iOS 设置View阴影效果

需要设置 颜色 阴影半径 等元素

uiview *shadowview = [[uiview alloc] init];
 shadowview.frame = cgrectmake(100, 100, 100, 100);
 shadowview.center = self.view.center;
 shadowview.backgroundcolor = [uicolor whitecolor];
 //设置阴影颜色
 shadowview.layer.shadowcolor = [uicolor colorwithred:114.0/255.0 green:133.0/255.0 blue:152.0/255.0 alpha:1.0].cgcolor;
 //设置阴影的透明度
 shadowview.layer.shadowopacity = 0.1f;
 //设置阴影的偏移
 shadowview.layer.shadowoffset = cgsizemake(30.0f, 10.0f);
 //设置阴影半径
 shadowview.layer.shadowradius = 15.0f;
 //设置渲染内容被缓存
 shadowview.layer.shouldrasterize = yes;
 //超出父视图部分是否显示
 shadowview.layer.maskstobounds = no;
 shadowview.layer.borderwidth = 0.0;
 shadowview.layer.opaque = 0.10;
 shadowview.layer.cornerradius = 3.0;
 //栅格化处理
 shadowview.layer.rasterizationscale = [[uiscreen mainscreen]scale];
 //正常矩形
 uibezierpath *path = [uibezierpath bezierpathwithrect:shadowview.bounds];
 shadowview.layer.shadowpath = path.cgpath;
 [self.view addsubview:shadowview];
