Question

Is it possible for me to add text to a uiwebview and change the text and colours in this view without having separate html files? So I define whats in the html file in a switch statement? I do this at the moment using labels, but I can’t have more than one colour in a label so I need to use html, as core text looks quite complicated.

switch (counter)
{
    case 0:
        titleLabel.text = @"needs to be more than one colour";
      break;
    case 1:
        titleLabel.text = @"needs to be more than one colour";
        break;

and so on…

Can I in some way define whats in a html file in tags in the code in these switches rather than having seperate html files? If so how would I do this?

Cheers,

Answer 1

Assuming your HTML contains a CSS class called myCssClass where you specify your colors, and a label:

<label id="myTextElement">A Label</label>

You can programmatically execute javascript to set a different CSS class using code like this:

UIWebView *webView; 
.
.
.
[webView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"myTextElement\").className = \"myCssClass\";"];

though honestly if you watch the WWDC 2012 videos on CoreText you might be less intimidated…
