Q: How do I fix "selector not recognized" runtime exceptions when trying to use category methods from a static library? 如何解决 在 runtime 环境中尝试调用静态库中分类的方法时,报 "selector not recognized" 异常?   今天在浏览 YYKit 库时,一个宏定义引起了我的注意:YYSYNTH_DUMMY_CLASS,…

https://developer.apple.com/library/mac/qa/qa1490/_index.html    之所以使用该标志,和Objective-C的一个重要特性:类别(category)有关.根据这里的解释,Unix的标准静态库实现和Objective-C的动态特性之间有一些冲突:Objective-C没有为每个函数(或者方法)定义链接符号,它只为每个类创建链接符号.这样当在一个静态库中使用类别来扩展已有类的时候,链接器不知道如何把类原有的方法和类别中的方法整合起来,就…

Using Open Source Static Libraries in Xcode 4 Xcode 4.0.1 allows us to more easily create and use third party libraries in iOS projects. I think the process is still more complicated than it needs to be. Xcode's documentation suggests that it should…

在<Objective C类方法load和initialize的区别>一文中,我介绍了Objective-C对待+(void)initialize和+(void)load两个方法在编译和执行时出现的不同.而这些不同也是在使用时应该非常注意的地方.不过文章里面我没有讲这两个方法在Objective-C中究竟有什么实用价值. 其实+(void)initialize可以视为C#,Java中的静态构造函数.有了这个方法,我们就不用像C++自己另找途径来设计静态构造函数了.不过Objective-C中又…
