-(void)openDatase{  
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);  
    NSString *documentsDirectory = [paths objectAtIndex:0];  
    self.databasePath = [documentsDirectory stringByAppendingPathComponent:@"weightCal.sqlite"];  
    if (sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) {  
        NSLog(@"Database Successfully Opened ");  
    } else {   
        NSLog(@"Error in opening database ");  
    }  
}

-(void)dealloc{
    sqlite3_close(database);
    [super dealloc];
}


-(void)copyDatabase {
    BOOL success;
    NSFileManager *fileManager=[NSFileManager defaultManager];
    NSError *error;
    NSArray *paths= NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory=[paths objectAtIndex:0];
    NSString *writablePath = [documentsDirectory stringByAppendingPathComponent:@"test.sqlite"];
    success = [fileManager fileExistsAtPath:writablePath];
    if(success) {
       return;
    }
    NSString *defaultPath=[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"test.sqlite"];
    success=[fileManager copyItemAtPath:defaultPath toPath:writablePath error:&error];
    if(!success){
       NSAssert1(0,@"Failed to create writable database file with message '%@' .",[error localizedDescription]);
    }
}

Declare following teo variable in .h:

sqlite3 *database; 
NSString *databasePath;
