I have a setter method (setMinimumNumberOfSides) that I want to override after using synthesize. In it, I'm putting in a constraint on the instance variable to make sure the int is within certain bounds.
Later in a custom init method, I'm setting another instance variable (numberOfSides), but I need to make sure minimumNumberOfSides and maximumNumberOfSides was set properly within bounds. I tried changing the return value on the setter to a BOOL, so I could pass back a YES or NO if it succeeded/failed, but that created a conflicting method, I'm guessing because I'm using synthesize and overriding the setter.
How can I get the info out easily to check to see if the setter was called and returned successfully?
-(void)setNumberOfSides:(int)sides
{
if ((sides < maximumNumberOfSides) && (sides > minimumNumberOfSides))
{
numberOfSides = sides;
}
else
NSLog (@"Invalid number of sides: %d is outside the constraints allowed", sides);
}
-(void)setMinimumNumberOfSides:(int)minimum
{
if (minimum > 2)
minimumNumberOfSides = minimum;
}
-(void)setMaximumNumberOfSides:(int)maximum
{
if (maximum <= 12)
maximumNumberOfSides = maximum;
}
-(id)initWithNumberOfSides:(int)sides minimumNumberOfSides:(int)min maximumNumberOfSides:(int)max
{
if (self = [super init])
{
self.minimumNumberOfSides = min;
self.maximumNumberOfSides = max;
self.numberOfSides = sides;
}
return self;
}
