Question

我有表视图包含文件列表，它在单击单击时推送到Web视图，正确的文件路径从表视图传递到Web视图，但Web视图加载空白页。这是我使用的代码

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"ShowPDF"]) {
    NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
    PDFViewController *destViewController = segue.destinationViewController;
NSFileManager *filemgr = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString* inboxPath = [documentsDirectory stringByAppendingPathComponent:@"Inbox"];
dirFiles = [filemgr contentsOfDirectoryAtPath:inboxPath error:nil];
destViewController.path = [documentsDirectory stringByAppendingPathComponent:[dirFiles  objectAtIndex:indexPath.row]];
}
}

要加载webview，请使用以下代码

- (void)viewDidLoad
{
    [super viewDidLoad];

   NSString *filePath =path;
   NSURL *url = [NSURL fileURLWithPath:filePath];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[pdfView loadRequest:request];
[pdfView setScalesPageToFit:YES];
   NSLog(@"%@", self.pdfView);

}

需要帮助来解决此问题。

我解决了这个问题，在下面的行

中出错

destViewController.path = [documentsDirectory stringByAppendingPathComponent:[dirFiles  objectAtIndex:indexPath.row]];

用下面的行替换

destViewController.path = [inboxPath stringByAppendingPathComponent:[dirFiles  objectAtIndex:indexPath.row]];

UIWebview加载空白页面
