Remove underline on UITextView link

Question

I'm trying the following to format links on UITextView:

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

The issue is that, the link color was changed to white, but it's still underlined.

How can I solve it?

This is my 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;
}
{
    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";
}

Answer 1

对于 Swift，它很简单：

textView.linkTextAttributes = [.underlineStyle: 0]

Answer 2

Somehow ".underlineStyle: 0" didn't work for me. so i had to clear the Underline Color and it worked for me.

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

Answer 3

It seems that the NSUnderlineStyle in your UITextView's linkTextAttributes gets overridden by CSS's link style. If you do not define a text-decoration style for your HTML the UITextView sets the underline style to styleSingle because that is the default HTML style for a link.

To remove the underline you have to add a underline style for your HTML links. You could do that by adding the following CSS to the head of the HTML:

<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

For an unknow reason, if I add the NSUnderlineStyleAttributeName in linkTextAttributes didn't work. It supposed to add NSUnderline = 0 to link, instead it add NSUnderline = 1 . So, the only solution I found is to locate that attribute and replace it when found.

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];

Here is my code. I tried this & It's work for me. Please review them. May be it's helpful for you.

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];
