I am attempting to create NSAttributedString from given HTML string, with paragraph and hyperlink. Everything is fine, except styling hyperlink.
My code to style looks like:
func htmlAttributed() -> NSAttributedString? {
do {
let htmlCSSString = "<style>" +
"* {" +
"font-size: 12px !important;" +
"color: #9D9B98 !important;" +
"}" +
"p" +
"{" +
"font-size: 12px !important;" +
"color: #9D9B98 !important;" +
"font-family: Helvetica !important;" +
"}" +
"a" +
"{" +
"font-size: 12px !important;" +
"color: hotpink !important;" +
"font-family: Helvetica !important;" +
"}" +
"a:link" +
"{" +
"text-decoration: none !important;" +
"color: hotpink !important;" +
"}" +
"a:visited" +
"{" +
"text-decoration: none !important;" +
"}" +
"</style> \(self)"
guard let data = htmlCSSString.data(using: String.Encoding.utf8) else {
return nil
}
return try NSAttributedString(data: data,
options: [.documentType: NSAttributedString.DocumentType.html,
.characterEncoding: String.Encoding.utf8.rawValue],
documentAttributes: nil)
} catch {
print("error: ", error)
return nil
}
}
and it giving great result when I open it in website. But translation to NSAttributedString works only for p mark, not for hyperlink.
For testing I use this part of code
<p>This is not a link <b><a class='test' href='test' target='_blank'>This is a link</a></b></p>
On w3c playground I have:
On iPhone I've got:
If you're using a UILabel, try using UITextView instead and change link colors using linkTextAttributes. This way your links will also be tappable.
textView.linkTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.systemPink]
I tried to load a .heic image using WKWebView.loadFileURL on iOS 11.4 but got a blank page.

if fileExtension == "heic" {
guard let fileData = fileData,
let image = UIImage(data: fileData),
let jpegData = image.jpegData(compressionQuality: 1.0)
else {
return
}
let base64JPG = jpegData.base64EncodedString(options: .lineLength64Characters)
let htmlImgTag = "<img src=\"data:image/jpeg;base64, " + base64JPG + "\" alt=\"" + fileUrl.lastPathComponent + "\" />"
let imageHTML = "<!DOCTYPE html>" +

for some reason i have a dispatch_async thread, and it crashes unless i have a NSLog() method executed in front of it. the block runs a method that retrieves a username from a database.
crash:

user_web_communicator *usrWeb = [[user_web_communicator alloc]init];
NSString *author = [usrWeb getUsernameFromID:author_string];
[_author_label setText:[NSString stringWithFormat:#"Author: %#",author]];

working:
NSLog(#"Fetching author for id: %#",author_string);

can you please tell me why this could be happening? i dont want to keep the NSLog() there because it runs it several times and gets in the way when trying to read output. Thank you in advance =)
It is undefined behavior to set the text property of a label in a background thread, or any other UI changes for that matter. Since it is undefined behavior I can not explain why it works with the NSLog but you need to dispatch setting the label's text to the main thread.
