Using custom font in a UIWebView

votes

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.

GOTHAMboldSymbol_0.tff - extension should be ttf (unless the font really has a tff extension on disk). – Evan Mulawski
I'm trying to find a solution to this too, but: I think you want to pass 'nil' for baseURL. – MusiGenesis
@Joris I struggle with the same problem at the moment and it would be interesting to hear if you have found a solution. – Lindemann
i posted my html below... let me know if it works for you – Joris Weimar

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

enter image description hereenter image description here

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

enter image description here

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

enter image description here

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];

For Swift and WKWebView, this worked for me:

@IBOutlet weak var webView: WKWebView!


let html = """
<!DOCTYPE html>
<head>
    <style>
        @font-face {
            font-family: 'Raleway-Regular';
            src: url('Raleway-Regular.ttf')  format('truetype')
        }
        img {
            width: 100%;
        }
        body {
            font-family: 'Raleway-Regular';
            font-size: 30px;
        }
    </style>
</head>
<body>
    My HTML Content
</body>
</html>
"""


let baseURL = URL(fileURLWithPath: Bundle.main.bundlePath)
webView.loadHTMLString(html, baseURL: baseURL)

The fonts have to be added to the XCode project as you would normally do, and Copy bundle resources

<key>UIAppFonts</key>
<array>
    <string>Raleway-Bold.ttf</string>
    <string>Raleway-Regular.ttf</string>
</array>
