Shadow effect to View in iOS without affecting the performance

The below method which set the shadow effect to view but it is performance wise lacking when we apply animation to that view

-(void)setShadowEffectWithPerformanceLack{
   
    self.view.layer.masksToBounds=NO;
    self.view.layer.backgroundColor=[UIColor darkGrayColor].CGColor;
    self.view.layer.shadowRadius=12;
    self.view.layer.shadowOffset=CGSizeMake(0, 0);
    self.view.layer.shadowOpacity=0.5;
 }

UIBeizerPath  which is used to avoid the performance lacking. (see Apple's Documentation)

-(void)setShadowEffectUsingUIBeizerPath{

    

    self.view.layer.masksToBounds=NO;

    self.view.layer.backgroundColor=[UIColor darkGrayColor].CGColor;

    self.view.layer.shadowRadius=5;

    self.view.layer.shadowOffset=CGSizeMake(0, 0);

    self.view.layer.shadowOpacity=0.5;

    

    UIBezierPath *path=[UIBezierPath bezierPathWithRoundedRect:self.view.bounds cornerRadius:12];

    [self.view.layer setShadowPath:[path CGPath]];

    

}
