Default NSMutableArray with UIImageViews

I just have a simple question: how do i collect nontypical objects like UIImageViews in an Array?

I tried:
MSMutableArray *mArray;
[mArray addObject:theImageView];

but after this the count of the array is still 0.

The object isn't allocated. Objects need to be allocated before they can be used.

Code:
NSMutableArray *mArray = [[NSMutableArray alloc] init];
Now, since you called alloc, you own the object and you are responsible for releasing it.

Thank you
it was really just that simple mistake

another question:
I know that it is not possible to add the same object twice, but how do i define a new name for the second object to add it?

I try to add the same object every touch event.

Code:
-(void)touchesBegan:(NSSet *) touches withEvent:(UIEvent *)event {
     	CGRect 	points = CGRectMake(start.x, start.y, 50.0f, 50.0f);
	theImageView = [[UIImageView alloc] initWithFrame:points];
}
-(void)touchesEnded:(NSSet *) touches withEvent:(UIEvent *)event {
	[theArray addObject:theImageView];
}
The array count is not getting higher than 1.

I solved the problem:
the array overwrites itself by allocating it every touchesBegan
