Running a JavaScript function from a website on an iOS device

Currently working on an iOS app that pulls in content from a website. Users can vote for this content by clicking a link on the webpage, which triggers a JavaScript function.

I'm interested in incorporating voting functionality directly into my app without redirecting users to the webpage and prompting them to click on the vote button.

I am aware of the method to execute a JavaScript function from a UIWebView using:

[myWebView stringByEvaluatingJavaScriptFromString:@"myJSFunction()"]

However, I find loading a UIWebView to be a lengthy process, especially for something as simple as casting a vote. Is there a more streamlined approach to calling the JavaScript function without needing user interaction (aside from tapping the vote button within the app)?

Appreciate any advice!

Answer №1

In the realm of iOS, this particular function stands as the sole method to execute a JavaScript function.

Are you referring to utilizing a native user interface to input voting information, with the actual processing being handled by JavaScript?

The necessity of waiting for the UIWebView to complete its operations before triggering stringByEvaluatingJavaScriptFromString may vary based on the actions performed by the JavaScript code, such as DOM interactions. If the JavaScript is ready for immediate use, you might be able to call stringByEvaluatingJavaScriptFromString without having to wait for webViewDidFinishLoad to be called first.
