Objective c 身份证传输问题

这似乎是一件很简单的事情，但我不知道怎么做

目前，我有一个居住在各大洲的rootView：

守则：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}

// Configure the cell.

    cell.accessoryType=UITableViewCellAccessoryDisclosureIndicator;
    //Continent is the class. continents is an array to store data
    Continent *cont=[self.continents objectAtIndex:[indexPath row]]; 
    cell.textLabel.text=cont.continentName;
    return cell;
    }

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
Continent *cont=[self.continents objectAtIndex:[indexPath row]];
SelectedContinent* selectedContinent=[[SelectedContinent alloc] initWithNibName: @"SelectedContinent" bundle: nil];

//NSLog(@"%@",cont.continentName);
[self.navigationController pushViewController: selectedContinent animated: YES];
[selectedContinent setTitle:cont.continentName];
[selectedContinent setContinentID:cont.continentID];
[selectedContinent release];
}

我用nib文件创建了一个新的viewcontroller。给了他桌面视图。现在我需要从SQLite文件填充国家。我创建了一个DBAccess类，该类应该执行所有数据库操作，并且为每个大陆编写了一个特殊的方法。然后我想到写很多方法是愚蠢的想法，而普遍的方法来到了世界：

-(NSMutableArray*)getTheCountriesEurope:(int)continentID
{
NSMutableArray* euCountriesArray=[[[NSMutableArray alloc]init]autorelease];
NSString* sqlContinents = [NSString stringWithFormat:
                   @"SELECT countries.countryID,countries.countryName\
                   FROM countries\
                   WHERE countries.relativeToContinentID=%i"
                   ,continentID];
/*const char* sqlContinents="SELECT countries.countryID,countries.countryName\
FROM countries\
WHERE countries.relativeToContinentID=?";*/
sqlite3_stmt *statement;
int sqlResult = sqlite3_prepare_v2(database, sqlContinents, -1, &statement, NULL);
if ( sqlResult== SQLITE_OK)
{
    while (sqlite3_step(statement) == SQLITE_ROW)
    {
        Country *countryObj = [[Country alloc] init];
        char *countryName = (char *)sqlite3_column_text(statement, 1);
        countryObj.countryID = sqlite3_column_int(statement, 0);
        countryObj.countryName = (countryName) ? [NSString stringWithUTF8String:countryName] : @"";
        [euCountriesArray addObject:countryObj];
        NSLog(@"%@",countryObj.countryName);
        [countryObj release];
    }
    sqlite3_finalize(statement);
}
else
{
    NSLog(@"Problem with the database:"); 
    NSLog(@"%d",sqlResult);
}
return euCountriesArray;

 }

无论如何，这个方法也有问题，我被告知要实现int-sqlite3\u-bind\u-intsqlite3\u-stmt*，int，int；方法也一样

嗯，目前我的问题是，我无法从RootViewController类中捕获continentID值，我需要它将该值作为参数提供给方法

这样分配countryID是否正确

在RootViewController中。如果是，那么如何获得该变量的值

当我推另一个视图时，我只看到标题，至少它显示正确

求救

在推送视图之前，需要指定值

[SelectedContinental设置标题：cont.Continental名称]； [SelectedContinental设置Continental ID:cont.Continental ID]； [self.navigationController pushViewController:selected:YES]

 [selectedContinent setTitle:cont.continentName];
 [selectedContinent setContinentID:cont.continentID];
