Rendering binary ms/doc in UIWebView is blank

Question

I'm attempting to pull down a binary file (from Salesforce) and display it in a UIWebView. However, it it showing up blank. Here's the code I'm currently running:

class SRAFileViewController: UIViewController {
    var webView: UIWebView!
    var fileData: NSData!
    var fileType: String!

    convenience init(fileData: NSData!, fileType: String!, title: String!){
        self.init()
        self.fileType = fileType
        self.fileData = fileData
        self.title = title
    }

    override func viewDidLoad() {
        self.navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Done, target: self, action: "close")
        self.view.backgroundColor = UIColor.whiteColor()
        self.navigationItem.title = self.title
        webView = UIWebView(frame: self.view.frame)
        webView.delegate = self
        let tempData = NSData(bytes: fileData.bytes, length: fileData.length)
        webView.loadData(tempData, MIMEType: self.fileType, textEncodingName: "UTF-8", baseURL: NSURL(string: "http://localhost")!)
    }

    func close(){
        self.dismissViewControllerAnimated(true, completion: nil)
    }
}

However, the UIWebView comes up blank.

The value of fileData is <d0cf11e0 a1b11ae1...00000000 0000c700 00000000> and the fileType is application/msword

Does anyone have some ideas how to get this to render properly?

Answer 1

You should see at least the binary data of your file, if the webview can't properly render it.

However,

1. self.view.frame might not be properly set in viewDidLoad. Try setting the webView frame in viewWillAppear also.
2. I don't see where you added the webView to the view.
