删除数组中的元素

遍历删除,顺序删除可能删除的不彻底,有遗留.错误的删除方法:

NSMutableArray <HPLonelyShopHomepageModel *>*temp = [typeListArray mutableCopy];
    [temp enumerateObjectsUsingBlock:^(HPLonelyShopHomepageModel * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        if (!obj.userList.count) {
            [temp removeObject:obj];
        }
    }];

逆序删除即可:

NSMutableArray <HPLonelyShopHomepageModel *>*temp = [typeListArray mutableCopy];
    HPLog(@"之前:%td",temp.count);
    [temp enumerateObjectsWithOptions:NSEnumerationReverse usingBlock:^(HPLonelyShopHomepageModel * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        if (obj.userList.count == 0) {
            [temp removeObject:obj];
            HP_DEBUG_Log(@"走了删除方法");
        }
    }];
