我正在尝试在应用程序购买中实现,我遵循了这个很棒的教程In-App Purchases 简介
当我清理项目时,它没有显示任何错误,但是当我构建项目时,它给了我这些错误:
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_MBProgressHUD", referenced from:
objc-class-ref in PDF_Product.o
"_OBJC_CLASS_$_Reachability", referenced from:
objc-class-ref in PDF_Product.o
"_OBJC_CLASS_$_InAppRageIAPHelper", referenced from:
objc-class-ref in AppDelegate.o
objc-class-ref in PDF_Product.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
我试图删除文件并再次添加它们,但没有奏效。有什么想法吗?
