Get property name as a string


I need a way to pass a property and get the name assigned to it. Any suggestions?

@property (nonatomic, retain) MyObject *crazyObject;

NSString *str = SOME_WAY_TO_GET_PROPERTY_NAME(crazyObject);
// Above method should return @"crazyObject"

Solution

  • You can try this:

    unsigned int propertyCount = 0;
    objc_property_t * properties = class_copyPropertyList([self class], &propertyCount);
    
    NSMutableArray * propertyNames = [NSMutableArray array];
    for (unsigned int i = 0; i < propertyCount; ++i) {
      objc_property_t property = properties[i];
      const char * name = property_getName(property);
      [propertyNames addObject:[NSString stringWithUTF8String:name]];
    }
    free(properties);
    NSLog(@"Names: %@", propertyNames);
