Installation

Cocoapods

Highlighter is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'Highlighter'

Carthage

github "younatics/Highlighter"

Usage

You can search any UIView using view.highlight(text:normal:highlight:type:) It will search subviews for the provided text and highlight them using the attributes provided.

To search all supported subview use:

view.highlight(text: "Foo", normal: normalAttributes, highlight: highlightedAttributes)

or you can limit the search to a single type using:

view.highlight(text: "Foo", normal: normalAttributes, highlight: highlightedAttributes, type: UIButton.self)

Examples

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = self.ynSearchListViewDelegate?.ynSearchListView(tableView, cellForRowAt: indexPath) as? SearchViewCell else { return UITableViewCell() }
            
  if let changedText = ynSearchTextFieldText {
    cell.highlight(text: changedText, normal: nil, highlight: [NSBackgroundColorAttributeName: UIColor.yellow])
    }
  return cell
  }
}

  • Pop implementation

    Pop implementation

    As discussed in https://github.com/younatics/Highlighter/issues/2 here is the POP implementation.

    This should be a major version change since it contains breaking changes to the syntax.

    Please give it a quick test before merging.

    Hey, Interesting lib

    I had a quick play at a protocol oriented version if you are interested

    https://gist.github.com/IanKeen/537d70bf02fad763c096e6fbb5c1dc69

    The biggest pro to this approach is you are able to break out the highlightable elements and use protocol extensions to provide a default highlighting implementation.

    The boilerplate for the elements that conform to Highlightable would have been reduced greatly if UITextView didn't use IUOs for its text/attributedText properties :(

    The only API change this introduces is the removal of the HighlighterType enum. Instead you just pass in the type of the item you are targeting i.e. UIButton.self for buttons or nil for everything.

    Let me know if you'd be interested in a PR

  • Out of bounds, case crash.

    Out of bounds, case crash.

    Problem

    App crashed when the text of UILabel is come from network data parse.May be caused by string encoding. I simulated the scene with SwiftPlayground.

    let key = "ๅคฉ"
let text = String(data: "ๆ˜Žๅคฉๅผ€ๅง‹".data(using: .unicode)!, encoding: .unicode)!
let ranges = text.lowercased().ranges(of: key)
print("matchedRanges: \(ranges)")
// matchedRanges: [Range(Swift.String.Index(_rawBits: 196608)..<Swift.String.Index(_rawBits: 393216))]

print("originText.endIndex: \(text.endIndex)")
// originText.endIndex: Index(_rawBits: 262144)

print("lowercased.endIndex: \(text.lowercased().endIndex)")
// lowercased.endIndex: Index(_rawBits: 786432)

    The upperBound of matched range is greater than the originText.endIndex.

    Solution

    Remove the lowercased option before match range and use CompareOptions.caseInsensitive as the default value of ranges method.

    I am happy to submit PR if you allow it.

  • NSAttributedString extension highlight function bug.

    NSAttributedString extension highlight function bug.

    There is a bug in the highlight function. It occurs when more than one range is in the input. Line 22: highlightString.append(self.containAttribute(originText: originText, bound: ranges[i], attributes: highlightAttributes))

    It takes wrong occurrence. Next, instead of needed one. For example if originText = "String string String" and searchText = "string", then result will be (omitting attributes) "string String String". In fact you can clearly see this bug in the introduction gif (https://raw.githubusercontent.com/younatics/Highlighter/master/Images/Highlighter.gif)

swift-highlight is a pure-Swift data structure library designed for server applications that need to store a lot of styled text. The Highlight module is memory-efficient and uses slab allocations and small-string optimizations to pack large amounts of styled text into a small amount of memory, while still supporting efficient traversal through the Sequence protocol.
