[CFArray release]: message sent to deallocated instance
- by arielcamus
Hi,
I'm using the following method in my code:
- (NSMutableArray *) newOrderedArray:(NSMutableArray *)array ByKey:(NSString *)key ascending:(BOOL)ascending {
NSSortDescriptor *idDescriptor = [[NSSortDescriptor alloc] initWithKey:key ascending:ascending];
NSArray *sortDescriptors = [NSArray arrayWithObject:idDescriptor];
NSArray *orderArray = [array sortedArrayUsingDescriptors:sortDescriptors];
[idDescriptor release];
NSMutableArray *result = [NSMutableArray arrayWithArray:orderArray];
return result;
}
Is this a well-coded convenience method? As I think, it returns an autoreleased NSMutableArray.
This method is called by another one:
- (id) otherMethod {
NSMutableArray *otherResult = [[[NSMutableArray alloc] initWithCapacity:[otherArray count]] autorelease];
// I add some stuff to otherResult and then...
NSMutableArray *result = [dbUtils newOrderedArray:otherResult ByKey:@"objectId" ascending:NO];
return result;
}
This method (otherMethod) is called in some view controller where I want to store returned array and release it when deallocating the view controller. However, when [result retain] is called in this view controller (because I need it to be available and I can't allow it to be deallocated) I receive the following error:
[CFArray release]: message sent to deallocated instance
I've tried to log [result retainCount] just before calling retain and it print "1". I don't understand why an error is thrown when calling retain.
Thank you,
A
