我有一個自定義類，它是UIControl的子類。接口生成器文件中的未知類MHRotaryKnob
不幸的是我不能夠將代碼編譯由於以下錯誤：
Unknown class MHRotaryKnob in Interface Builder file.
- 我試圖添加
MHRotaryKnob.m在Build Phases -> Compile Sources我只是得到了一堆錯誤：
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_CAKeyframeAnimation", referenced from: objc-class-ref in MHRotaryKnob.o "_OBJC_CLASS_$_CAMediaTimingFunction", referenced from: objc-class-ref in MHRotaryKnob.o "_kCAMediaTimingFunctionEaseIn", referenced from: -[MHRotaryKnob valueDidChangeFrom:to:animated:] in MHRotaryKnob.o "_kCAMediaTimingFunctionEaseOut", referenced from: -[MHRotaryKnob valueDidChangeFrom:to:animated:] in MHRotaryKnob.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)
- 我試圖清理和重建
- 我已經sweeped內容從我的模擬器
我從我的體型搜索關於此特定錯誤的因缺少的資源文件假設相。
在此先感謝。
