删除 UITextView 上的下划线 link

Question

我正在尝试使用以下方法在 UITextView 上格式化 links：

self.textView.linkTextAttributes = @{NSForegroundColorAttributeName:[UIColor whiteColor], NSUnderlineStyleAttributeName:[NSNumber numberWithInteger:NSUnderlineStyleNone]};

问题是，link 颜色已更改为白色，但仍带有下划线。

我该如何解决？

这是我的 attributedString:

{
    NSColor = "UIDeviceRGBColorSpace 0.294118 0.254902 0.211765 1";
    NSFont = "<UICTFont: 0x7fd75a196010> font-family: \"Helvetica\"; font-weight: normal; font-style: normal; font-size: 24.00pt";
    NSParagraphStyle = "Alignment 4, LineSpacing 0, ParagraphSpacing 24, ParagraphSpacingBefore 0, HeadIndent 0, TailIndent 0, FirstLineHeadIndent 0, LineHeight 0/0, LineHeightMultiple 0, LineBreakMode 0, Tabs (\n    28L,\n    56L,\n    84L,\n    112L,\n    140L,\n    168L,\n    196L,\n    224L,\n    252L,\n    280L,\n    308L,\n    336L\n), DefaultTabInterval 36, Blocks (null), Lists (null), BaseWritingDirection -1, HyphenationFactor 0, TighteningFactor 0, HeaderLevel 0";

    CTForegroundColorFromContext = 1;
    DTGUID = "44B87A68-642A-41AA-8CBA-48531DB58C57";
    DTLinkHighlightColor = "UIDeviceRGBColorSpace 1 0 0 1";
    NSColor = "UIDeviceRGBColorSpace 0 0 0.933333 1";
    NSFont = "<UICTFont: 0x7fd75a196010> font-family: \"Helvetica\"; font-weight: normal; font-style: normal; font-size: 24.00pt";
    NSLink = "http://www.url.com";
    NSParagraphStyle = "Alignment 4, LineSpacing 0, ParagraphSpacing 24, ParagraphSpacingBefore 0, HeadIndent 0, TailIndent 0, FirstLineHeadIndent 0, LineHeight 0/0, LineHeightMultiple 0, LineBreakMode 0, Tabs (\n    28L,\n    56L,\n    84L,\n    112L,\n    140L,\n    168L,\n    196L,\n    224L,\n    252L,\n    280L,\n    308L,\n    336L\n), DefaultTabInterval 36, Blocks (null), Lists (null), BaseWritingDirection -1, HyphenationFactor 0, TighteningFactor 0, HeaderLevel 0";
    NSUnderline = 1;
}
{

Answer 1

这是我的代码。我试过了 & 它对我有用。请检查它们。可能对你有帮助。

emailTV = [[UITextView alloc] initWithFrame:yourFrame];
emailTV.text = @"https://www.google.co.in/?gfe_rd=cr&ei=eUMJVZrQIsTV8gflkoHwAQ&gws_rd=ssl";
emailTV.textAlignment = NSTextAlignmentLeft;
emailTV.font = [UIFont fontWithName:@"HelveticaNeue-Medium"size:14.0+fontSizeDiff];
emailTV.selectable = NO;
emailTV.scrollEnabled = NO;
emailTV.editable = NO;
emailTV.backgroundColor = [UIColor clearColor];
emailTV.dataDetectorTypes = UIDataDetectorTypeNone;
emailTV.textColor = [UIColor blueColor];
[cellVI addSubview: emailTV];

Answer 2

出于未知原因，如果我在 linkTextAttributes 中添加 NSUnderlineStyleAttributeName 无效。它应该将 NSUnderline = 0 添加到 link，而不是添加 NSUnderline = 1。因此，我找到的唯一解决方案是找到该属性并在找到时替换它。

self.textView.linkTextAttributes = @{NSForegroundColorAttributeName:[UIColor whiteColor]};

NSMutableAttributedString *res = [self.textView.attributedText mutableCopy];
[res beginEditing];
[res enumerateAttribute:NSUnderlineStyleAttributeName
                inRange:NSMakeRange(0, res.length)
                options:0
             usingBlock:^(id value, NSRange range, BOOL *stop) {
                 if (value) {
                     [res addAttribute:NSUnderlineStyleAttributeName value:@(NSUnderlineStyleNone) range:range];
                 }
             }];
[res endEditing];

[self.textView setAttributedText:res];

Answer 3

您的 UITextView linkTextAttributes 中的 NSUnderlineStyle 似乎被 CSS 的 link 样式覆盖。如果您没有为 HTML 定义 text-decoration 样式，则 UITextView 会将下划线样式设置为 styleSingle，因为这是 [=] 的默认 HTML 样式27=].

要删除下划线，您必须为 HTML link 添加下划线样式。您可以通过将以下 CSS 添加到 HTML 的 head 来实现：

<style type='text/css'>
   a { text-decoration: none }
</style>

Answer 4

只需将下划线颜色设置为清晰颜色即可。

yourTextView.linkTextAttributes = @{NSUnderlineColorAttributeName: [UIColor clearColor]};

Answer 5

对于Swift，它只是：

textView.linkTextAttributes = [.underlineStyle: 0]

Answer 6

不知为何“.underlineStyle: 0”对我不起作用。所以我必须清除下划线颜色，它对我有用。

textView.linkTextAttributes = [.underlineStyle: 0, .underlineColor: UIColor.clear,]
