DoraemonKit
for debugging purposes. My NSLOG
calls catching by DoraemonKit
. I am getting crash reports from some of my users and I couldn't figure it out.
Crash log:

16 CoreFoundation 0x000000019816d9a0 __CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER__ + 28 (CFNotificationCenter.c:706)
My Code:
- (void)handleReceivedData:(NSNotification *)notify {
NSDictionary *receivedDic = [notify userInfo];
NSLog(@"receivedDicbt: %@",receivedDic);
It is pretty basic, actually. I am catching an NSNotification
and printing to NSLOG
.
Then DoraemonKit
catches it, as you can see in the stack trace.
I've inspected the DoraemonKit
and found the Frame 6's file; it is here:
Exception Type:
Exception Type: EXC_CRASH (SIGBUS)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Exception Note: EXC_CORPSE_NOTIFY
Termination Signal: Bus error: 10
Termination Reason: Namespace SIGNAL, Code 0xa
What can cause to this problem and how to resolve it?
