I got very weird issue with managedObjectContext:save. It hasn't happened at the first time I save the context, it only happens at some point of my program. Could you help me to know why it happened and where should I should find a bug in my code? Thanks.
Here is the log:

Make sure you have no warnings
Put breakpoints in your code where you think you are setting an NSString on your object
And/Or NSLog %# the class of NSString properties of your core data objects and make sure it is some variation of an NSString. (NSLog(#"%#", [obj.property class]);)
What is happening is something that you are saving has an NSNumber object in place of an NSString. Since NSNumber does not respond to UTF8String your application is crashing.

I am keep getting this error for NSFetchedResultsControllerDelegate.
not sure what to do with it, since it happen sporadically.
I do create the records synchronized, but still ..
any ideas why could this be?
- (Activity *)createActivityWithDictionary:(NSDictionary*)dict
{
#synchronized([DBController sharedManaged])
{
Activity *act = [Activity activityWithDictionary:dict inManagedObjectContext:self.managedObjectContext];
[self saveContext];
return act;
}
}

Looks like it's trying to call the delegate back and the delegate isn't implementing a method it's supposed to.
I'm thinking either controller:didChangeObject:atIndexPath:forChangeType:newIndexPath: or controllerDidChangeContent:
Did you implement those methods in your NSFetchedResultsControllerDelegate?
I know this might seem far fetched BUT I had a very similar problem and I had all those methods implemented and then I realized I had my release commented out for the fetchedREsultsController...once I put that back in no more sigbart and works like a charm.
All I'm saying is that sometimes the error isn't always the obvious.
We would need to see a bit more code to figure it out. Thanks.
I have a table view in which Iam selecting a row of the table view and then it hits the web services, retrieves data and then displayed. Now this is my error log Iam getting.

Kindly suggest me what should i do.
You're sending the message setDownloadedLogoImage: to an NSData object, which has no idea what to do with it! One of two things has happened:
1) You have not retained something. Take a look at whatever object you expect to call setDownloadedLogoImage on and find out where you create it - you should probably be retaining it there ;)
2) (less likely) Your code is just wrong! Add it to your question and we can take a look.
We have an PhoneGap application that runs perfectly okay when using the simulator but once running this in the actual iPhone connected to mac we get an exception (errors below). Note the application was working perfectly fine before upgrade to PhoneGap0.9.6/
objc[356]: Class Connection is implemented in both /System/Library/PrivateFrameworks/Message.framework/Message and /var/mobile/Applications/D1D682A1-010B-4AE9-8761-4D553FCF8089/Frank151.app/Frank151. One of the two will be used. Which one is undefined.

UPDATE: After not much luck after trying many things we decided to downgrade the application to PG 0.9.5.1 and it worked with no issues. Not sure of the cause but something to do with PhoneGap 0.9.6 upgrade.
Start by disabling any plug ins......
webView may be referring to ChildBrowser Plugin.
NSError *error;
if (managedObjectContext != nil) {
if ([managedObjectContext hasChanges] && ![managedObjectContext save:&error]) {
DLog(#"Unresolved error %#, %#", error, [error userInfo]);
abort();
}
}
while saving some items with the above code in CoreDate i get the following exception. the managedObjectContext has 50 unresolved deletes and 700 unresolved insertions. obviously its having a problem with the deletes. any ideas on how to track it down?

You are calling removeObject: on an immutable instance of NSSet. Make sure that the set you work with is an instance of NSMutableSet. It might help us if you could post the code where you actually perform the deletes.
Recently, I've been getting intermittent error reports from my app claiming "unrecognized selector" in areas that could not possibly cause them, and yet they do.

This is the OS sending a memory warning to my app, and somehow the application class has changed into a string.

The code in question is:
[textures setObject:texture forKey:filename];
textures is type NSMutableDictionary* and never gets reassigned or deallocated (naturally, since this is a cache object). This is the only place where setObject is invoked in this method, yet according to the stack trace, textures was a string.
I also get this weirdness:

This trace is from the following code in CCTextureCache:
CCTexture2DPixelFormat pixelFormat = [self getPixelFormatForIdentifier:identifier];
How CCTextureCache changed into NSConcreteNotification after having already called a number of methods on itself is baffling to say the least.
Has anyone else noticed this sort of thing? Am I somehow getting memory corruption?
Did you check some race conditions about multi-threads ? It seems like some resource freed by another thread, and current thread send a messaged to a deallocated object.

This is often caused by memory management errors. Did you try zombies?
...with zombies enabled, messages to deallocated objects will no longer behave
strangely or crash in difficult-to-understand ways, but will instead log a message
and die in a predictable and debugger-breakpointable way. This is the tool to use
when trying to track down over-releases and premature releases.
I just ran into the same problem, but it turns out I had made a stupid mistake:
I had declared a member like this in the header file:
NSMutableDictionary* myDict;
But then initialized it like this in the .m file:
myDict = [[NSDictionary alloc] init];
which is valid and all, because the NSMutableDictionary is derived from the NSDictionary class. Therefore all calls that are inherited from NSDictionary actually worked, but the calls specific to NSMutableDictionary [setObject: forKey:] failed because I tried to invoke them on the parent class.
The mistake was really dumb, but I was also thrown off by the fact that the debugger reported the type of myDict as something totally different (neither NSDictionary, nor NSMutableDictionary). I hope this helps some other tired coder :-)
