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];
