有的人想到 可以在方法里面直接調用哪個控件用就在哪里調用 ?但是不推薦 因為用到的控件 可能是UILabel蒂萎、UIBUtton、UIView等 而且為了 貼近系統(tǒng)屬性設置的特點 ? 最好是給UIView加分類
使用 （注意震嫉，由于基于Layer?控件的背景色用我提供的dj_backgroundColor）
? ? UIView *view = [[UIView alloc]initWithFrame:CGRectMake(100, 100, 160, 100)];
? ? view.dj_backgroundColor = [UIColor redColor];
? ? view.dj_shadowColor? ? = [UIColorblackColor];
? ? view.dj_shadowOffset? ? =CGSizeMake(0,6);
? ? view.dj_shadowRadius? ? =6;
? ? view.dj_shadowOpacity? =0.6;
? ? view.dj_corners? ? ? ? =UIRectCornerTopLeft | UIRectCornerBottomLeft;
? ? view.dj_radius? ? ? ? ? =25;
? ? [self.viewaddSubview:view];
分類的.h
