ios WKWebView 加载本地的html ,这样有的会出现图片样式不显示的情况， 解决办法 ： Added folders 选择 Create folder references ；或者将文件压缩，拖到项目中，然后解压到沙盒目录下
1 、加载本地html
不带参数
NSString * pathString = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"app/html"];
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:pathString]]];
带参数
NSString * pathString = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"app/html"];
NSString * urlString2 = [[NSString stringWithFormat:@"?sid=%@",@"cookie"]stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlString2 relativeToURL:[NSURL fileURLWithPath:pathString]]]];
2、加载沙盒
不带参数
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * path = [paths objectAtIndex:0];
path = [path stringByAppendingString:[NSString stringWithFormat:@"/app/html/index.html"]];
NSURL *url = [NSURL URLWithString:[[NSString stringWithFormat:@"file://%@",path] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]] relativeToURL:[NSURL fileURLWithPath:NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES).firstObject]];
[self.wkView loadFileURL:url allowingReadAccessToURL:[NSURL fileURLWithPath: [paths objectAtIndex:0]]];
带参数
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * path = [paths objectAtIndex:0];
path = [path stringByAppendingString:[NSString stringWithFormat:@"/app/html/index.html"]];
NSURL * url = [NSURL fileURLWithPath:path isDirectory:NO];
NSURLComponents *urlComponents = [NSURLComponents componentsWithURL:url resolvingAgainstBaseURL:NO];
[queryItemArray addObject:[NSURLQueryItem queryItemWithName:@"version" value:[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]]];
[urlComponents setQueryItems:queryItemArray];
[self.wkView loadFileURL:urlComponents.URL allowingReadAccessToURL:[NSURL fileURLWithPath: [paths objectAtIndex:0]]];
