Use Friends League to locate the crash location of the iOS online version project

Introduction

When our project is packaged and uploaded to the Apple Store, the crash problem does not seem so obvious in Xcode, so we have to analyze the crash log of the project so that the collapse analysis of the allies is reflected.

Premise

• Your project is integrated with the Friends League
• Can get the dSYM file to the project

What is a DSYM file

After Xcode compiles the project, we will see a DSYM file with the same name, DSYM is a transit file that holds the address mapping information of the 16 binary functions, the symbols we debug will be included in this file, and a new DSYM file will be generated each time the project is compiled, located in/users /< User name >/library/developer/xcode/archives directory, for each release we are very necessary to save the corresponding Archives file (automatically save the DSYM files This article describes the automatic saving of DSYM files after each compilation by the script.

What is the role of the DSYM file

When our software release mode is packaged or online, it will not be as intuitive as we are in Xcode to see the crash error, this time we need to analyze the crash report file, the IOS device will have a log file to save each of our application error function memory address, through Xcode Organizer can export the IOS device Devicelog to crash file, this time we can use the wrong function address to query the DSYM file of the program corresponding function name and file name. The premise is that we need to have a software version corresponding to the DSYM file, which is why it is necessary for us to save each release version of the Archives file.

how to get the dSYM file for a project

Archieves, Organization, Window, Xcode

Once the dSYM file is downloaded, the corresponding file is found directly in the show in finder

Of course, if the project package at that time is not the same way that you submit AppStore, the person who packaged the same method provides the dSYM file.

So far, the dSYM file is ready.
