Here's an example backtrace:
You may not be able to access the arguments when you have zombies enabled. Turn it off, and when the debugger breaks, po the arguments. The selector is most useful to know, but also knowing the object argument will clue to why your instance is getting the message. The backtrace seems to show that your instance is still in the responder chain, and knowing the above arguments will tell you whether its delegation or something else. > [MHControlsTabBarController performSelector:withObject:]: message sent to > deallocated instance 0x104bc33f0 > (lldb) bt > * thread #1: tid = 0x1d07, 0x00007fff8ff5f4ce CoreFoundation`___forwarding___ > + 158, stop reason = EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0) > frame #0: 0x00007fff8ff5f4ce CoreFoundation`___forwarding___ + 158 > frame #1: 0x00007fff8ff5f3b8 CoreFoundation`_CF_forwarding_prep_0 + 232 > frame #2: 0x00007fff93680ef7 AppKit`forwardMethod + 125 > frame #3: 0x00007fff93680ef7 AppKit`forwardMethod + 125 > frame #4: 0x00007fff93680ef7 AppKit`forwardMethod + 125 > frame #5: 0x00007fff93680ef7 AppKit`forwardMethod + 125 > frame #6: 0x00007fff93680ef7 AppKit`forwardMethod + 125 > frame #7: 0x00007fff93680ef7 AppKit`forwardMethod + 125 > frame #8: 0x00007fff93680ef7 AppKit`forwardMethod + 125 > frame #9: 0x00007fff93680ef7 AppKit`forwardMethod + 125 > frame #10: 0x00007fff93680ef7 AppKit`forwardMethod + 125 > frame #11: 0x00007fff93648a83 AppKit`-[NSWindow sendEvent:] + 7994 > frame #12: 0x00007fff9364442c AppKit`-[NSApplication sendEvent:] + 4969 > frame #13: 0x00007fff9355a2fa AppKit`-[NSApplication run] + 636 > frame #14: 0x00007fff934fecb6 AppKit`NSApplicationMain + 869 > frame #15: 0x0000000100001d02 TeXnicle`main + 34 at main.m:32 > frame #16: 0x0000000100001cd4 TeXnicle`start + 52 Keary Suska Esoteritech, Inc.
