Select Demo on the iOS 3D effect page

The home page of the project needs a 3D effect. You can refer to this Demo. What about this example? I got one from the Internet, but I don't know. It's amazing that the people who wrote the Demo can do it easily. It's amazing, I watched it for an hour. It is easy to understand here, at least I think it is easy to understand.

 

In the Framework class example.

ViewController. h

 

#import 
 
  #import FlowCoverView.h@interface ViewController : UIViewController
  
   @property (strong , nonatomic) FlowCoverView* m_FlowCoverView;@end
  
 

ViewController. m

 

 

// Obtain the screen height # define ScreenHeight [[UIScreen mainScreen] bounds]. size. height // obtain the screen width # define ScreenWidth [[UIScreen mainScreen] bounds]. size. width # import ViewController. h @ interface ViewController () @ end @ implementation ViewController-(void) viewDidLoad {[super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. self. m_FlowCoverView = [[FlowCoverView alloc] initWithFrame: CGRectMake (0, 0, ScreenWidth, ScreenHeight)]; self. m_FlowCoverView.delegate = self; [self. view addSubview: self. m_FlowCoverView];}-(int) flowCoverNumberImages :( FlowCoverView *) view {return 6;}-(UIImage *) flowCover :( FlowCoverView *) view cover :( int) image {switch (image % 6) {case 0: default: return [UIImage imageNamed: @changmen.jpg]; case 1: return [UIImage imageNamed: @changmen.jpg]; case 2: return [UIImage imageNamed: @changmen.jpg]; case 3: return [UIImage imageNamed: @changmen.jpg]; case 4: return [UIImage imageNamed: @changmen.jpg]; case 5: return [UIImage imageNamed: @ changmen.jpg] ;}}- (void) flowCover :( FlowCoverView *) view didSelect :( int) image {NSLog (@ Selected Index % d, image );}
