First off, thank you Nick.
I corrected every location where i had made the mistake,
but i still get the runtime error, in this block of code.
-(int)addName:(NSString *)name{
ADTreeViewItem *item = [[ADTreeViewItem alloc]init];
[item setDisplayString:name];
[arrayofNames addObject:item];
return [arrayOfNames count];
}
I was thinking that the "item" variable was not in a good place,
and was released after the function ended,and that might cause
problems but then i red up on Array's and they retain objects, so
it should not matter where the object is allocated from.
[arrayofNames addObject:item];
this somehow crashes the app without an error message in the NSLog.
I think you might also be having trouble with the line
arrayOfNames = [[NSMutableArray array] init];
The way you've done it, the array won't be retained because -array is
a convenience method and will return an autoreleased object. You
could use
arrayOfNames = [[NSMutableArray array] retain];
or
arrayOfNames = [[NSMutableArray alloc] init];
instead. For the latter, you won't need a -retain message because
arrayOfNames is an instance variable in your class.
