Detailed Description

Core and external libraries necessary for the fuzzer functionality.

This section includes the necessary headers for the Foundation framework, UIKit, Core Graphics, standard input/output, standard library, memory management, mathematical functions, Boolean type, floating-point limits, and string functions. These libraries support image processing, UI interaction, and basic C operations essential for the application.

Method Documentation

collectionView:cellForItemAtIndexPath:

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

implementation

Asks the data source for the cell that corresponds to the specified item in the collection view.

Parameters

collectionView	The collection view requesting this cell.
indexPath	The index path that specifies the location of the item.

Returns

A configured cell object.

Definition at line 46 of file ViewController.m.

                                        :(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"ImageCell" forIndexPath:indexPath];
    
    // Configure cell
    cell.backgroundColor = [UIColor lightGrayColor]; // For visibility
    
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:cell.contentView.bounds];
    imageView.contentMode = UIViewContentModeScaleAspectFit;
    imageView.image = self.fuzzedImages[indexPath.row];
    [cell.contentView addSubview:imageView]; // Add imageView to cell's contentView
    
    NSLog(@"Configuring cell for item at %@ with image name: %@", indexPath, self.imagePaths[indexPath.row]);
    
    return cell;
}

Here is the call graph for this function:

collectionView:layout:sizeForItemAtIndexPath:

- (CGSize) collectionView: (UICollectionView *) collectionView layout: (UICollectionViewLayout *) collectionViewLayout sizeForItemAtIndexPath: (NSIndexPath *) indexPath

implementation

Asks the delegate for the size of the specified item’s cell.

Parameters

collectionView	The collection view object displaying the flow layout.
collectionViewLayout	The layout object requesting the information.
indexPath	The index path of the item.

Returns

The width and height of the specified item. Adjust as needed.

Definition at line 46 of file ViewController.m.

                        :(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
    return CGSizeMake(100, 100); // Adjust size as needed
}

collectionView:numberOfItemsInSection:

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

implementation

Asks the data source for the number of items in the specified section.

Returns the number of fuzzed images.

Parameters

collectionView	The collection view requesting this information.
section	The index number of the section.

Returns

The number of rows in section.

Definition at line 46 of file ViewController.m.

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

}

loadFuzzedImagesFromDocumentsDirectory

- (void) loadFuzzedImagesFromDocumentsDirectory

implementation

Loads fuzzed images from the documents directory into the collection view.

viewDidLoad

- (void) viewDidLoad

implementation

Called after the controller's view is loaded into memory.

Initializes the view controller's properties, collection view, and loads fuzzed images.
