我正在尝试将一些库导入到今天扩展中(在主应用程序中正常工作)。当我运行应用程序时,出现以下错误:
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_Budget", referenced from:
objc-class-ref in TodayViewController.o
"_OBJC_CLASS_$_JBBarChartView", referenced from:
objc-class-ref in TodayViewController.o
"_OBJC_CLASS_$_Users", referenced from:
objc-class-ref in TodayViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
以下是导入内容:
#import "JBBarChartView.h"
#import "JBChartView.h"
#import "Users.h"
#import "Budget.h"
有什么建议吗?
