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];
