Reflection effect based on IOS

This example shares the specific code of IOS to realize the reflection effect for your reference. The specific contents are as follows

1、 Brief description

We can duplicate layers, create a duplicate layer, and then rotate it to add the corresponding color difference. The effect can be achieved
When creating the interface, our view uses vcview

2、 Code

2.1 VCView.m

//
// VCView.m
// 03_ UIView76_ inverted reflection in water

#import "VCView.h"

@implementation VCView

+(Class)layerClass{
  return [CAReplicatorLayer class];
}
@end

2.2 ViewController.m

//
// ViewController.m
// 03_ UIView76_ inverted reflection in water
//

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  //Get the copy layer and copy the sub layer (the view here is vcview)
  CAReplicatorLayer * repL = (CAReplicatorLayer*)self.view.layer;
  repL.instanceCount = 2;

  //Rotate 180 degrees PI about the X axis
  repL.instanceTransform = CATransform3DMakeRotation(M_PI, 1, 0, 0);

  repL.instanceRedOffset -= 0.1;
  repL.instanceGreenOffset -= 0.1;
  repL.instanceBlueOffset -=0.1;
  repL.instanceAlphaOffset -= 0.1;

}

@end
