Question

Hello I am taking records from core data entity and displaying it in tableview.
My app is crashing when I view records and coming back but, not all time.
Here is my code

//load existing lyrics

- (void)loadLyricsForSong {
    NSMutableArray *arrayOfLyrics = [[NSMutableArray alloc] initWithArray:[song.songLyrics  allObjects]];
        NSSortDescriptor *nameDescriptor  = [[NSSortDescriptor alloc]initWithKey:@"startTime" ascending:YES];//name wise sorting in asecending order

        NSArray *sortDescriptors = [[NSArray alloc]initWithObjects:nameDescriptor,nil];
        [arrayOfLyrics sortUsingDescriptors:sortDescriptors];


        [self setLyricsArray:arrayOfLyrics];//setting mutable array with places
        [nameDescriptor release];
        [sortDescriptors release]; //releasing objects
        [arrayOfLyrics release];
        [self.tableView reloadData]; 

    }

I am calling this loadLyricsForSong method on viewWillAppear. and released lyricsArray in Dealloc method..

And exceptions are

> *** -[UITouchData retain]: message sent to deallocated instance 0x5da0860
> *** -[NSConcreteNotification retain]: message sent to deallocated instance 0x5d919b0
> *** -[CFArray retain]: message sent to deallocated instance 0x5b47d30

Please help..
Thank in advance

What does your @property declaration for lyricsArray look like? If it is set to assign and not retain then this code will cause a crash. Ensure that it is set to retain.
