1.创建可显示的字符集。

@property (nonatomic, copy) NSString *filter;

@property (nonatomic, strong) NSAttributedString *merchantShopNameRich;

2.获取到具体的搜索字符。

- (NSAttributedString *)merchantShopNameRich {

    

    if (!_merchantShopNameRich) {

        

        _merchantShopNameRich = [self stringColor:self.merchantShopName fontSize:15 searchText:self.filter];

    }

    

    return _merchantShopNameRich;

}

3.将确认的搜索字符与搜索结果进行匹配处理。

- (NSAttributedString *)stringColor:(NSString *)string fontSize:(NSInteger)fontSize searchText:(NSString *)fiter{

    //以不区分大小写的方式呈现文字

    UIColor * color = [UIColor colorTextAssistColor];

    NSMutableAttributedString * richStr = [[NSMutableAttributedString alloc]initWithString:string?:@""];

    NSDictionary *dic = @{NSFontAttributeName:[UIFont systemFontOfSize:fontSize],NSForegroundColorAttributeName:color};

    

    if (fiter.length <= 0) {

        return nil;

    }

    

    if ([string rangeOfString:fiter options:NSCaseInsensitiveSearch].location != NSNotFound) {

        NSRange range = [string rangeOfString:fiter options:NSCaseInsensitiveSearch];

        [richStr addAttributes:dic range:range];

    }

    

    return richStr;

}

4.在cell或控件内部对字符集进行具体的赋值。

- (void)setModel:(SearchModel *)model {

    

    _model = model;

    

    SearchCellFrame *cellFrameModel = [[SearchCellFrame alloc] initWithContent:model];

    _collectionView.frame = cellFrameModel.collecttionFrame;

    

    [_headeImage sd_setImageWithURL:[NSURL URLWithString:model.storefrontimagePath] placeholderImage:IMG(@"load_Price")];

    // 店铺详情

    _storeName.attributedText = model.merchantShopNameRich;    

    _signatureLab.text = model.signature;

    _totalLabel.text = [NSString stringWithFormat:@"已售：%ld", model.orderCountNum];

    _distanceLabel.text = model.distanceKM;

    

    if (model.isShopTime == 0) {

        _isSalesLab.hidden = NO;

    }else {

        _isSalesLab.hidden = YES;

    }

    [self.collectionView reloadData];

}

5.在控制器中，返回的结果赋值给filter字符串。

for (SearchModel * model in arrays) {

                    

                    model.filter = weakSelf.saerchName;

                    

                    for (FoodDetailModel *item in model.Commodity) {

                        

                        item.goodsFilter = weakSelf.saerchName;

                    }

                }
