Both iOS WebView types incorrectly setting 320px viewport size on iPhone 6 and 6+ (Xamarin app)
ios,uiwebview,xamarin,viewport,wkwebview
It turns out that the necessary launch images for the higher-res iPhones were present but not properly included in the iOS project, causing the app to load at the lower resolution of previous iPhones.

UIWebView is working but it doesn't show anything
ios,objective-c,iphone,uiwebview
Ok, after a few days debugging and looking at the project again, I've fixed it. And it has been entirely my fault from the start. Stupid me. :P It turns out that I've been making the layout from Compact-w Compact-h size class in the Story board. And when I looked...
QLPreviewController and UIWebView do not display filled PDFs
PDF forms may bring along appearances or may rely on the viewer to create an appearance for the value of the field. Fairly complete PDF viewers (like Adobe Reader or Foxit) can get along with both variants well. Incomplete viewers, though, like many so called previewers, require an existing appearance...
NSURL/NSURLRequest is unexpectedly nil
ios,swift,uiwebview,nsurl,nsurlrequest
The problem is that you do not know what is nil. Add more logging, like this: let url = NSURL(string: "http://www.urartuuniversity.com/content_images/pdf-sample.pdf")! let request = NSURLRequest(URL: url) println(url) println(request) println(webView) webView.loadRequest(request) In this way, by putting your app through its paces and trying to reproduce the crash, you will discover, just...

Would a file with a response header `Cache-Control:Private` be prevented from being cached in a NSURLCache?
ios,caching,uiwebview,nsurlcache
I ended up creating a method similar to the NSURLConnectionDelegate method willCacheResponse, and replacing the Cache-Control:private header. willCacheResponse method func willCacheResponse(cachedResponse: NSCachedURLResponse) -> NSCachedURLResponse? { let response = cachedResponse.response let HTTPresponse: NSHTTPURLResponse = response as NSHTTPURLResponse let headers: NSDictionary = HTTPresponse.allHeaderFields var modifiedHeaders: NSMutableDictionary = headers.mutableCopy() as NSMutableDictionary modifiedHeaders["Cache-Control"] =...
