Problem with a warning for not declared

[Ajaxx]

-(NSMutableArray *)readProperties {
	
	// For error information
	NSError *error;
	//Prepare File Manager
	NSString *filePath = [self dataFilePath];
	NSFileManager *fileMgr;
	fileMgr = [NSFileManager defaultManager];
	
	//Check from what module the call is coming from to ecide what to do
	if ([fileMgr fileExistsAtPath: filePath] == NO) {
		NSLog (@"File not found");
		//File does not exists, this is the first time the game starts
		//Set up default parameters
		NSString *fileString =@"0\n30\n30\n10\n1\n1\n1\n2\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n";
		// Write default parameters to file
		[fileString writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:&error];
		NSArray *propertiesArray = [fileString componentsSeparatedByString:@"\n"]; // each line, adjust character for line endings
		[fileString release];
	}
	else {		//File exists
		NSLog (@"File exists");
		NSString *fileString = [NSString stringWithContentsOfFile:filePath
																 encoding:NSUTF8StringEncoding
																	error:nil]; // reads file into memory as an NSString
		NSArray *propertiesArray = [fileString componentsSeparatedByString:@"\n"]; // each line, adjust character for line endings
		[fileString release];
	}
	//>>>>Warning: 'propertiesArray undeclared'	
	NSMutableArray *propArray = [NSMutableArray addObjectsFromArray:propertiesArray];	
		
	return propArray;
}

Sorry for the newbie question but could someone nice please tell me why the propertiesArray is warned as undeclared?

The two "propertiesArray" variables are declared inside a block (a compound statement surrounded by {} ), and they are not available outside of that block; each block has its own scope just like each function has its own scope. Variables declared inside a scope are not usually available outside that scope.

The fix in your case is to declare "propertiesArray" once, before the if statement. Then you can set it later.

PS - don't release fileString. You did not alloc, copy, retain, or "new" it, so you should not release it here.
