1：iOS10以下版本，wkwebview不允许在沙盒里访问html里的css，js等外部资源文件，需要转移到tmp文件夹下访问；
复制到tmp文件夹下，然后从tmp文件夹下访问即可
-(NSString )spineFileMoveToTemp:(NSString )path{
if !𝑝𝑎𝑡ℎ!path {
return nil;
}
// Files in “/temp/www” load flawlesly :)
NSString *temDirPath =[NSString stringWithFormat:@”%@”, [NSString stringWithFormat:@”%@”, NSTemporaryDirectory]];
path = [path stringByReplacingOccurrencesOfString:@”/index.html” withString:@””];
[self copyFlolderFrom:path to:temDirPath];
return temDirPath;
}
2：iOS10 上下版本的跨域问题： Cross origin requests are only supported for HTTP.
解决方案：
WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
configuration.preferences.javaScriptEnabled = YES;
configuration.preferences.javaScriptCanOpenWindowsAutomatically = YES;
configuration.suppressesIncrementalRendering = YES; // 是否支持记忆读取
[configuration.preferences setValue:@YES forKey:@”allowFileAccessFromFileURLs”];
if (@available𝑖𝑂𝑆10.0,∗iOS10.0,∗) {
[configuration setValue:@YES forKey:@”allowUniversalAccessFromFileURLs”];
}
_webView = [[WKWebView alloc] initWithFrame:self.view.frame configuration:configuration];
