因为sdk里面的属性类缺少以下参数，我需要使用类别，给它添加运营商信息
以下几步，就可以给它追加属性
1、添加类别 TuyaSmartDeviceModel+CarrierInfo
2、添加卡号信息

@interface TuyaSmartDeviceModel (CarrierInfo)

@property (nonatomic , copy)NSString *iccid;//卡号

@property (nonatomic , assign)NSInteger carrierType;

- (void)checkCarrierCardInfo;

@end

3、下面一步是最重要的步骤

#import "TuyaSmartDeviceModel+CarrierInfo.h"
#import <objc/runtime.h>

@implementation TuyaSmartDeviceModel (CarrierInfo)
- (void)checkCarrierCardInfo{
    if (self.iccid) {
        NSInteger supplier =  [[CachCardModelManager sharedInstance]checkSupplierType:self.iccid devid:self.devId];
        self.carrierType = supplier;
    }
    else{
        self.carrierType = 0;
    }
}
- (void)setIccid:(NSString *)iccid{
    objc_setAssociatedObject(self, @selector(iccid), iccid, OBJC_ASSOCIATION_COPY_NONATOMIC);
}
- (NSString *)iccid{
    return objc_getAssociatedObject(self, _cmd);
}
- (void)setCarrierType:(NSInteger)carrierType{
    objc_setAssociatedObject(self, @selector(carrierType), @(carrierType), OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}
- (NSInteger)carrierType{
    return [objc_getAssociatedObject(self, _cmd) integerValue];
}
@end

4、使用 ：1> import "TuyaSmartDeviceModel+CarrierInfo.h"
2> 使用它的checkCarrierCardInfo方法
