设置WKWebViewConfiguration
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 *config = [[WKWebViewConfiguration alloc] init];
config.userContentController = wkUController;
在WKWebView加载完成的方法中调用
- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation{
MJWeakSelf
[webView evaluateJavaScript:@"document.body.scrollHeight"completionHandler:^(id _Nullable result,NSError * _Nullable error){
int height = [result floatValue];
NSLog(@"scrollHeight高度：%.2f",[result floatValue]);
}];
}
