PicoAWSECommerceServiceClient

Pico Objective-C Client for the Amazon Product Advertising API

Note

This is only the proxy part of the PicoAWSECommerceServiceClient, you need to integrate with Pico Runtime before you can use this proxy, please follow instructions on Pico github site to add the Pico runtime library and the PicoAWSECommerceServiceClient in your iOS app, you may also start with the sample mentioned in Reference Sample section below.
You need to fill in AWSAccessKeyId and AWSSecureKeyId in AWSECommerceServiceClient before your app can invoke Amazon Product Advertising service, and you must call - (void)authenticateRequest:(NSString *)action method in the AWSECommerceServiceClient to authenticate the request everytime you make a service call, see sample mentioned in Reference Sample section for details.
Besides proxy code, this site also hosts the appledoc for the PicoAWSECommerceServiceClient.

As per Amazon:

You will not, without our express prior written approval, use any Product Advertising Content on or in connection with any site or application designed or intended for use with a mobile phone or other handheld device.

So please consult Amazon for permission before you can use its Product Advertising Content on any iOS devices.

##Example Usage With this proxy and the generic Pico runtime library, Amazon Product Advertising API invocation on iOS platform is quite simple:


        // start progress activity
        [self.view makeToastActivity];
        
        // get shared client
        AWSECommerceServiceClient *client = [AWSECommerceServiceClient sharedClient];
        client.debug = YES;
        
        // build request, see details here:
        ItemSearch *request = [[[ItemSearch alloc] init] autorelease];
        request.associateTag = @"tag"; // seems any tag is ok
        request.shared = [[[ItemSearchRequest alloc] init] autorelease];
        request.shared.searchIndex = @"Books";
        request.shared.responseGroup = [NSMutableArray arrayWithObjects:@"Images", @"Small", nil];
        ItemSearchRequest *itemSearchRequest = [[[ItemSearchRequest alloc] init] autorelease];
        itemSearchRequest.title = _searchText.text;
        request.request = [NSMutableArray arrayWithObject:itemSearchRequest];
        
        // authenticate the request
        // http://docs.aws.amazon.com/AWSECommerceService/latest/DG/NotUsingWSSecurity.html
        [client authenticateRequest:@"ItemSearch"];
        [client itemSearch:request success:^(ItemSearchResponse *responseObject) {
            // stop progress activity
            [self.view hideToastActivity];
            
            // success handling logic
            if (responseObject.items.count > 0) {
                Items *items = [responseObject.items objectAtIndex:0];
                if (items.item.count > 0) {
                    Item *item = [items.item objectAtIndex:0];
                    
                    // start image downloading progress activity
                    [self.view makeToastActivity];
                    // get gallery image
                    NSURL *imageURL = [NSURL URLWithString:item.smallImage.url];
                    NSData *imageData = [NSData dataWithContentsOfURL:imageURL];
                    // stop progress activity
                    [self.view hideToastActivity];
                    
                    UIImage *image = [UIImage imageWithData:imageData];
                    [self.view makeToast:item.itemAttributes.title duration:3.0 position:@"center" title:@"Success" image:image];
                } else {
                    // no result
                    [self.view makeToast:@"No result" duration:3.0 position:@"center"];
                }
                
            } else {
                // no result
                [self.view makeToast:@"No result" duration:3.0 position:@"center"];
            }
        } failure:^(NSError *error, id<PicoBindable> soapFault) {
            // stop progress activity
            [self.view hideToastActivity];
            
            // error handling logic
            if (error) { // http or parsing error
                [self.view makeToast:[error localizedDescription] duration:3.0 position:@"center" title:@"Error"];
            } else if (soapFault) {
                SOAP11Fault *soap11Fault = (SOAP11Fault *)soapFault;
                [self.view makeToast:soap11Fault.faultstring duration:3.0 position:@"center" title:@"SOAP Fault"];
            }
        }];
