带有填充有数组的“集合/表”视图的明细视图？

Question

I'm having a similar problem in two separate instances, but I feel like the solution for one problem will solve the other. I'm a noob. I'm using a Collection View for a photo gallery that I have populated with an NSArray. The collection view works just fine, and populates the right images in the right order. I just can't figure out how to get the detail view to work correctly with the code that I have specifically. I have my delegates set up in the .h file:

@interface PhotoViewController : UICollectionViewController <UICollectionViewDelegate, UICollectionViewDataSource>

The NSArray looks like this:

#import "PhotoViewController.h"
#import "PhotoViewCell.h"
#import "ImageDetailController.h"

@interface PhotoViewController ()

@end

@implementation PhotoViewController {

    NSArray *array;

}

- (void)viewDidLoad {

        array = [[NSArray alloc]initWithObjects:@"walkerthumb.png",@"farmerthumb.png",@"unrulythumb.png",@"fetchthumb.png",@"walkerthumb.png",@"farmerthumb.png",@"unrulythumb.png",@"fetchthumb.png",@"walkerthumb.png",@"farmerthumb.png",@"unrulythumb.png",@"fetchthumb.png",@"walkerthumb.png",@"farmerthumb.png",@"unrulythumb.png",@"fetchthumb.png",@"walkerthumb.png",@"farmerthumb.png",@"unrulythumb.png",@"fetchthumb.png",@"walkerthumb.png",@"farmerthumb.png",@"unrulythumb.png",@"fetchthumb.png", nil];

    [super viewDidLoad];
    // Do any additional setup after loading the view.





}

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {



    PhotoViewCell *cell = (PhotoViewCell*)[collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];

    [[cell myImageView]setImage:[UIImage imageNamed:[array objectAtIndex:indexPath.item]]];

    return cell;





}

-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {

    return [array count];


}

In my cell's header file, I have the image property called out like this:

@property (weak, nonatomic) IBOutlet UIImageView *myImageView;

I'm trying to push a different detail view based on the image clicked. I understand it must involve some sort of array again, but I just don't know how to implement it. I don't know how to tell the Collection View what to do. None of the tutorials I have tried online have worked.

You have to implement the following method to get the click of an item in collection view. - (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath: (NSIndexPath *)indexPath { //indexPath will return the clicked row index and section. }
