Today i find a bug in my app relate to UIWebView, there are two case for it, the url i request is https://estore-cn.pandora.net/Bracelets-1/
When I use UIWebView to show a web page, and I exit that page, the webView's dealloc been called, but the UI thread been blocked, and several minutes later it recovers.
This is the thread stack here when I press pause program execution button in Xcode.

I use openGLES in my IOS app. The deadlock occurs in some case. The deadlocked Threads are as following. It seem The EAGLContext presentRenderbuffer cause semaphore::wait() in the sync queue 'gputools.DYSharedMemoryTransport.0x109700000.send', then the main thread reach to wait the same queue, this is deadlock. My question is how EAGLContext presentRenderbuffer cause that wait semaphore::wait()?

EAGLContext is part of OpenGL, which is deprecated. You should switch to Metal on this link: https://developer.apple.com/documentation/coreimage/cicontext/1437609-init

What does it mean?
This is your problem:
Foundation`-[NSObject(NSKeyValueCoding) setValue:forKey:]
because after this, is raised an Exception:
CoreFoundation`-[NSException raise] + 12
You are trying to set a value for a key in your object that could not exists or has some other problem.
P.S.: Update your answer with some relevant code so I can update my answer with more explanations.
I did not have this issue before. Every thing was working fine, but recently the UITextField in my every view controller crashes when I touch at it. It throws some exception like -[UITextField window]: message sent to deallocated instance 0x11843f80. I have properly set up the IBOutlet and actions, delegate for the UITextField. Until recently I did not have this problem but with addition of new view controller this problem has come across all the view controller that I am using. When I run lldb command to trace the application, the trace log shows something like this,

What might me the issue here. Please if anyone could help me, I would really be glad.
Use Instruments for zombie. This will tell you what is really happening there.
I had this crash occurs while testing the map using Xcode 4.3.2; targeting iOS 5.1, below is the backtrace :
