UIView *v=[[UIView alloc]initWithFrame:CGRectMake(10, 10, 100, 100)];
v.backgroundColor=[UIColor yellowColor];
//v.layer.masksToBounds=YES;这行去掉
v.layer.cornerRadius=10;
v.layer.shadowColor=[UIColor redColor].CGColor;
v.layer.shadowOffset=CGSizeMake(10, 10);
v.layer.shadowOpacity=0.5;
v.layer.shadowRadius=5;
[self.view addSubview:v];
效果如下

/* When true an implicit mask matching the layer bounds is applied to
- the layer (including the effects of the `cornerRadius' property). If
- both
mask' andmasksToBounds' are non-nil the two masks are - multiplied to get the actual mask values. Defaults to NO.
- Animatable. */
