Examples

The following are code samples to illustrate how to integrate Pop-up Store in mobile applications.

Note: All Objective-C examples are using Automatic Reference Counting (ARC) and do not include any explicit memory deallocation calls.

API Examples are using All Seeing Interactive's ASIHTTPRequest, a commonly used HTTP request framework, and John Engelhart's JSONKit for JSON parsing.

Push API - Preview Image

	- (void)sendPreviewImage:(NSData *)previewImage
	{
	__unsafe_unretained __block ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"https://store.canvaspop.com/api/push/preview"]];

	[request setDefaultResponseEncoding:NSUTF8StringEncoding];

	// Include auth headers
	[request addRequestHeader:@"CP-Authorization" value:@"basic"];
	[request addRequestHeader:@"CP-ApiKey" value:@"YOUR_API_KEY"];

	// Load the image
	[request addData:previewImage withFileName:@"previewImage" andContentType:@"image/jpeg" forKey:@"photo"];

	[request setCompletionBlock:^{

	int responseCode = [request responseStatusCode];

	if(responseCode == 200) {

	// Parse the image token from the response
	NSString *responseString = [request responseString];
	NSDictionary *responseDictionary = [responseString objectFromJSONString];
	NSString *token = [responseDictionary valueForKey:@"image_token"];

	NSLog(@"Preview image uploaded successfully, received token: %@", token);

	// Open the loader
	[self performSelectorInBackground:@selector(openLoader:) withObject:token];

	}

	else
	{
	NSLog(@"Preview image handshake failed!");
	NSLog(@"HTTP Status code: %d", responseCode);
	}


	}];

	[request setFailedBlock:^{

	NSError *error = [request error];
	NSLog(@"Preview image upload failed!");
	NSLog(@"%@", [error localizedFailureReason]);

	}];

	[request startAsynchronous];
	}

Open Loader

	- (void)openLoader:(NSString *)token
	{

	// Replace with actual print width & height values
	int printImageWidth = 2500;
	int printImageHeight = 2500;

	NSString *urlAddress = [NSString stringWithFormat:@"https://store.canvaspop.com/loader/%@/%i/%i", token, printImageWidth, printImageHeight];

	//Create a URL object.
	NSURL *url = [NSURL URLWithString:urlAddress];

	//URL Requst Object
	NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

	//Load the request in the UIWebView.
	[self.storeWebView loadRequest:requestObj];
	}

Push API - Print Image

	// Include auth headers

	// Include the preview image token
	[request addPostValue:[self previewImageToken] forKey:@"token"];

	// Include the image
	[request addData:printImage withFileName:@"printImage" andContentType:@"image/jpeg" forKey:@"photo"];

	[request setCompletionBlock:^{

	int responseCode = [request responseStatusCode];

	if(responseCode == 200) {

	// Parse the message from the response
	NSString *responseString = [request responseString];
	NSDictionary *responseDictionary = [responseString objectFromJSONString];
	NSString *message = [responseDictionary valueForKey:@"message"];

	NSLog(@"Print image upload completed successfully");
	NSLog(@"Message: %@", message);
	}

	else

PopUpStore Event handling
