//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];

self.dbProvinceName = [NSMutableArray array];

BOOL success = [_dataBase open];

if (success) {

NSLog(@"创建数据库成功!");

//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);";

if ([_dataBase executeUpdate:str]) {

NSLog(@"表创建成功!");

}else{

NSLog(@"创建表失败!");

}

}else{

NSLog(@"创建数据库失败!");

}

2:

//保存到数据库的省市区 数据

-(void)saveData{

for (int i=0; i<_searchplaceArray.count; i++) {

NSString *fullname=[[_searchplaceArray objectAtIndex:i] objectForKey:@"fullName"];

NSString *treePath=[[_searchplaceArray objectAtIndex:i] objectForKey:@"treePath"];

NSString *name=[[_searchplaceArray objectAtIndex:i] objectForKey:@"name"];

// NSNumber *parent1=[[_searchplaceArray objectAtIndex:i] objectForKey:@"parent"];

// NSInteger parent=[parent1 integerValue];

NSString *parent=[[_searchplaceArray objectAtIndex:i] objectForKey:@"parent"];

BOOL success = [_dataBase executeUpdate:@"INSERT INTO t_huanzhelast(fullname, name, parent,treePath) VALUES(?,?,?,?);",fullname,name,parent,treePath];

if (success) {

// NSLog(@"添加成功!");

}else{

NSLog(@"添加失败!");

}

}

[self selectProvince];

}

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 *str=@"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);
