaWeiBoSDKDemoViewController alloc] initWithNibName:@"SinaWeiBoSDKDemoViewController" bundle:nil] autorelease]; [self.navigationController pushViewController:sinaWeiBoSDKDemoViewController animated:YES]; }
问题出在这里：[pairs addObject:[NSString stringWithFormat:@"%@=%@", key, [[dict objectForKey:key] URLEncodedString]]];
找到了URLEncodedString 的定义，而且我的项目已经引用了这个定义，可为什么还报错哪？如何修改哪？ 谢谢！
It is defined in the WBUtil.m ( which is already included in the Three20UI ) as :
- (NSString *)URLEncodedString
{
return [self URLEncodedStringWithCFStringEncoding:kCFStringEncodingUTF8];
}
