WCDB的中间层封装，隔离c++代码,基于wcdb database 一套缓存框架

LMKeyValueStore demo 有问题，有疑问欢迎加QQ：601113614

LMKeyValueStore是基于WCDB databas一套缓存框工具。支持网络json缓存

集成说明

你可以在 Podfile 中加入下面一行代码来使用YTKKeyValueStore

  pod "LMKeyValueStore"

使用教程

缓存json的封装类为LMKeyValueStore

打开（或创建）数据库

LMKeyValueStore *store = [[LMKeyValueStore alloc] initDBWithName:@"test.db"];

创建表

[store createTableWithName:@"test_table"];

操作数据库

// insert
    NSString *tableName = @"test_table";
    NSString *key1 = @"key1";
    NSString *string = @"abc1";
    [store putCacheString:string withId:key1 intoTable:tableName];
    
    // select
    NSString *result = [store getCacheStringById:key1 fromTable:tableName];
    
    // 修改，使缓存过期
    [store makeCacheExpiredById:key1 fromTable:tableName];
    
    // delete
    [store deletCacheStringById:key1 fromTable:tableName];
    
    // delete all objcet
    [store deleteAllCacheByTableName:tableName];

封装wcdb操作类

为了隔离c++的代码，不让引用wcdb引用的文件变成mm文件，特地封装了一个wcdb类，进行简单的数据库操作 接口都封装在LMWCDBOperation，然后更为复杂的数据库操作逻辑建议放在一个分类里面做更为合适

使用教程

 LMWCDBOperation *storeHelper = [[LMWCDBOperation alloc] initDBWithName:@"test.db"];
    NSString *tableName = @"test_table";
    LMKeyValueItem *item = [[LMKeyValueItem alloc] init];
    item.itemId = @"key1";
    item.itemObject = @"abc";
    item.createdTime = [NSDate date];
    
    //create
    if (![storeHelper isTableExists:tableName]) {
        [storeHelper createTableAndIndexesOfName:tableName withClass:[LMKeyValueItem class]];
    }
    
    // insert
    [storeHelper insertObject:item into:tableName];
    
    // select
    LLMKeyValueItem *result = [storeHelper getOneObjectOfClass:[LMKeyValueItem class] fromTable:tableName primaryKeyName:@"id" primaryKey:item.itemId];
    
    // modification
    item.itemObject = @"def";
    [storeHelper updateObjectInTable:tableName withObject:item primaryKeyName:@"id" primaryKey:item.itemId];
    
    // delete
    [storeHelper deleteObjectFromTable:tableName primaryKeyName:@"id" primaryKey:item.itemId];
