Re: how to pass large data to UIWebView javascript from Objective-C

First up, if you’re using UIWebView you should consider making the switch to WKWebView; it’s the future of web views on our platforms.
Second, define “large” in this context? Hundreds of KiB? MiB? Tens of MiB?

Thanks for your information.
The size of html content that needs to be passed from obj-c to js is around 40KB.

Oh wow, much smaller than I expected. At that size I’d just wrap the HTML in a JavaScript string and pass that in to the web view via
-stringByEvaluatingJavaScriptFromString:.Share and Enjoy

I've tried in the following way to send NSString variable conte to pass to the javascript function otverse(t)
Length of conte : 4223
in objective-c
NSString *fun = [NSString stringWithFormat:@"otverse(['%@'])",conte];
[self.webView stringByEvaluatingJavaScriptFromString:fun];
in javascript from html file
function otverse(t)
{
alert("Result from obj-c " + t);
}
But the function otverse is not called.

Further if i call the javascript function otverse with small string, it is invoked.
Could you help me to pass string of length more than 1000 to javascript from obj-c.
Thanks in advance.
