Displaying ppt, doc, and xls in UIWebView doesn't work but pdf does

Question

It looks like a few people on stackoverflow get this to work but their code isn\'t posted. I\'m using

[web loadData:data MIMEType:MIMEType textEncodingName         


        

Answer 1

The only way i found to read an Office object (tested with .doc or .xls) is to save the NSData object in a temp file, then read it.

-(void)openFileUsingExtension:(NSString*)extension {
    NSString *path = [NSString stringWithFormat:@"%@temp.%@",NSTemporaryDirectory(),extension];
    NSLog(@"%@",path);

    if ([objectFromNSData writeToFile:path atomically:YES]) {
        NSLog(@"written");

        NSURL *url = [NSURL fileURLWithPath:path];
        NSURLRequest *request = [NSURLRequest requestWithURL:url];
        [self.webview loadRequest:request];
        self.webview.scalesPageToFit = YES;
        self.webview.delegate = self;
        [self.view addSubview:self.webview]; 
    }
}

then you can remove the file inside the UIWebViewDelegate method:

- (void)webViewDidFinishLoad:(UIWebView *)webView{
    NSString *path = [NSString stringWithFormat:@"%@temp.%@",NSTemporaryDirectory(),extension];
    [[NSFileManager defaultManager] removeItemAtPath:path error:nil];
}
