I've enabled zombie objects and after crash I see message like this:
[MPAudioDeviceController performSelector:withObject:afterDelay:inModes:] message sent to deallocated instance
This is private class. How can I fix this bug?
FWIW, I am getting essentially the same crash reports from the field with an app. I did not know what it was related to, but now I can at least explore switching to AirPlay to drive it.
Related
I am facing this error really randomly and rarely but still want to fix it. I don't know how to reproduce it as its not happening on my device but on other users devices.
The crash log does not really help me, at least I cannot figure out where the is issue is coming from and how to solve it.

It looks like its coming from firebase but ultimately it crashes on the user defaults.
Any idea or hint how to solve this is greatly appreciated.
GULUserDefaults.m line 109
this is the headline of the crash in my firebase Crashlytics
i want to debug my exception at my app,i have read
Debugging -[NSCFDictionary setObject:forKey:]: attempt to insert nil value add so on,but these methods is happen at i am running my app,so i can use add an Exception breakpoint, click the Add (+) button at the bottom of the breakpoints list and click Add Exception Breakpoint ,and use gcc command linećbut my question is if user give me a crash report,the bug not easy happen,how to solve it ,for example:
Application received signal SIGSEGV

through i know NSArray beyond bounds,but my app have many many NSArray,and they are user report,can you give me some easy methods to find the location?
From your question what I understood is you want the method which has produced the crash in your app. May be this can help you Symbolicating iPhone App Crash Reports.

And don't have idea what is causing this error, anybody with the same problem (that found the solution lol)?
Im developing my app and yesterday while I was playing with it crashed. I wasnt debugging, so I thought I'd take a look at the crash log today.
But my surprise is that I can't see anything that can give me some info, here it is:

Hope you can help me with this, thanks.
Without the app still in memory I'm not sure there's much you can do. From experience I guess you messaged an object that has been dealloc'd. (Maybe the datasource object for your MKMapView?) I'd try running your app with zombies enabled to track it down.
[recorder deleteRecording]; works well 30 times, but around 31 it crashes.

I found that this happens when deleteRecording is trying to delete a non existent file. So check if file exists before you call it:
if ([[NSFileManager defaultManager] fileExistsAtPath:self.recorder.url.path]) {
if (![self.recorder deleteRecording])
NSLog(#"Failed to delete %#", self.recorder.url);
}
It must be a bug in AVAudioRecorder.
