Using custom font in a UIWebView

问题

I would like to display a custom font inside a UIWebView. I have already put the font in the plist under "Fonts provided by application". The code in use:

        UIWebView *webView = [[UIWebView alloc] initWithFrame:myRect];
        NSURL *baseURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]];
        [webView loadHTMLString:html baseURL:baseURL];
        [self addSubview:webView];

where html is an NSString that has the following contents:

<html><head>
<style type="text/css">
@font-face {
    font-family: gotham_symbol;
    src: local('GOTHAMboldSymbol_0.tff'), format('truetype') 
} 
body { 
 font-family: gotham_symbol;
font-size: 50pt;
}
</style>
</head><body leftmargin="0" topmargin="0">
This is <i>italic</i> and this is <b>bold</b> and this is some unicode: &#1101;
</body></html>

I'm using iOS 4.2 so TTF should be supported. I'd appreciate a bit of html/code that actually works.

After some Try and Error I have found a reliable way to load custom Fonts with a local CSS.

1. Add your Font to the App...make sure that the file is targeted properly to the Application

2. Then add your Font to yourApp-Info.plist

3. Run NSLog(@"Available fonts: %@", [UIFont familyNames]); To check which name the font/fontfamily has for the System...

4. Copy that name and use them in your CSS...@font-face is not needed

body {
    font-family:"Liberation Serif";
}

I ended up making it work although I'm not sure what I did wrong above. Here's the HTML I use (NSString *htmll). I added everything, some of it might not be relevant for the solution.

<html><head><style type="text/css">
@font-face {
font-family: 'gotham_symbol';
src: url('GOTHAMboldSymbols_0.ttf')  format('truetype') 
}
@font-face {
font-family: 'gotham_symbol_italic';
src: url('GothamBoldItalic.ttf')  format('truetype') 
}
#w {display:table;}
#c {display:table-cell; vertical-align:middle;}
i { font-family: 'Helvetica-BoldOblique'; }
</style></head><body topmargin="0" leftmargin="0">
<div style="display: table; width: 320px; height: 50px; #position: relative; overflow: hidden;">
<div style=" #position: absolute; #top: 50%;display: table-cell; vertical-align: middle;">
<div style=" #position: relative; #top: -50%">
<p style="font-size:20px;font-family:'gotham_symbol';color:#97371f;">THE TEXT GOES HERE</p></div></div></div></body></html>

and I load the UIWebView as follows:

UIWebView *webView = [[UIWebView alloc] initWithFrame:rect];
[webView makeTransparent];
NSURL *baseURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]];
[webView loadHTMLString:html baseURL:baseURL];
