WKWebView加载本地HTML资源的正确姿势

1.首先将资源文件放在同一文件夹(html,css,js等)

2.将资源文件夹添加到工程目录时注意选择Create folder references(即蓝色文件夹)

相关代码：

WKWebViewConfiguration *config = [WKWebViewConfiguration new];

[config.preferences setValue:@YES forKey:@"allowFileAccessFromFileURLs"];

 self.webView = [[WKWebView alloc] initWithFrame:self.view.bounds configuration:config];

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"fileName"];

[self.webView loadFileURL:[NSURL fileURLWithPath:filePath] allowingReadAccessToURL:[NSURL fileURLWithPath:[NSBundle mainBundle].bundlePath]];
