    [webView stringByEvaluatingJavaScriptFromString:@"your script"];

    stringByEvaluatingJavaScriptFromString:

    Returns the result of running a script.
    – (NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)script Parameters

    script

    The script to run.

    Return Value

    The result of running script or nil if it fails.

    Discussion

    JavaScript execution time is limited to 10 seconds for each top-level
    entry point. If your script executes for more than 10 seconds, the web
    view stops executing the script. This is likely to occur at a random
    place in your code, so unintended consequences may result. This limit
    is imposed because JavaScript execution may cause the main thread to
    block, so when scripts are running, the user is not able to interact
    with the webpage.

    JavaScript allocations are also limited to 10 MB. The web view raises
    an exception if you exceed this limit on the total memory allocation
    for JavaScript. Availability

    Available in iOS 2.0 and later.
