记录经典，防止踩坑！！！！！

 

真机可以运行，模拟器报错。

错误信息显示如下：

网上查了好多文章，大部分说是路径问题

像

1.项目中含有静态库

可能是该静态库不支持在模拟器下编译,可使用真机或Generic iOS Device,一般就不会出现这个错误了;

2.缺少文件引用

从错误信息的""_OBJC_CLASS_$_FMDataBase",referenced from:"能够看出,是缺少FMDataBase文件的引用;

解决方法:

在Build Phases-->Compile Sources(items)中,添加报错的.m文件,点左下角的"+",在弹出框中找到报错的.m文件,选中,add
 

这种之类的

 

解决办法：

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

具体原因，真机arm格式，模拟器x87格式，所以G42PayBucket.framework不支持。添加x86_64格式就行。
