从带有属性的NSObject转换为NSDictionary的Obj-C简单方法？

- (NSDictionary *)dictionaryWithObject:(NSObject *)object {
    unsigned int outCount, i;
    objc_property_t *properties = class_copyPropertyList([object class], &outCount);
    NSMutableDictionary *result = [NSMutableDictionary dictionaryWithCapacity:outCount];
    
    for (i = 0; i < outCount; i++) {
        objc_property_t property = properties[i];
        NSString *propertyName = [NSString stringWithUTF8String:property_getName(property)];
        id propertyValue = [object valueForKey:propertyName];
        if (propertyValue) {
            [result setObject:propertyValue forKey:propertyName];
        }
    }
    
    free(properties);
    return result;
}

// 假设有一个名为MyObject的NSObject子类，带有属性name和age
MyObject *myObject = [[MyObject alloc] init];
myObject.name = @"John";
myObject.age = 30;

NSDictionary *dictionary = [self dictionaryWithObject:myObject];
NSLog(@"%@", dictionary);

{
    age = 30;
    name = John;
}
