iOS controller to display images (URL or UIImage) alongside a strip of thumbnails

Installation

Manual

• Drag DKImageBrowser/DKImageBrowser to your project.
• #import "DKImageBrowser.h" (or #import "DKModalImageBrowser.h")

CocoaPods

platform :ios, '9.0'
pod 'DKImageBrowser'

Usage

Set up the data source array and pass it to an instance of DKImageBrowser.

    DKImageBrowser *imageBrowser = [[DKImageStripController alloc] init];
    imageBrowser.DKImageDataSource =  @[ @"http://placekitten.com/230/400",
                                  	     @"http://placekitten.com/240/400"], ];
    [self.navigationController pushViewController:imagesController animated:YES];

The data source DKImageDataSource can also be a list of UIImage objects.

    imageBrowser.DKImageDataSource = @[ [UIImage imageNamed:@"400-1.jpg"],
                                        [UIImage imageNamed:@"400-2.jpg"], ];

To present the controller modally, use DKModalImageBrowser.

    DKModalImageBrowser *modalImageBrowser = [[DKModalImageBrowser alloc] init];    
    // note: use modalImageBrowser.imageBrowser to set data source, customize
    modalImageBrowser.imageBrowser.DKImageDataSource = @[ [UIImage imageNamed:@"400-1.jpg"],
                                                          [UIImage imageNamed:@"400-2.jpg"], ];
    [self presentViewController:modalImageBrowser animated:YES completion:nil];

Swift

 	func actionDefault() {
        let imageBrowser = DKImageBrowser()
        imageBrowser.title = "UIImage Data Source"
        
        let imageDataSource: [UIImage] = [
            UIImage(named: "400-1.jpg")!,
            UIImage(named: "400-2.jpg")!,
        ]
        imageBrowser.DKImageDataSource = imageDataSource
        
        self.navigationController?.pushViewController(imageBrowser, animated: true)
    }
    
    func actionCustom() {
        var kittenDataSource: [NSString] = []
        let imageHeight = 416
        let imageWidth = Int(self.view.bounds.size.width - 20)
        
        for index in 1...10 {
            let placeKitten = "http://placekitten.com/\(imageWidth + (index * 2  + 10))/\(imageHeight)" as NSString
            kittenDataSource.append(placeKitten)
        }
        
        let modalImageBrowser = DKModalImageBrowser()
        modalImageBrowser.title = "URL Data Source"
        
        modalImageBrowser.imageBrowser.DKImageDataSource = kittenDataSource
        modalImageBrowser.imageBrowser.DKImagePadding = 5
        modalImageBrowser.imageBrowser.DKThumbnailStripHeight = 110
        modalImageBrowser.imageBrowser.DKBackgroundColor = UIColor.blackColor()
        modalImageBrowser.imageBrowser.DKThumbnailStripPosition = 0
        modalImageBrowser.imageBrowser.DKStartIndex = 2
        
        self.presentViewController(modalImageBrowser, animated: true, completion: nil)
    }
