Our app received the crash multi times due to use Pasteboard. Under this situation when I try to use system Notes paste the content, the system notes will block too. So I write a program try to read the pasteboard, but it will also crash when I use [UIPasteboard generalPasteboard].
I'm sure this seriou bug is apple's bug, all the app will crash when launch under this situation If use UIPasteboard class. When I reboot the phone, it's ok. I have report this issue to apple but no reply, very disappointed.
