C# unmanaged function pointers for iOS Just a reminder to myself when I need this thing next time for making Unity work with native code: delegate method should be static to please AOT compiler required for iOS method should have have [MonoPInvokeCal…

Previous works do not relate to function pointers, but reading some documents reading and learning STL functions lets me know the pointer of functions is broadly used in functions such as XXX_if(). I don't think it's really that difficult, but it rea…

函数:一段具有某些特定功能的代码段. 使用函数的严格规定: 1.函数声明 2.函数定义 3.函数调用 函数声明:告知系统编译器该系统的函数名,函数参数,参数类型,参数个数,参数顺序等等,以便函数调用时对其进行校验. 格式:函数返回值类型修饰符  函数名(参数); 一般推荐复制 声明一般放在.h文件中 函数定义: 也叫函数的实现,也就是函数的功能代码 格式: 函数返回值类型修饰符 函数名(参数){ 代码实现.... } 定义一般放在.m文件中 如果定义在了main上边,则可以省略函数声明,如果定义…

Since applications on the iPhone using Xamarin.iOS are compiled to static code, it is not possible to use any facilities that require code generation at runtime. These are the Xamarin.iOS limitations compared to desktop Mono: Limited Generics Support…

from apple In general, iOS adheres to the generic ABI specified by ARM for the ARM64 architecture. However there are some choices to be made within that framework, and some divergences from it. This document describes these issues. Choices Made Withi…

1. Introduction. 1.1 Managed structures that contain strings are a common sight. The trouble is that managed strings are non-blittable. This means that they do not have a single common representation in the unmanaged world. However, there are several…

iOS 4 introduces one new feature that will fundamentally change the way you program in general: blocks. Blocks are an extension to the C language and thus fully supported in Objective-C. If you're coming from a programming language such as Ruby, Pyth…
