Question

我想下载PDF文件，然后在webView中打开它。我搜索了那个，然后我找到了这个issu。接受的答案描述了如何下载和显示文件。当我测试它时，我在文档中找不到该文件，因为它存储在我的应用程序中。此外，我不认为该文件已保存，因为即使我传递要加载的filePath，pdf也从未在webView中显示。这是答案的代码：

// Get the PDF Data from the url in a NSData Object
NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[
    NSURL URLWithString:@"http://www.example.com/info.pdf"]];

// Store the Data locally as PDF File
NSString *resourceDocPath = [[NSString alloc] initWithString:[
    [[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent]
        stringByAppendingPathComponent:@"Documents"
]];

NSString *filePath = [resourceDocPath 
    stringByAppendingPathComponent:@"myPDF.pdf"];
[pdfData writeToFile:filePath atomically:YES];


// Now create Request for the file that was saved in your documents folder
NSURL *url = [NSURL fileURLWithPath:filePath];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

[webView setUserInteractionEnabled:YES];
[webView setDelegate:self];
[webView loadRequest:requestObj];

这就是我在日志中看到的内容：

libMobileGestalt MobileGestaltSupport.m:153: pid 2828 (my_app) does not have sandbox access for frZQaeyWLUvLjeuEK43hmg and IS NOT appropriately entitled
2017-08-01 10:29:06.882562+0100 my_app[2828:1334057] libMobileGestalt MobileGestalt.c:550: no access to InverseDeviceID (see <rdar://problem/11744455>)

我做了什么问题？如何将下载的文件放在我Documents的{{1}}应用中，以便在用户想要任何其他PDF时进行检查？

沙箱路径错误

NSString *resourceDocPath = [[NSString alloc] initWithString:[
    [[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent]
        stringByAppendingPathComponent:@"Documents"
]];

请使用您的沙箱路径而不是捆绑路径。

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
