pod 'CyhCoredataManager'

1.创建一个数据库，名字是创建的coredata的文件名字 [[cyhCoredtaDB coredataDBShare] createCoredataDB:@"coredataModel"];

2.添加数据

[cyhCoredtaDB inserDataWith_CoredatamodelClass:[DataModel class] CoredataModel:^(DataModel * model) {

    model.num = model01.num;
    model.name = model01.name;

} Error:^(NSError *error) {

   }'

3.查询数据

[cyhCoredtaDB selectDataWith_CoredatamoldeClass:[DataModel class] where:@"num = 100" Alldata_arr:^(NSArray *coredataModelArr) {

    [coredataModelArr enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
       DataModel * model = obj;
        NSLog(@"条件查询：%d==%@",model.num,model.name);
    }];
    
} Error:^(NSError *error) {

   }'

4.更改数据

[cyhCoredtaDB updataDataWith_CoredatamoldeClass:[DataModel class] where:@"num = 100" result:^(DataModel * model){

    model.num = 10;
    
} Error:^(NSError *error) {

  }];

5.删除数据

[cyhCoredtaDB deleteDataWith_CoredatamoldeClass:[DataModel class] where:@"num = 100" result:^(BOOL isResult) {

    NSLog(@"0失败1成功：%d",isResult);
} Error:^(NSError *error) {
    
}];
