NSArray initWithObjects only initializing with some of the objects

Question

I've encountered a weird issue thats causing me quite the headache. I am initializing an NSArray object using initWithObjects. I'm passing in 7 objects but immediately afterwords, if I log the count of the array, I only have a count of 3. Has anyone else seen this? I've used this method countless times with no problem before and I can't see what I'm doing wrong. The code is below:

-(DMORecipe *) saveRecipe:(NSNumber *)recipeID recipeTitle:(NSString *)title recipeDescription:(NSString *)description pictureFile:(NSString *)picFile preparationTime:(NSString *)prepTime cookingTime:(NSString *)cookTime ovenTemperature:(NSString *)ovenTemp {
    NSArray *newRow = [[NSArray alloc] initWithObjects:recipeID,title, description, picFile, prepTime, cookTime, ovenTemp, nil];
    NSLog(@"Before update, the number of args is %i", [newRow count]);
}

Do I have a type-o somewhere that I'm missing? You can see I'm passing in 7 objects to the array initializer but the NSLog method shows [newRow count] = 3.

nhahtdh is right. Look at his post below. In the method initWithObjects, passing nil as a parameter signals that that is the last object passed in. On a side note, I would recommend using an NSURL instead of an NSString for your picFile parameter, as NSURLs are more efficient when storing path data.

If any of the object passed in is nil, the rest of the argument will be ignored.

In this case, it seems that picFile is nil.
