如何更改 WKWebView 或 UIWebView 默认字体

How to change WKWebView or UIWebView default font(如何更改 WKWebView 或 UIWebView 默认字体)

问题描述

UIWebView和WKWebView默认使用什么字体?我希望能够改变这一点.但我不想在 html 字符串中执行此操作，而是希望有类似的内容:

What font does UIWebView and WKWebView use by default? I would like to be able to change that. But I don't want to do it in the html string, instead I want to have something like:

// obj-c
[webView setFont:[UIFont fontWithName:@"GothamRounded-Bold" size:14]

// swift
webView.setFont(UIFont(name: "GothamRounded-Bold", size: 14))

有没有这样的属性或其他方式?

is there such property or some other way?

推荐答案

您可以使用您的 UIFont 对象(这样您可以更轻松地设置和修改它)，但将 HTML 包装在 span 代替；font 标签已被弃用 自 HTML 4.01 起.

You can use your UIFont object (so you can set it and modify more easily), but wrap the HTML in a span instead; font tags have been deprecated since HTML 4.01.

UIFont *font = [UIFont fontWithName:@"GothamRounded-Bold" size:14];

假设您已经创建了 NSString *htmlString，您可以使用字体的属性:

Assuming you already have the NSString *htmlString created, you can use the font's properties:

htmlString = [NSString stringWithFormat:@"<span style="font-family: %@; font-size: %i">%@</span>",
                                        font.fontName,
                                        (int) font.pointSize,
                                        htmlString];

或者，您可以只提供值而不是使用 UIFont 对象:

Alternatively, you could just supply the values instead of using a UIFont object:

htmlString = [NSString stringWithFormat:@"<span style="font-family: %@; font-size: %i">%@</span>",
                                        @"GothamRounded-Bold",
                                        14,
                                        htmlString];
