是否可以将哈希标记发送到UIWebView中的文件URL？ [英] Is it possible to send a hash tag to a file url in UIWebView?

问题描述

我想从文件加载一个html页面，并为其添加一个哈希标记。这可能吗？

I want to load a html page from a file, and append a hash tag to it. Is this possible?

我试过了

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"someFile" ofType:@"html"];  
NSURL *fileUrl = [NSURL fileURLWithPath:[filePath stringByAppendingFormat:@"#hashtag"]];
[self.webView loadRequest:[NSURLRequest requestWithURL:fileUrl]];    
NSLog(@"fileUrl = %@, reachable? %d", fileUrl, [fileUrl checkResourceIsReachableAndReturnError:nil]);

但这会尝试查找文件 someFile.html％23hashtag ，找不到。有没有办法在创建 NSURL 对象后添加哈希？

but this tries to look for the file someFile.html%23hashtag, which can't be found. Is there a way to add the hash after the NSURL object is created?

我也试过加载将文件转换为字符串并使用 loadHTMLString ：

I've also tried loading the file into a string and using loadHTMLString:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"someFile" ofType:@"html"];
NSString *fileContents = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
[self.webView loadHTMLString:fileContents baseURL:[NSURL URLWithString:@"http://someFile.html#hashtag"]];

这里的哈希标签确实有效，但我在html中的javascript引用不起作用。这个方法的后续问题是，如何从UIWebView中作为字符串加载的html引用javascript文件，即什么是基本URL？

Here the hash tag does work, but my javascript references inside the html don't work. A follow on question from this approach would be, how do I reference javascript files from html loaded in as a string in a UIWebView, ie, what is the base url?

我能想到的一个黑客就是将我的所有javascript文件内联到html中并将其加载为字符串，但我认为必须有更好的方法！

A hack I can think of is to just put all my javascript files inline in the html and load it as a string, but I'm thinking there must be a better way!

推荐答案

我没试过这个但是如何在没有hashtag的情况下正常加载文件并用这样的东西实现UIWebViewDelegate？

I've not tried this but how about loading the file normally without the hashtag and implementing the UIWebViewDelegate with something like this?

- (void)webViewDidFinishLoad:(UIWebView *)webView {
   [webView stringByEvaluatingJavaScriptFromString:@"window.location.href = '#hashtag';"];
}
