增加指定bundle接口

[jt042435]

对外提供静态库和bundle，不能获取bundle里面的xib，怎么解决？能不能指定bundle？

• (UINib *)nib { return [UINib nibWithNibName:self.nibid bundle:[self XXNibBundle]]; }
• (NSBundle *)XXNibBundle { if ([[self class] respondsToSelector:@selector(nibBundle)]) { return [[self class] performSelector:@selector(nibBundle)]; } return nil; }
