How to do pointer work with accessor methods in Objective-C
- by Jasconius
Basic problem statement:
I have a very good reason for doing some pointer fanciness in an app where I need to pass a decimal by reference.
So I have a class which stores many a decimal, so let's say is has a property as such:
@property (nonatomic) double myDecimalValue;
I want to pass it by reference to some other class.
[someOtherObject sendMyDecimalByReference:&myDecimalValue];
But, a problem emerges! The way that actually has to be written (because it's a property) is
[someOtherObject sendMyDecimalByReference:&decimalOrigin.myDecimalValue];
This fails to compile in objective-c
I get around it by writing the following
- (double *) myDecimalValueRef;
[someOtherObject sendMyDecimalByReference:[decimalOrigin myDecimalValue]];
Except I have dozens of these decimals and I don't want to write that stupid wrapper function for every value.
Is there a shorthand way to do this in Objective-C using just the Getter functions?
Let's just assume I have a great reason for not using NSNumber.
Thanks!
