NSLog batch processing after release

NSLog must be used in development, but it is especially performance-consuming. Therefore, it must be removed after the product is released.

It is quite difficult to process NSLog in a large development project, so you can consider macro definition in the pch file, such:

# Define MyLog (...) NSLog (_ VA_ARGS __)

You can comment out the NSLog (_ VA_ARGS _) after the program is released. You can also use conditional judgment to avoid repeated comments:

# Ifdef DEBUG

# Define MyLog (...) NSLog (_ VA_ARGS __)

 

# Else

# Define MyLog (...)

# Endif

 

The pch file is included in each header file. Therefore, you cannot put all the files to be imported into the file because of pch, which increases the burden on the system.

It must be confirmed that almost all files in the system are required to be imported in pch.
