问题
I'm adding some PDF links to my UIWebView and every time one loads and I make a scroll gesture, I get this error:
objc[910]: UIPDFPageRenderOperation object 0x14acaca10 overreleased while already deallocating; break on objc_overrelease_during_dealloc_error to debug
So, is the UIPDF is being deallocated while I try to scroll?
Anyone have a hint?
回答1:
My solution was to disconnect the iPad from the Mac and run separately Xcode or Instruments. The crashes with an overrelease PDF error went away. Kinda stinks that I can't open any of the controllers/views where there is a webview with a PDF during my debugging sessions, but at least it's not crashing.
