1、集成和导入可以查看此处：https://github.com/yuantiku/YTKKeyValueStore
2、数据存储
YTKKeyValueStore *store = [[YTKKeyValueStore alloc] initDBWithName:@"flynn.db"];
NSString *tableName = @"user_table";
[store createTableWithName:tableName];
// 保存
NSString *key = @"1";
NSDictionary *user = @{@"id": @1, @"name": @"flynn", @"age": @30};
[store putObject:user withId:key intoTable:tableName];
// 查询
NSDictionary *queryUser = [store getObjectById:key fromTable:tableName];
NSLog(@"query data result: %@", queryUser);
3、在不同控制器查看存储的数据（可以在任意界面，此处是没有写其他页面，所以放在AppDelegate）
#import "AppDelegate.h"
#import "YTKKeyValueStore.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSString *pathName = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
NSString *filePath = [pathName stringByAppendingPathComponent:@"flynn.db"];
YTKKeyValueStore *store = [[YTKKeyValueStore alloc] initWithDBWithPath:filePath];
NSString *tableName = @"user_table";
NSString *key = @"1";//tableName和key可以做一个全局的宏，这样不容易写错
NSDictionary *queryUser = [store getObjectById:key fromTable:tableName];
NSLog(@"其他页面打印存储结果: %@", queryUser);
return YES;
}
4、打印结果
2021-03-08 20:44:47.017347+0800 ytkKeyValueStore[7082:348678] 其他页面打印存储结果: {
age = 30;
id = 1;
name = flynn;
}
