从Xcode 3.2.2到Xcode 3.2.3

[英]From Xcode 3.2.2 to Xcode 3.2.3

Yesterday I felt in big issue that happens with all my projects. 昨天,我感到所有项目都遇到了重大问题。 After I installed new Xcode 3.2.3 (for iPhone OS 4), all my projects started to spit out the "referenced from:" errors. 安装新的Xcode 3.2.3(适用于iPhone OS 4)之后,我的所有项目开始吐出“ referenced from:”错误。 I noticed that in new Xcode all the iPhone SDK versions earlier than 3.2 removed. 我注意到在新的Xcode中,所有早于3.2的iPhone SDK版本都已删除。 But I have a projects that built perfectly for iPhone SDK 3.2 on the Xcode 3.2.2 but has errors building for iPhone SDK 3.2 on the Xcode 3.2.3. 但是我有一个专为Xcode 3.2.2上的iPhone SDK 3.2完美构建的项目,但是有一个专为Xcode 3.2.3上的iPhone SDK 3.2构建的错误。

Thanks in advance!!! 提前致谢!!!

I've narrowed the range of the issue and now I see that this issue happens because of Reachability class, although it was copied from official apple sample. 我已经缩小了问题的范围,现在我看到由于可及性类而发生了该问题,尽管它是从官方的苹果样本中复制的。 I think that the apple developers just removed the links to some standard libraries. 我认为苹果开发人员只是删除了一些标准库的链接。 But what links??? 但是什么链接??? Anyway, I'm sure that someone saw this issue, because it's caused by Reachability (99% use this class)! 无论如何,我敢肯定有人看到了这个问题,因为它是由可达性引起的(99%使用此类)!

Many Thanks in Advance! 提前谢谢了!

the errors of type "referenced from:" just means that some framework should be added. 类型“引用自:”的错误仅表示应添加一些框架。 and it works with Reachability class (just need to add SystemConfiguration framework). 并且它与Reachability类一起工作(只需要添加SystemConfiguration框架)。 But the twitter api refused to work. 但是twitter api拒绝工作。 That's why all my old projects refused to compile on new Xcode - because the Twitter api (MGTwitterEngine) do not work for OS4 (Xcode 3.2.3). 这就是为什么我所有的旧项目都拒绝在新的Xcode上编译的原因-因为Twitter api(MGTwitterEngine)在OS4(Xcode 3.2.3)上不起作用。 :( It's really really bad :(( :(这真的很糟糕:((
