不确定为什么 linkTextAttributes 不适用于字体名称。但我们可以通过更新 NSAttributedString 的链接属性来实现这一点。检查下面的代码。
do {
let htmlStringCode = "For more info <a href=\"http://www.samplelink.com/subpage.php?id=8\">Click here</a>"
let string = try NSAttributedString(data: htmlStringCode.dataUsingEncoding(NSUTF8StringEncoding)!, options: [NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: NSUTF8StringEncoding], documentAttributes: nil)
let newString = NSMutableAttributedString(attributedString: string)
string.enumerateAttributesInRange(NSRange.init(location: 0, length: string.length), options: .Reverse) { (attributes : [String : AnyObject], range:NSRange, _) -> Void in
if let _ = attributes[NSLinkAttributeName] {
newString.removeAttribute(NSFontAttributeName, range: range)
newString.addAttribute(NSFontAttributeName, value: UIFont.systemFontOfSize(30), range: range)
}
}
textField.attributedText = newString
textField.linkTextAttributes = [NSForegroundColorAttributeName : UIColor.redColor(), NSUnderlineStyleAttributeName : NSUnderlineStyle.StyleNone.rawValue]
}catch {
}
这是目标C代码:
NSDictionary *options = @{NSDocumentTypeDocumentAttribute : NSHTMLTextDocumentType};
NSData *data = [html dataUsingEncoding:NSUnicodeStringEncoding allowLossyConversion:NO];
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithData:data options:options documentAttributes:nil error:nil];
NSMutableAttributedString *attributedStringWithBoldLinks = [[NSMutableAttributedString alloc] initWithAttributedString:attributedString];
[attributedString enumerateAttributesInRange:NSMakeRange(0, attributedString.string.length) options:NSAttributedStringEnumerationReverse usingBlock:^(NSDictionary<NSString *,id> * _Nonnull attrs, NSRange range, BOOL * _Nonnull stop) {
if ([attrs objectForKey:NSLinkAttributeName]) {
[attributedStringWithBoldLinks removeAttribute:NSFontAttributeName range:range];
[attributedStringWithBoldLinks addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"YourFont-Bold" size:16.0] range:range];
}
}];
self.linkTextAttributes = @{NSForegroundColorAttributeName : [UIColor redColor]};
self.attributedText = attributedStringWithBoldLinks;
