我正在Web视图中加载一个html页面,我想应用一个本地css文件.我从服务器接收字符串中的html,css将在我的应用程序中.例如,我想显示"你好!" 红色的.
self.articleView = UIWebView(frame : CGRect(x : self.articleButton.frame.minX, y : self.articleButton.frame.maxY + 1, width : self.frame.width - 20, height: self.frame.height - self.articleButton.frame.maxY - 10));
self.articleView.backgroundColor = UIColor.clearColor();
self.addSubview(self.articleView);
self.articleView.loadHTMLString("<html><body><h1>Hello!</h1></body></html>", baseURL: nil)
你知道怎么申请css吗？我应该尝试使用WKWebView吗？
提前致谢.
添加的委托方法UIWebView是这样
func webViewDidFinishLoad(webView: UIWebView) {
if let path = Bundle.main.path(forResource: "styles", ofType: "css") {
let javaScriptStr = "var link = document.createElement('link'); link.href = '%@'; link.rel = 'stylesheet'; document.head.appendChild(link)"
let javaScripthPath = String(format: javaScriptStr, path)
self.articleView.stringByEvaluatingJavaScript(from: javaScripthPath)
}
//Second way
do {
let cssContent = try NSString(contentsOfFile: path, encoding: NSUTF8StringEncoding as NSStringEncoding);
let javaScrStr = "var style = document.createElement('style'); style.innerHTML = '%@'; document.head.appendChild(style)"
let JavaScrWithCSS = NSString(format: javaScrStr, cssContent)
self.articleView.stringByEvaluatingJavaScriptFromString(JavaScrWithCSS as String)
} catch let error as NSError {
print(error);
}
}
希望这会帮助你。
