I am building an app where there are some dynamically generated buttons in table view cells. Everything is working fine on iPhone 4 & 4S. However after a few repetitions of the workflow, on clicking a button in table, the app crashes without giving any information in the debugger. This is happening consistently. Only once I got an exception with details as:
System.Exception: Failed to marshal the Objective-C object 0x19972ac0 (type: MonoTouch.UIKit.UIControlEventProxy). Could not find an existing managed instance for this object, nor was it possible to create a new managed instance (because the type 'MonoTouch.UIKit.UIControlEventProxy' does not have a constructor that takes one IntPtr argument). at MonoTouch.ObjCRuntime.Runtime.MissingCtor (IntPtr ptr, IntPtr klass, System.Type type, MissingCtorResolution resolution) [0x00046] in /Developer/MonoTouch/Source/monotouch/src/ObjCRuntime/.pp-Runtime.cs:352 at MonoTouch.ObjCRuntime.Runtime.ConstructNSObject[NSObject] (IntPtr ptr, System.Type type, MissingCtorResolution missingCtorResolution) [0x00000] in <filename unknown>:0 at MonoTouch.ObjCRuntime.Runtime.GetNSObject (IntPtr ptr, System.Type target_type, MissingCtorResolution missingCtorResolution, System.Boolean& created) [0x00073] in /Developer/MonoTouch/Source/monotouch/src/ObjCRuntime/.pp-Runtime.cs:514 at MonoTouch.ObjCRuntime.Runtime.GetNSObjectWrapped (IntPtr ptr, IntPtr type_ptr, System.Boolean& created) [0x0000c] in /Developer/MonoTouch/Source/monotouch/src/ObjCRuntime/.pp-Runtime.cs:686 at at (wrapper native-to-managed) MonoTouch.ObjCRuntime.Runtime:GetNSObjectWrapped (intptr,intptr,int&) at at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication:UIApplicationMain (int,string,intptr,intptr) at MonoTouch.UIKit.UIApplication.Main (System.String args, System.String principalClassName, System.String delegateClassName) [0x0004c] in /Developer/MonoTouch/Source/monotouch/src/UIKit/.pp-UIApplication.cs:38 at DominosOET.Application.Main (System.String args) [0x00008] in /Users/juligupta/TFS Workspace/OET/DominosOET/Main.cs:16
This is happening on a combination of iOS 7 and iPhone 5. Can anyone shed some light on what might be causing this. I am not getting any info in the debugger.
