Question

- (void) viewWillAppear:(BOOL)animated
{

 [super viewWillAppear:animated];

    NSString *path = [[NSBundle mainBundle] pathForResource:@"About" ofType: @"pdf"];

    NSLog(@"%@", path);

    NSURL *targetURL = [NSURL fileURLWithPath:path];

    NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];

    [_webView loadRequest:request];

}

Answer 1

只需使用以下代码在 WebView 中打开 PDF

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"About" ofType:@"pdf"]; 
[self.webVctr loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:filePath]]];

然后查看 PDF 是否存在？

这个想法可能对你有帮助

快乐的编码..
