iPad UIWebView PDF rendering is giving me weird visual artifacts
- by ashwhite
I am having some difficulty using a UIWebView to render PDF files on the iPad. Everything works fine in portrait mode, but turning the device to landscape produces strange visual quirkiness. Zooming in (but not out) even the slightest will correct it, but obviously that's not an ideal workaround.
The issue occurs with any PDF file (I have tried several, all stored locally in the bundle, not retrieved from the web). I also created a clone of the project for iPhone, which seems to work just fine, so the problem is iPad-specific. The problem occurs both in the simulator as well as on a physical iPad.

Code
NSString* filePath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"pdf"];
NSData* data = [NSData dataWithContentsOfFile:filePath];
[self.webView
loadData:data
MIMEType:@"application/pdf"
textEncodingName:@"UTF-8"
baseURL:nil];
Thanks so much for your time.
