有位网友反馈自己负责的一款多种语言(objective-c/Swift/kotlin)混编的 APP 深受崩溃日志栈帧丢失的困扰。 如下所示: 第一张图是通过 Xcode 看到的相对”真实“的 Backtrace(函数调用栈) 第二张图是通过崩溃获取工具获得的 Backtrace(函数调用栈) 通过对比两张截图,我们很容易发现,第二份崩溃日志的 Backtrace(函数...
Objective-C在C语言的基础上添加了面向对象特性。使用“消息结构”(message structure)而非“函数调用”(function calling)。OC由Smalltalk演化而来,后者是消息型语言的鼻祖。 消息与函数调用的关键区别在于:使用消息结构的语言,其运行时所应执行的代码有运行环境来决定;而使用函数调用的语言,则有编译器决定。

The typeless API is similar to BinaryFormatter, as it will embed type information into the blobs, so no types need to be specified explicitly when calling the API.object mc = new Sandbox.MyClass() { Age = 10, FirstName = "hoge", LastName = "huga" }; // Serialize with the type...
