未解决问题：

 1 - (NSMutableArray *)houseTypes {
 2     ATTypeCellViewModel *typeVM1 = [ATTypeCellViewModel new];
 3     typeVM1.type = @"整租";
 4     typeVM1.isSelected = YES;
 5     
 6     ATTypeCellViewModel *typeVM2 = [ATTypeCellViewModel new];

13     
14     ATTypeCellViewModel *typeVM4 = [ATTypeCellViewModel new];

55 问题：self.releaseVM.houseTypes  值不变？
56 不明白
