Answer 1

Try this:

     [self.m_webView loadRequest:[NSMutableURLRequest requestWithURL:[NSURL fileURLWithPath:_m_filePath]cachePolicy:NSURLCacheStorageAllowedInMemoryOnly timeoutInterval:3.0]];  

You can change timeoutInterval and cachePolicy, in sometime you have to wait more time to loading.

You may want to look at the QuickLook Framework for iOS: https://developer.apple.com/library/ios/documentation/FileManagement/Conceptual/DocumentInteraction_TopicsForIOS/Articles/UsingtheQuickLookFramework.html

It supports the following formats:

• iWork documents
• Microsoft Office documents (Office ‘97 and newer)
• Rich Text Format (RTF) documents
• PDF files
• Images
• Text files whose uniform type identifier (UTI) conforms to the public.text type (see * Uniform Type Identifiers Reference)
• Comma-separated value (csv) files

More specifically you may want to look at the QLPreviewController: https://developer.apple.com/library/ios/documentation/NetworkingInternet/Reference/QLPreviewController_Class/Reference/Reference.html#//apple_ref/occ/cl/QLPreviewController

Answer 3

with swift 2.2

For showing PDF and DOC file I have use following code snip

//Document file url
var docUrl = NSURL(string: "https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwjjwPSnoKfNAhXFRo8KHf6ACGYQFggbMAA&
url=http%3A%2F%2Fwww.snee.com%2Fxml%2Fxslt%2Fsample.doc&usg=AFQjCNGG4FxPqcT8RXiIRHcLTu0yYDErdQ&sig2=ejeAlBgIZG5B6W-tS1VrQA&bvm=bv.124272578,d.c2I&cad=rja")

let req = NSURLRequest(URL: docUrl!)
webView.delegate = self
//here is the sole part
webView.scalesPageToFit = true
webView.contentMode = .ScaleAspectFit
webView.loadRequest(req)

Note: make sure on backed side (for api) we have to define content-type as document in headers.
