添加第三方类库造成的Undefined symbols for architecture i386:编译错误

在使用下拉刷新类库EGORefreshTableHeaderView的时候，将资源文件添加到工程中，但是忘记假如QuartzCore.framework框架，造成编译错误：
Undefined symbols for architecture i386: "_CATransform3DMakeRotation", referenced from: -[EGORefreshTableHeaderView setState:] in EGORefreshTableHeaderView-6F75314CE1079327.o "_OBJC_CLASS_$_CALayer", referenced from: objc-class-ref in EGORefreshTableHeaderView-6F75314CE1079327.o "_OBJC_CLASS_$_CATransaction", referenced from: objc-class-ref in EGORefreshTableHeaderView-6F75314CE1079327.o "_CATransform3DIdentity", referenced from: -[EGORefreshTableHeaderView setState:] in EGORefreshTableHeaderView-6F75314CE1079327.o "_kCAGravityResizeAspect", referenced from: -[EGORefreshTableHeaderView initWithFrame:arrowImageName:textColor:] in EGORefreshTableHeaderView-6F75314CE1079327.o "_kCATransactionDisableActions", referenced from: -[EGORefreshTableHeaderView setState:] in EGORefreshTableHeaderView-6F75314CE1079327.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)



解决方法：targets——>build phases——>link binary with libraries——>QuartzCore.framework

当添加其他类库的时候也可能因为没有添加framework或者是它们依赖的库同样也会出现这样错误。
