經典錯誤：symbol(s) not found for architecture x86_64 || Undefined symbols for architecture x86_64:

記錄經典，防止踩坑！！！！！

 

真機可以運行，模擬器報錯。

錯誤信息顯示如下：

網上查了好多文章，大部分說是路徑問題

像

1.項目中含有靜態庫

可能是該靜態庫不支持在模擬器下編譯,可使用真機或Generic iOS Device,一般就不會出現這個錯誤了;

2.缺少文件引用

從錯誤信息的""_OBJC_CLASS_$_FMDataBase",referenced from:"能夠看出,是缺少FMDataBase文件的引用;

解決方法:

在Build Phases-->Compile Sources(items)中,添加報錯的.m文件,點左下角的"+",在彈出框中找到報錯的.m文件,選中,add
 

這種之類的

 

解決辦法：

在自制的G42PayBucket.framework中，TARGET--》BuildSetting--》Valid Architectures中添加x86_64;如下圖所示。

具體原因，真機arm格式，模擬器x87格式，所以G42PayBucket.framework不支持。添加x86_64格式就行。
