当我编译我的项目时,我有这个错误:
ld: duplicate symbol _OBJC_CLASS_$_DNCloseButton in /Users/.../Library/Developer/Xcode/DerivedData/...Objects-normal/i386/DNCloseButton-7045D069F03DAA13.o for architecture i386
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/clang++ failed with exit code 1
我知道问题出在课堂上DNCloseButton
,但我不知道如何解决?谢谢你的回答。
