WKWebView 不支持scalesPageToFit屬性 解決方案
UIWebview的內存泄露問題導致我徹底的拋棄了他，該用WkWebview
通過注入js的方式，可以實現scalesPageToFit屬性效果
代碼如下:
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 *contentWebView = [[WKWebView alloc] initWithFrame:CGRectZero configuration:wkWebConfig];
