[ios] UIWebView의 scalesPageToFit에 해당하는 WKWebView

Program / 글쓴이

나는 대체 할 내 iOS 앱 업데이트하고 UIWebView과를 WKWebView. 그러나 나는 WKWebView. 으로 UIWebView내가 사용하는 scalesPageToFit웹 PAG는 화면 크기와 같은 크기로 표시했다 확인하기 위해 (때문에 같은 스크롤없이 전체 화면을 표시합니다).

웹에서 그 솔루션을 찾았지만 작동하지 않습니다.

- (void)webView:(WKWebView *)webView didCommitNavigation:(WKNavigation *)navigation {
    NSString *javascript = @"var meta = document.createElement('meta');meta.setAttribute('name', 'viewport');meta.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no');document.getElementsByTagName('head')[0].appendChild(meta);";
    [webView evaluateJavaScript:javascript completionHandler:nil];
}

답변

WKUserScript를 사용해 볼 수도 있습니다.

내 작업 구성은 다음과 같습니다.

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;

wkWebV = [[WKWebView alloc] initWithFrame:self.view.frame configuration:wkWebConfig];

WKWebViewConfiguration에 추가 구성을 추가 할 수 있습니다.

신속한 코드에서 nferocious76의 대답의 에코 : Swift2.x 버전

let jscript = "var meta = document.createElement('meta'); meta.setAttribute('name', 'viewport'); meta.setAttribute('content', 'width=device-width'); document.getElementsByTagName('head')[0].appendChild(meta);"
let userScript = WKUserScript(source: jscript, injectionTime: WKUserScriptInjectionTime.AtDocumentEnd, forMainFrameOnly: true)
let wkUController = WKUserContentController()
wkUController.addUserScript(userScript)
let wkWebConfig = WKWebViewConfiguration()
wkWebConfig.userContentController = wkUController
let youWebView = WKWebView(frame: CGRectZero, configuration: wkWebConfig)

swift3 버전

let jscript = "var meta = document.createElement('meta'); meta.setAttribute('name', 'viewport'); meta.setAttribute('content', 'width=device-width'); document.getElementsByTagName('head')[0].appendChild(meta);"
let userScript = WKUserScript(source: jscript, injectionTime: .atDocumentEnd, forMainFrameOnly: true)
let wkUController = WKUserContentController()
wkUController.addUserScript(userScript)
let wkWebConfig = WKWebViewConfiguration()
wkWebConfig.userContentController = wkUController
let yourWebView = WKWebView(frame: self.view.bounds, configuration: wkWebConfig)

답변

@ nferocious76과 비슷하지만 Swift 언어

var scriptContent = "var meta = document.createElement('meta');"
scriptContent += "meta.name='viewport';"
scriptContent += "meta.content='width=device-width';"
scriptContent += "document.getElementsByTagName('head')[0].appendChild(meta);"

webView.evaluateJavaScript(scriptContent, completionHandler: nil)

Xamarin Custom Renderer에서 사용하기위한 C # 버전 :

string jScript = @"var meta = document.createElement('meta'); meta.setAttribute('name', 'viewport'); meta.setAttribute('content', 'width=device-width'); document.getElementsByTagName('head')[0].appendChild(meta);";

WKUserScript wkUScript = new WKUserScript((NSString)jScript, WKUserScriptInjectionTime.AtDocumentEnd, true);
WKUserContentController wkUController = new WKUserContentController();
wkUController.AddUserScript(wkUScript);

WKWebViewConfiguration wkWebConfig = new WKWebViewConfiguration();
wkWebConfig.UserContentController = wkUController;
WKWebView webView=new WKWebView(Frame, wkWebConfig);

답변

나는 영혼 아래에서 알아 냈습니다. 콘텐츠를 장치 크기에 맞게 만듭니다.

func webView(_ webView: WKWebView, didCommit navigation: WKNavigation!) {     for making the content to fit with the device size
    let jscript = "var meta = document.createElement('meta'); meta.setAttribute('name', 'viewport'); meta.setAttribute('content', 'width=device-width'); document.getElementsByTagName('head')[0].appendChild(meta);"
    webView.evaluateJavaScript(jscript)
}

답변

내 HTML 스크립트에 아래를 추가하면 도움이되었습니다.

<meta name="viewport" content="width=device-width, shrink-to-fit=YES">

UIWebView의 scalePageToFit와 동일합니다.

Swift 5 솔루션 :

let javaScript = """
    var meta = document.createElement('meta');
                meta.setAttribute('name', 'viewport');
                meta.setAttribute('content', 'width=device-width');
                document.getElementsByTagName('head')[0].appendChild(meta);
    """

webView.evaluateJavaScript(javaScript)
