我可以在 UIWebview 中成功打开 xlsx 文件的本地副本
NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:[NSString stringWithFormat:@"/%@",[detailItem valueForKey:@"path"]]];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
[self.documentWebview loadRequest:[NSURLRequest requestWithURL:fileURL]];
但是对于某些文件,我在控制台日志中遇到异常。我不知道这些异常来自哪里以及如何捕获它
<Warning>: exception: Could not find the end of central directory record
<Warning>: EXCEPTION SFUZipEndOfCentralDirectoryError: Could not find the end of central directory record
此文件仅开始加载
-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType <br>
- (void)webViewDidStartLoad:(UIWebView *)webView
被调用且以下代表均未被调用
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
- (void)webViewDidFinishLoad:(UIWebView *)aWebView <br>
当我尝试在某些加载文件的 webview 中加载第二个文件时,我得到didFailLoadWithError为以前的 xlsx 调用,下面是控制台日志

这是由于 UIWebview 缓存吗?如何捕获 UIWebview 异常?
