Re: NSFileManager - Incompatible persistent store
Hey Sean, Thank you! Though this didn't quite work. I'm getting an error response in the code telling me No visible @interface for 'NSFileManger' declares the selector 'createDirectoryAtURL:attributes'.

Tom, Most path-based and non-NSError-returning file APIs are deprecated, and you should use URL+NSError methods instead: createDirectoryAtURL:withIntermediateDirectories:attributes:error: Also, using fileExistsAtPath: is rarely the right thing due to race conditions: it's possible the file didn't exist when you checked, then gets created by a different process before you get to create it. Instead, just try to create it, and be ready for a returned error like 'already exists'.

NSFileManager - Incompatible persistent store
I'm working with some code that accesses a data model in Xcode. String data
is written to an xml file in the app (Mac) and displayed in a list.
The inputted text is saved as body text and title. The app compiles but I
receive a warning upon launch,
*The managed object model version used to open the persistent store is
incompatible with the one that is used to create the persistent store.*
The app launches and I'm able to save (kinda) the inputted text, add title,
and view from a list of created titles/body text. The only problem is
the inputted text is not saved and reopened once the app launches again.
I'm assuming this has to be because of the persistent store.
I receive a warning in Xcode about this line of code dealing with the file
manager,
fileManager = [NSFileManager defaultManager];
applicationSupportFolder = [self applicationSupportFolder];
if ( ![fileManager fileExistsAtPath:applicationSupportFolder
isDirectory:NULL] ) {
[fileManager createDirectoryAtPath:applicationSupportFolder
attributes:nil];
}

Care to tell us what the warning actually is?

Issues where code produced in Snow Leopard won't work in Lion, but will compile in Xcode 4.1
Hey everyone, I'm having a strange issue with some code I produced in Snow Leopard on Xcode 4.0 The code successfully compiled on 4.0. Once I upgraded to Lion and Xcode 4.1 I had an issue where the code would compile and build the app without any errors but wouldn't work in either debug mode of release mode with it properly pointing to the correct object in IB. - Tom Miller Pixelogic Software t...@pxlc.me ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
