iOS 设置View阴影效果

本文通过实例代码给大家讲解了iOS 设置View阴影效果，代码简单易懂非常不错，具有一定的参考借鉴价值,需要的朋友可以参考下

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];
