NSMutableArray not responding to addObject:

[drnkHobo]

Hey guys, a mutable array in my app is not accepting objects from another class.

Basically I add a NSMutableDictionary in one view to an NSMutableDictionary assigned in my app Delegate and pass the data to another view, in which I want to populate my table view.

So the variable in my app delegate holds the dictionary selected in the first view.Ive got his verified with NSLog.

In my table view (second view) the app delegate has data.
Then my code to add dictionary from app delegate to NSMutableArray in table view and NSMutableArray = null. . . .

Can someone look at my code and point me in the right direction???

Here is where I set the Dictionary in the first view:

 NSString *publisher = [book	objectForKey:PUB_KEY];
    NSString *name = [book objectForKey: NAME_KEY];
    NSString *description =	[book objectForKey: INFO_KEY];

	//Creating a delegate so I can access the mutable dictionary data
	TESTAppDelegate *delegate = (TESTAppDelegate *)[[UIApplication sharedApplication] delegate];
	
	NSMutableDictionary *plistDict = [NSMutableDictionary dictionaryWithObjects:[NSArray arrayWithObjects: name, publisher, description, nil] forKeys:[NSArray arrayWithObjects:@"Name", @"Publisher", @"Description", nil]];
	
	//Adding plistDict to data Dictionary
        delegate.data = plistDict;
	NSLog(@"delegate.data In First View: %@",delegate.data);

So that adds the dictionary created into delegate.data---the NSMutableDictionary in app Delegate.

Now my table view:

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
	
	TESTAppDelegate *delegate = (TESTAppDelegate *)[[UIApplication sharedApplication] delegate];
			
	        [tempArray init];
		[tempArray addObject:delegate.data ];
		NSLog(@"tempARRAY in tableview: %@",tempArray);
		
			NSLog(@"delegate.data: %@",delegate.data);	

	self.myBooks = tempArray;
	
	[self.tableView reloadData];
}

So here when the view loads every time, I init a array: tempArray, and add delegate.data to it.Then "myBooks" Mutable Array = tempArray.Which I then use to fill my tableview , cell, ect with.

now the logs say that delegate.data in the tableview IS the saved dictionary assigned in first view.But tempArray = null....


Any help or push in the right direction?

You can't just init, you have to alloc first.

but ive created them in my .h file as NSMutableArray with property and @synthesize'd them in the .m


It tells me it may not respond to -alloc. . . .

And now you need to go read the properties link in my signature.

Dear lord...

Thanks brainslick.
I was just reading it nice one.

Ive hit another problem in my app and if anyone can help me it would be appreciated.In this code:

        
        NSMutableArray *tmpArray = [[NSMutableArray alloc] init];
        NSDictionary *tempDict = [[NSDictionary alloc] init];
        
        tempDict = delegate.data; //delegate.data is a dictionary
        
        [tmpArray addObject:tempDict];
       
        self.muckArray = tmpArray;
                                       
                                        NSLog(@"tmpArray  %@",tmpArray);
                                        NSLog(@"delegate.data  %@",delegate.data);    
    
    self.myBooks = self.muckArray;
        
        
    [self.tableView reloadData];

So im using myBooks to fill my table with.
Now ive gotten it to add the selected dictionary to the myBooks array and it works fine but whenever I go select another dictionary to add it replaces the whole array.
It just overwrites the first entry?
I know its the way im doing it but I just cant see where im going wrong.nor do I have the experience.

Anyone please help.

Well, walk through your code, figure out what you are doing, and how that compares with what your desired end result is.

You are leaking the first tempDict, by the way.

well, ive figured that im just making a pointer to the dictionary.
I need to save the array I create with the dictionary..

still thinking, but thanks

I just cant think of a way to get this to work.
delegate.data (dictionary) is just one object that gets replaced.
I thought that when I use addObject: it wud add and retain that data.
Then just a matter of adding other dictionaries. . . but no joy here

Anyone have any help for me?

thanks

oh, and can all this be done in a much simpler approach with SQLite? ive a stinking feeling it can
