PCH files can provide some convenience for our programming. is a header file that can be shared and accessed by all other source files in the project, and is suitable for placing global macro definitions and header files.Since Xcode6, the PCH file created by default has been removed, to reduce build time and also to lose convenienceXcode6 How to add a PCH header

PCH file for iOS learning,1. Overview of PCH files A pch file is a pre-compiled header file (generally with the extension. PCH) That precompiles stable code in a project and stores it in a file (. PCH. These pre-compiled codes can be any C/C ++ code-or even inline function

I. INTRODUCTIONFirst the PCH file (ie: Prefix Header) is a precompiled file that is created automatically by creating a new project before Xcode 6, but after Xcode 6, Apple officially changes the way it is automatically created to manual manually created later;This file is primarily used in project engineering to store the more common and stable classes in which the method resources are shared at development time, without having to refer to their head

IOS. pch When we create a new project, we will see a Prefix in the Supporting FIles file. the file ending with pch. pch is the "precompiled header", that is, the pre-compiled header file. Some codes that are not frequently modified in the project stored in the file, such as common framework header files, this aims to increase the compilation speed of the compiler

Select PCH file in other under the IOS template. 3. When naming the PCH file, I chose the same naming method as xcode5, where analyzerhd is my project name. Note that I

Before Xcode6, when a new project is created, the system will automatically create a PCH (precompile header) file with the name of the project, and during the development process, the header files that are widely used throughout the project can be included in the file. The compiler will automatically add the header files in the PCH file to all the source files, so that you can use the contents of the header
