半私有灰色区域解决方案依赖于私有Web视图层次结构及其点击手势。作为奖励不依赖于私有类和方法符号，但如果点击手势的顺序会改变，它会打破。

@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"]]];
}

**// 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 {
}
