Objective- C - Looping through all properties in a class?

Question

Is there a way to loop through all properties in an object and get their \"name\" and \"value\".

I am trying to write a category to serialize objects to a string, ba

Answer 1

I don't have comment privileges yet, but to add to @Costique's answer, there is an additional attribute Type value "V" which is the name of the IVar to which a property may be bound (via synthesize). This can be readily discovered with this

@interface Redacted : NSObject

@property (atomic, readonly) int foo;

@end

---

@implementation Redacted

@synthesize foo = fooBar;

@end

// for all properties
unsigned propertyCount = 0;
objc_property_t *properties = class_copyPropertyList([object class], &propertyCount);
for (int prop = 0; prop < propertyCount; prop++)
{
    // for all property attributes
    unsigned int attributeCount = 0;
    objc_property_attribute_t* attributes = property_copyAttributeList(property, &attributeCount);
    for (unsigned int  attr = 0; attr < attributeCount; attr++)
    {
        NSLog(@"Attribute %d: name: %s, value: %s", attr, attributes[attr].name, attributes[attr].value);
    }
}
