自动归档解档工具

1.首先获取一个类的所有属性

+ (NSArray *)getAllPropertyWithClass:(Class)class
{
    NSMutableArray *propertyArr = [[NSMutableArray alloc] init];
    unsigned int count;
    while (class != [NSObject class]) {
        objc_property_t *properties = class_copyPropertyList(class, &count);
        for(int i = 0; i < count; i++)
        {
            objc_property_t property = properties[i];
            NSString *propertyName = [[NSString alloc] initWithCString:property_getName(property) encoding:NSUTF8StringEncoding];
            if ([propertyName isEqualToString:@"distace"]) {
                continue;
            }
            [propertyArr addObject:propertyName];
        }
        if (properties) {
            free(properties);
        }
        //得到父类的消息
        class = class_getSuperclass(class);
    }
    return propertyArr;

}

2.用kvc对每个属性进行归档解档

- (instancetype)initWithCoder:(NSCoder *)coder

{

    self = [super init];

    if (self) {

        NSArray *properties = [GetAllPropertyTool getAllPropertyWithClass:[self class]];

        for (NSString *property in properties) {

            @try {

                [self setValue:[coder decodeObjectForKey:property] forKey:property];

            }

            @catch (NSException *exception) {

                

            }

            @finally {

                

            }

            

        }

    }

    return self;

}

 

- (void)encodeWithCoder:(NSCoder *)coder

{

    NSArray *properties = [GetAllPropertyTool getAllPropertyWithClass:[self class]];

    for (NSString *property in properties) {

        @try {

            [coder encodeObject:[self valueForKey:property] forKey:property];

        }

        @catch (NSException *exception) {

            

        }

        @finally {

            

        }

        

    }

}
