Our Photo Printing API is a great way for app developers, brands, and website owners to monetize their visual content and make it easy for their customers to turn their images into beautiful canvas prints.

The iOS library helps you integrate our Photo Printing API in less than half an hour! Follow the instructions provided below to integrate the library within your iOS application. The library is universal and works on both iPhone and iPad devices.

Once a print is purchased within your application, our designers can turn any image into a big beautiful canvas. We print, package, and ship all orders with love directly to your customers.


Current version: 1.0.7 (download)

Installation via Cocoapods

Installing the library is simple and should only take a few minutes. This may be done manually or via cocoapods.

Add the following to your Podfile:

pod 'PopUpLib'

Run pod install

This will give you all of the necessary files to begin integrating our photo printing API. For next steps, see the section on ‘Integration’ below.

Manual Installation

Installing PopUpLibLib.framework is simple.

  1. Download the repo from github

  2. Drag PopUpLib.bundle and PopUpLib.framework into your project.


  3. In the Build Phases tab of your app’s Target, under the "Link Binary With Libraries" section, hit the add button and add: MobileCoreServices.framework, CFNetwork.framework, SystemConfiguration.framework, libz.dylib


  4. If you are supporting iOS 9 or later, in your app’s Info.plist file, add the following:

This ensures the library is able to display all web assets correctly when App Transport Security behaviours are in place. For more on App Transport Security in iOS 9 see here.

Integrating the CanvasPop iOS library into your app is very simple.

There are two main files included with the framework.

File Description
PopUpLib.h The file you include in your project i.e. #import <PopUpLib/PopUpLib.h>
PopUpStoreController.h The view controller you will need to initiate and present
  1. Choose where your users will launch the Pop-up Store Controller. Inside the header file for your controller, add #import <PopUpLib/PopUpLib.h> and implement the PopupStoreControllerDelegate protocol:
    @interface ViewController : UIViewController <PopupStoreControllerDelegate> {
  2. At the desired time (e.g. tapping a button, after taking/editing a photo), instantiate a PopupStoreController. If one was created successfully (i.e. the call did not return nil), present the Pop-up Store controller.


    • image – the image that will be printed on canvas
    • applicationKey – your partner API key
    • delegate – Any class that implements the PopupStoreControllerDelegate protocol (usually self)
    PopupStoreController *controller =  [[PopupStoreController alloc] 
                                        initWithImage:[UIImage imageNamed:@"your_descired_image.jpg"] 
    if (controller) {
        [self presentViewController:controller animated:YES completion:NULL];

    Status Bar

    The iOS library now provides support to show or hide the status when using PopupStoreController. By default the library will hide the status bar. If you wish to use this option you may set it with a bool value using the setLibShouldShowStatusBar method shown below.

    PopupStoreController *popUpStoreController = [[PopupStoreController alloc] initWithImage:[UIImage imageNamed:@"your_descired_image.jpg"] applicationKey:YOUR_PARTNER_KEY delegate:self];
    [popUpStoreController setLibShouldShowStatusBar:<STATUS_BAR_PREFERENCE>];
    [self presentViewController:popUpStoreController animated:YES completion:NULL];
  3. Implement the PopupStoreControllerDelegate protocol. There are currently six delegate methods; one that is required and five that may be optionally implemented. They are as follows:


    - (void)popupStoreLibWasClosed:(PopupStoreController *)lib
        * Here a user has closed the Pop-up Store controller and it must be dismissed
        [self dismissViewControllerAnimated:YES completion:nil];


    The following methods are optional and may be implemented to receive callbacks.

    - (void)popupStoreLibWasOpened:(PopupStoreController *)lib
        * Here a user has opened the Pop-up Store controller successfully
        NSLog(@"Pop-up Store lib was opened");
    - (void)popupStoreLibUserTappedContinue:(PopupStoreController *)lib
        * Here a user has tapped the continue button after the initial image handshake was completed
        * The user will then be taken to the store with their desired image
        NSLog(@"Pop-up Store user tapped continue");
    - (void)popupStoreWasLoadedWithImage:(PopupStoreController *)lib
        * Here the web request to load Pop-up Store with a users image completed successfully
        * A user is presented with a cart containing their image and print options
        NSLog(@"Pop-up Store cart page loaded successfully with image");
    - (void)popupStoreLibPrintHandshakeCompleted:(PopupStoreController *)lib
        * The library implements a two-step handshake documented here:
        * Here the high resolution, printable version of the desired image was uploaded succesfully
        NSLog(@"Pop-up Store print image handshake completed");
    - (void)popupStoreEventWasEmitted:(PopupStoreController *)controller withEvent:(NSString*)eventName withPayload:(NSDictionary *)payload
        * Here a user has interacted with Pop-up Store and an HTML5 pushMessage() was emitted.
        * Depending on the event, it may have an associated payload value sent along with the event name.
        * For further details emitted events and their payloads see here: 
        NSLog(@"PopupStore event was emitted with payload");
        NSLog(@"Event: %@", eventName);
            NSLog(@"Payload: %@", payload);


We’re always happy to help out with code or any other questions you might have.
It’s important to us that you are able to get PopUp Store integrated into your application as quickly and smoothly as possible.
