在UIWebView上打开本地pdf文件时导致应用程序崩溃

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

只需在Web视图中使用以下代码即可打开PDF

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

并查看PDF是否存在？

这个想法可能会对你有所帮助

快乐编码..

Answer 2

尝试这个：

在里面

UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)];

NSString *path = [[NSBundle mainBundle] pathForResource:@"About" ofType:@"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];

[self.view addSubview:webView];
[webView release];

这是与Web视图上的pdf加载无关的其他一些问题。 我交叉检查并找到了崩溃的实际原因。 无论如何，谢谢你的帮助
