如何在iBooks或其他PDF可读应用程序中从WebView保存PDF文件？

Question

I have an Xcode (iPhone) app with a WebView. My homepage in this WebView contains a PDF file. I can open this PDF file. But I cannot save it.

In normal Safari browser there are the buttons "Open in…" and "Open in "iBooks"". But in my WebView I can just open the PDF file. I'm not able to save/open to/in iBooks or any other app. Why that? Can somebody help me please? Thanks for every answer.

You can download pdf file in form of NSData and save it in document directory.

NSURL *url = [NSURL URLWithString:@"deu-net.com/Berlin-Buch/14Buch.pdf"];
NSData *dataPdf = [NSData dataWithContentsOfURL:url];

//Get path directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

//Create PDF_Documents directory
documentsDirectory = [documentsDirectory stringByAppendingPathComponent:@"PDF_Documents"];
[[NSFileManager defaultManager] createDirectoryAtPath:documentsDirectory withIntermediateDirectories:YES attributes:nil error:nil];

NSString *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory, @"**PUT FILENAME YOU WANT**"];

[dataPdf writeToFile:filePath atomically:YES];
