How to display more than 10 results from Walmart API in iOS?

I’m working on an iOS app that uses the Walmart Search API to show product listings. The API has a limit of 25 items per page, but I’m only getting 10 results in my app. Here’s a snippet of the JSON response:

{
  "query": "smartphone",
  "totalResults": 2500,
  "start": 1,
  "numItems": 10,
  "items": [
    {
      "productId": "ABC123",
      "productName": "Latest Smartphone Model",
      "price": 599.99
    }
  ]
}

I want to load more items when the user scrolls through the table view. How can I adjust the ‘start’ parameter to fetch the next set of results? Also, any tips on implementing infinite scrolling with this API would be really helpful. Thanks!

To display more than 10 results from the Walmart API in iOS, you’ll need to modify your API request parameters. The ‘numItems’ parameter controls how many items are returned per request, so increase it to 25 (the maximum allowed). Also, use the ‘start’ parameter to paginate through results.

For infinite scrolling, implement UITableViewDataSourcePrefetching. When the user nears the end of the current results, trigger a new API call with an updated ‘start’ value. For example, if you’ve loaded 25 items, set ‘start’ to 26 for the next request.

Keep track of the total results and stop making requests when you’ve fetched all available items. Remember to handle errors and network issues gracefully. Consider using a third-party library like SDWebImage for efficient image loading in your table view cells.

I’ve dealt with similar API pagination issues before, and here’s what worked for me:

First, make sure you’re setting the ‘numItems’ parameter to 25 in your API request. That’ll give you the max results per call.

For infinite scrolling, I implemented a simple solution using UIScrollViewDelegate. In scrollViewDidScroll, I check if the user is near the bottom of the table view. If they are, I trigger the next API call with an updated ‘start’ value.

To calculate the ‘start’ value, I keep track of the total items loaded so far. So if I’ve loaded 50 items, the next ‘start’ would be 51.

One tip: cache your results locally. It improves the user experience if they scroll back up, and it reduces unnecessary API calls.

Also, don’t forget to handle edge cases like when there are no more results to load. Good luck with your app!

hey there! i’ve worked with walmart api before. for more results, try changing the ‘numItems’ parameter to 25 in ur request. for infinite scrolling, check out UITableViewDataSourcePrefetching. it’s pretty neat! just update the ‘start’ value each time u load more. good luck with ur app!
