ios - 如何在 loadRequest 时向 UIWebView 注入(inject)自定义字体？

Question

我使用 UIWebView 以这样的缅甸字体显示搜索测试

    NSString *googleText = @"မြန်မာဘာသာ";
    NSString *googleLink = [NSString stringWithFormat:@"http://www.google.com/search?hl=my&lr=lang_my&q=%@",
                            [[googleText stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] stringByReplacingOccurrencesOfString:@"+" withString:@"%2B"
                             ]
                            ];

    [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:googleLink]]];

这是结果

有什么方法可以在从服务器加载内容时将自定义字体注入(inject)到 UIWebView 中？

我没有在我的包中加载 html 文件，所以我不能在 CSS 中使用自定义字体，如 this question或 this one

求助!谢谢!

您可以引用以下工作代码。

NSString *cssString = [[[[@"body { font-family:" stringByAppendingString:centuryGothicRegular] stringByAppendingString:@"; font-size:"] stringByAppendingString:[NSString stringWithFormat:@"%ld",normalFont]] stringByAppendingString:@"}\""] ; //1

NSString *javascriptString = @"var style = document.createElement('style'); style.innerHTML = '%@'; document.head.appendChild(style)"; // 2
NSString *javascriptWithCSSString = [NSString stringWithFormat:javascriptString, cssString]; // 3
NSLog(@"javascriptWithCSSString: \n %@", javascriptWithCSSString);
NSString *loadedContent = [webView stringByEvaluatingJavaScriptFromString:javascriptWithCSSString];
NSLog(@"loaded ocntent: %@", loadedContent);

Font name and size are declare as constant you can change according to your required font
