Question

I want a property that will only accept float values between 0 and 1. I could do that in a standard way by defining float_t or double_t type for the property, but doubting, are there more elegant ways for that?

Answer 1

Do it the standard way – define a double/float property and check for validity in the setter – example:

@property (nonatomic, assign, readwrite) float property;

@synthesize property = _property;

- (void)setProperty:(float)property {
   NSAssert(property >= 0.0f && property <= 1.0f, @"Invalid value passed to property setter.").   

   _property = property;
}
