How to disable text selection WKWebView programatically?

Question

Problem

You can select text in the WKWebView.

Desired Behaviour

You should not be able to select text in the webview at all.

What I've tried

1. Loading NSString * jsCallBack = @"window.getSelection().removeAllRanges();"; using evaluateJavaScript:completionHandler:
2. doing the above using "document.documentElement.style.webkitUserSelect='none'"
3. webView.configuration.selectionGranularity = nil; <-- This one doesn't make sense as selectionGranularity can only take two predefined values, but it was worth a try.
4. Tried looking for a solution inside the storyboard, couldn't find a solution that wouldn't disable user interactions.

What I can not do

Changing the HTML/CSS code is not an option at this time, if I could change it this answer would probably work.

Answer 1

Semi private gray area solution relying on private web views hierarchy and its tap gestures. As a bonus doesn't rely on private class & method symbols, but if order of tap gestures would change it would break.

@import WebKit;
@interface ViewController ()

@property(null_resettable, nonatomic,strong) WKWebView *view;
@end

@implementation ViewController

@dynamic view;

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view = [WKWebView new];

    for (UIView *view in self.view.subviews) {
        for (UIView *innerView in view.subviews) {
            if (innerView.gestureRecognizers.count > 0) {
                NSMutableArray<UIGestureRecognizer*> *gestureRecognizers = [innerView.gestureRecognizers mutableCopy];
                [gestureRecognizers removeObjectAtIndex:0];
                innerView.gestureRecognizers = [gestureRecognizers copy];
            }
        }
    }

    [self.view loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://stackoverflow.com/questions/43227437/how-to-disable-text-selection-wkwebview-programatically"]]];
}
@end

Answer 2

**// add gesture on viewDidLoad**
override func viewDidLoad() 
{
    super.viewDidLoad()
    let longPress:UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: nil, action: nil)
    longPress.minimumPressDuration = 0.3
    webView.addGestureRecognizer(longPress)
}

**//also inherit the UIGestureRecognizerDelegate**

class ViewController: UIViewController, UIGestureRecognizerDelegate {
}
