RHKeyValueStore

Key-Value storage tool,based on WCDB (WeChat DataBase).

About WCDB : Tencent/WCDB , 微信WCDB进化之路 - 开源与开始

Easy KV database, can use it instead of NSUserDefaults.

Installation

Add pod 'RHKeyValueStore' to your Podfile and run pod install.
Import <RHKeyValueStore.h>.

Usage

Already #define KeyValueStore [RHKeyValueStore store] ,
so you can use KeyValuStore to get the store instance.

• Integer

[KeyValueStore setInteger:10 forKey:@"someInteger"];
[KeyValueStore integerForKey:@"someInteger"];

• Double

[KeyValueStore setDouble:12.4 forKey:@"someDouble"];
[KeyValueStore doubleForKey:@"someDouble"];

• Bool

[KeyValueStore setBool:YES forKey:@"boolean"];
[KeyValueStore boolForKey:@"boolean"]; 

• String

[KeyValueStore setString:@"lalal" forKey:@"onestring"];
[KeyValueStore stringForKey:@"onestring"];

• Object

JSON encoding/decoding

TestObject *obj = [TestObject new];
obj.host = @"github";
obj.ipAddress = @"127.0.0.1";
obj.count = 10;
[KeyValueStore setJsonObject:[obj yy_modelToJSONObject] forKey:@"jsonModel"];
    
NSDictionary *ano = [KeyValueStore jsonObjectForKey:@"jsonModel"];
TestObject *obj2 = [TestObject yy_modelWithDictionary:ano];

Archive/Unarchive (confirm NSCoding Protocol)

[KeyValueStore setArchiveObject:obj forKey:@"archiveObj"];
TestObject *obj3 = [KeyValueStore unarchiveObjectForKey:@"archiveObj"];

• Isolation Store

Use method + (instancetype)storeWithLabel:(NSString *)label to create a new table.

Like:

NSString *userId = @"my_user_id";
RHKeyValueStore *userStore = [RHKeyValueStore storeWithLabel:userId];
[userStore setInteger:30 forKey:@"someInteger"];
    
NSLog(@"global -- %zd, user -- %zd", [KeyValueStore integerForKey:@"someInteger"], [userStore integerForKey:@"someInteger"]);

Console output global -- 10, user -- 30 .

• Other Methods

// get all keys
NSArray *keys = [KeyValueStore allKeys];
// get pair count
NSUInteger count = [KeyValueStore getKVCount];
// clear current table
[userStore clear];
