//1.创建数据库 指定数据库的路径 一次
NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject]stringByAppendingPathComponent:@"huanzhelast.sqlite"];
_dataBase = [FMDatabase databaseWithPath:path];
// NSLog(@"%@",path);
self.dbProvinceMarray = [NSMutableArray array];

BOOL success = [_dataBase open];
if (success) {

//2.创建表 字段 ()
// id 主键 fullname 全称 name 名字 treePath 树路径 parent 父类
//2.创建表
NSString *str = @"CREATE TABLE IF NOT EXISTS t_huanzhelast(id integer PRIMARY KEY AUTOINCREMENT , fullname text NOT NULL,name text NOT NULL, parent text NOT NULL,treePath text NOT NULL);";

//保存到数据库的省市区 数据
-(void)saveData{

3://查询语句 省份
-(void)selectProvince{
NSString *strSql = @"SELECT * FROM t_huanzhelast where parent = 0;";
//查询语句 执行的方法
FMResultSet *set = [_dataBase executeQuery:strSql];
while ([set next]) {
NSString *parent = [set stringForColumn:@"parent"];
[self.dbProvinceMarray addObject:parent];
// NSString *[email protected]"0";
// if ([str isEqualToString:parent]) {
// [self.dbProvinceMarray addObject:parent];
//
// NSString *name = [set stringForColumn:@"name"];
// [self.dbProvinceName addObject:name];
// NSLog(@"name==%@",name);
// }
}
NSLog(@"==sp%zd",self.dbProvinceMarray.count);
