I need a class, in which an instance of the class, can access all
other instances of the class.
In the following code, instances of the class are stored in a static
mutable array. To make the code work, the instance must released after
adding it to the array and retained before removing it from the array.
Otherwise dealloc will never be called, and instances will never be
removed from the array.
// MyClass.m
static NSMutableArray *_array;
@implementation MyClass
+ (void)initialize
{
_array = [[NSMutableArray array] retain]; // Is retain correct
here?
}
- (id)init
{
self = [super init];
if (self) {
[_array addObject:self];
[self release]; // ???
}
return self;
}
- (void)dealloc
{
[self retain]; // ???
[_array removeObject:self];
[super dealloc];
}
@end
This code seems to work fine. Is there a better way to do this?
