Question

Ok so I -roughly- want this code:

test1.m:

Foo *foo = [[Foo alloc] init];
foo.x = 1.0f;

[staticClass bar:*foo.x];

staticClass.m:

-(void)bar:(float *)argVar
{
  *argVar += 1.0f;
}

So I’m pointing the argVar to a property of the Foo class. Obivously the current code doesn’t work.

What’s the proper syntax for/way to do this?

Answer 1

I think that the proper way to do it is this:

float tmp = foo.x;
[staticClass bar:&temp];
foo.x = tmp;

and StaticClass.m should look like this:

+(void) bar:(float *) argvar // < not plus instead of minus, denotes static method
{
     *argVar = 1.0f;
}
