Xcodepch

The use of PCH during development is a more efficient option. Xcode is automatically included in this file during the compilation process.

This means that the contents of this file are visible to all of your. m files.

Using this feature I usually do these things in this file:

1 commonly used macros.

2. h files that may need to be frequently included in the development

3 log output Switch control. Output is not required in release version.

I don't quite understand that the PCH was not automatically added to the new project after xcode6.0.

Manual configuration is actually a very simple process.

First AddFiles

Then you need to open the use of the PCH in Buildsettings and configure the path to the PCH file.

You can do it!!
