First, create the PCH file. Click Command+n. such as OperationNaming conventions are generally: project name-prefixStep TwoOK, you have finished making the PCH file here. Then you can use it.PCH files generally write data that can be used globally.Like what:The width and color of the screen (no punctuation behind the macro)#define RGB (r,g,b,a) [Uicolor colorwithred: (r/255.0) Green: (g/255.0) Blue: (b/25

NSLog function is not shielded, will inevitably result in memory consumption, performance weakening, This is a good app for the starting point is very inconsistent, so in the real machine with PCH set global variables do not print NSLog function is an essential requirement in the actual combat project.The implementation method is as follows:Select the PCH file (

The PCH file and NSLog real machine are not printed during iOS development.Add a PCH File Now, when creating a new project in Xcode6 and 7, the PCH file is no longer included by default. You need to manually add the PCH file.Under the Supporting Files directory, select File>

Swift reads app version information There is time we need to read the app version information such as configuration information, so we can use the method: Nsbundle.mainbundle (). Infodictionary to get Example:SwiftLet infodictionary = Nsbundle.mainbundle (). infodictionaryLet shortversion = infodictionary! ["Cfbundleshortversionstring"]Print (shortversion!)PCH

1. pch File overview PCH file is a precompiled header file (a generic extension of. PCH) is a project in which the more stable code is pre-compiled and placed in a file (. PCH). These pre-compiled code can be any C/s code--or even an inline function--that is more stable throughout the project, i.e. code that i
