Question

How can I convert a variable name into a string?

Example:

From this:

NSString *someVariable
int otherVariable

I want to get a NSString with the actual name of the variable, no matter what type it is.
So, for the two variables above I would want to get their names (someVariable, otherVariable).

I managed to solve my problem with this code snippet:

Import the objc runtime
#import <objc/runtime.h>

and you can enumerate the properties with:

- (NSArray *)allProperties
{
    unsigned count;
    objc_property_t *properties = class_copyPropertyList([self class], &count);

    NSMutableArray *rv = [NSMutableArray array];

    unsigned i;
    for (i = 0; i < count; i++)
    {
        objc_property_t property = properties[i];
        NSString *name = [NSString stringWithUTF8String:property_getName(property)];
        [rv addObject:name];
    }

    free(properties);

    return rv;
}

Hope it helps someone.
