I've come across a weird problem with UIWebView on an iOS 6 iPhone project. I
load a web page which is long enough so that I need to scroll vertically to see
all content. For strange reasons though UIWebView sometimes wont let me scroll
vertically. I've tracked to problem down so far that I think it has to do with
the contentSize of the embedded scrollview of UIWebView. Sometimes the
contentSize becomes {0, 0}. This happens rather reproducible after dismissing a
modal view controller presented above the view controller containing the web
view.
So far I found no other work around to alleviate the problem than KVO'ing the
contentSize property of the aforementioned scrollview and triggering a reload
of the web view content once I've detected it became {0,0}. Needless to say
that I'm not happy with this kind of hack.
BTW: I'm using a storyboard and autolayout in case this is important in any
sense.
Has anybody any idea? I would appreciate it so much!
Thanks
Tino
