从UIWebView更改为WKWebView

Question

I'm trying to change my UIWebView to WKWebView .

My WebPageViewController just looks this simple on Storyboards:

I'd like to implement the Reading View and back buttons and estimated progress, but I'm not sure if I'm even getting this first step right.

If the first step is right though, and I'm wanting to set up the configuration, am I adding something like this to my code?: WKWebViewConfiguration *theConfiguration = [[WKWebViewConfiguration alloc] init];

And would I need to add a @property (strong, nonatomic) WKWebViewConfiguration *configuration; to get it all working?

Here's my code changes so far if needed:

WebPageViewController.m UIWebView

@property (strong, nonatomic) IBOutlet UIWebView *webView;

-(void)viewWillAppear:(BOOL)animated {
    NSURL *url = [NSURL URLWithString:stringWeb];

    [self.webView loadRequest:[NSURLRequest requestWithURL:url]];
}

WebViewController.m WKWebView

@property (strong, nonatomic) IBOutlet WKWebView *webView;

-(void)viewWillAppear:(BOOL)animated {
NSURL *url = [NSURL URLWithString:stringWeb];

[self.webView loadRequest:[NSURLRequest requestWithURL:url]];
}

You can instantiate and set the WKWebViewConfiguration on the web view in viewDidLoad without storing it in a property.

- (void)viewDidLoad {
  [super viewDidLoad];

  WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
  // ...
  self.webView.configuration = configuration;
}
