NSArray as a static


  • Subject: NSArray as a static
  • From: Richard Good <email@hidden>

I'm just learning Objective C and need to understand how to declare and use a static NSArray.
I think I may be confusing the Java concept of static and Objective C's concept.



What I want is how to use the Java idea of a class static variable in Objective C


Here's the code I'm trying to use:

//class name is Person
static		NSMutableArray*	relationshipMatch;

-(id)init {
	[super init];
	if (relationshipMatch==nil)
		[Person initRelationshipMatch];
	return self;
}
+ (void) initRelationshipMatch	{
	relationshipMatch = [NSArray arrayWithObjects:
		@"abc",@"def",@"hig",nil] ;
}


When I try to access the array using NSString* aString = [relationshipMatch objectAtIndex:1];

I get
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '***


Any help would be appreciated.
