用过滤器更改UITextView链接的颜色？ [英] Change color of UITextView links with a filter?

问题描述

在UITextView上检测到的链接总是蓝色的。没有办法直接改变这一点。但是，我可以覆盖某种过滤器，例如，蓝色变为红色吗？

解决方案

实际上有一种方法可以做到这一点使用私有API 。
$ b $ UITextView 有一个类（code> UIWebDocumentView setUserStyleSheet：。

以下代码应该将链接的颜色更改为绿色。至少，它为我工作！ ：）
$ b $ pre $ for（UIView * subview in textView.subviews）{
[subview setUserStyleSheet：@a {color ：＃00FF00;}];
}


我知道这真的很晚，但是几个小时的Google让我没有在哪里，所以我想我会分享这个。

The detected links on a UITextView are always blue. There's no way to directly change this. But can I overlay some sort of filter which changes blue to, for instance, red?

解决方案

There's actually a way to do this with private API.

A UITextView has a (single) subview of class UIWebDocumentView, with the selector setUserStyleSheet:.

The following code should change the color of the links to green. At least, it worked for me! :)

for (UIView *subview in textView.subviews) {
    [subview setUserStyleSheet:@"a { color: #00FF00; }"];
}

I know this is really late, but hours of Googling got me no where, so I thought I'd share this.
