有时候在WKWebView加载页面后会发现页面的字会很小, 这是因为原网页没有做手机屏幕尺寸的适配, 那么在后台不做调整的情况下我们移动端怎样来适配页面呢?
以下代码可以适配大小:
NSString *jScript = @"var meta = document.createElement('meta'); meta.setAttribute('name', 'viewport'); meta.setAttribute('content', 'width=device-width'); document.getElementsByTagName('head')[0].appendChild(meta);";
WKUserScript *wkUScript = [[WKUserScript alloc] initWithSource:jScript injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:YES];
WKUserContentController *wkUController = [[WKUserContentController alloc] init];
[wkUController addUserScript:wkUScript];
WKWebViewConfiguration *wkWebConfig = [[WKWebViewConfiguration alloc] init];
wkWebConfig.userContentController = wkUController;
WKWebView *webView = [[WKWebView alloc] initWithFrame:self.view.frame configuration:wkWebConfig];
[self.view addSubview:webView];
webView.navigationDelegate = self;
