plist的创建与读取

项目中用到地址的pickview，后台给的数据是直接给了个db文件，当时没想太多直接按db文件来弄model

#import "ShengModel.h"
#import "ChengShiModel.h"

@implementation ShengModel


- (id) initWithDictionary:(NSDictionary*) dic
{
    self=[super init];
    
    if (self)
    {
        
        self.m_id = [dic objectForKey:@"id"];
        self.m_name = [dic objectForKey:@"name"];
        
        self.m_datas = [NSMutableArray array];
        //        NSString *upid =[dic objectForKey:@"upid"];
        
        NSMutableArray *cityAry = [self searchAddressInPTCCdbWithupid:[dic objectForKey:@"id"]];
        
        for (NSDictionary *d in cityAry) {
            ChengShiModel *model=[[ChengShiModel alloc] initWithDictionary:d];
            [self.m_datas addObject:model];
        }
        
        //
        
        
    }
    return self;
}



//查找数据库
-(NSMutableArray *)searchAddressInPTCCdbWithupid:(NSString *)upid{
    
    NSMutableArray *array = [NSMutableArray array];
    //查找数据库
    NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"ptcc" ofType:@"db"];
    FMDatabase* database = [ FMDatabase databaseWithPath: resourcePath ];
    if ( ![ database open ] )
    {
        return nil;
    }
    
    NSString *fuzzyQuerySql = [NSString stringWithFormat:@"SELECT * FROM address WHERE upid = '%@'", upid];
    //
    FMResultSet* resultSet = [ database executeQuery:fuzzyQuerySql];
    
    // 逐行读取数据
    while ( [ resultSet next ] )
    {
        
        
        NSString *name = [resultSet stringForColumn:@"name"];
        NSString *blueID = [resultSet stringForColumn:@"id"];
        NSString *upid = [resultSet stringForColumn:@"upid"];
        
//        NSLog(@" name = %@, id = %@, upid = %@", name, blueID, upid);
        NSMutableDictionary *dic = [NSMutableDictionary dictionary];
        [dic setObject:name forKey:@"name"];
        [dic setObject:blueID forKey:@"id"];
        [dic setObject:upid forKey:@"upid"];
        
        [array addObject:dic];
        
    }
    
    return array;
    
}

结果发现太耗时了，每次都要查表，点地址栏太快会没来得及查完显示不完全，就自己做了张plist表果然直接读取快了很多

先把db文件中的数据都读取出来，然后写进去

 listArray = [NSMutableArray array];
    
    [self searchShengAddressInTestdbWithupid:@"0"];
    NSLog(@"count = %ld", listArray.count);
    
    
    //开始制作plist表
    //获取本地沙盒路径
    NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    //获取完整路径
    NSString *documentsPath = [path objectAtIndex:0];
    NSLog(@"str = %@", documentsPath);
    NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"xxlAreaList.plist"];
    
    
    NSMutableDictionary *usersDic = [[NSMutableDictionary alloc ] init];
    //设置属性值
    [usersDic setObject:listArray forKey:@"list"];
    [usersDic setObject:@(listArray.count) forKey:@"total"];

    
    [usersDic writeToFile:plistPath atomically:YES];
    NSLog(@"制表成功");
