to debug them later. Fortunately, there is a more elegant solution, is to add the following piece of code in the project's prefix.pch file, after joining, NSLog only in the debug output, release under not output.How to achieve: in-prefix.pch (PCH full name is "precompiled Header", that is, the precompiled header file, which is stored in the project some infrequently modified code, such as the usual framework header file, so that the purpose of improv

In xcode6, the new project does not have a PCH file by default. Apple must cancel the PCH file. At the beginning, many people may not be comfortable with it. If we want to use the PCH file, you need to add them manually. The steps are as follows: (directly) @ Reason for cancellation: One person on stackoverflow explained this as follows:I suspect because of mod

Many times, due to the need for development, we often need to define in the PCH some variables that are used throughout the project, etc. In general, during the previous development process, we were accustomed to writing a macro directly in the PCH to get it done. But when we carefully analyze Apple's official documents, we will find that some of the variables defined in him are not defined by macros, b

The first step: command+n create a. pch file, the file name can be setStep Two: Add some globally used macros to the PCH and commonly used afnetworking-like three-party librariesStep three: Open the project's building Setting, search the prefix Header$ (srcroot) refers to the project root directory, after the set up will automatically show the path, after compiling you will find that you can be transferred

The previous PCH for iOS was the system's own, and then Apple canceled the PCH, and I've been disgusted with the addition. I don't know if my brain is smoking recently. It was added. Do not like to add, because I want their code sent to others, other people can run anywhere, without changing the wrong warning.Reflection of a bit, because a lot of people are added, online blog also have a variety of how to a

In general, in the previous development process, we are all used to writing a macro directly in pch.

PCH can be used to store shared information, such as the width and height of a device's screen.
