UITableView all'interno UIPickerView in iOS

Question

mi colpisce in un problema in cui ho bisogno di attuare un multiplo selettore di selezione del tipo così per questo scopo sto facendo questo:

caratFromPicker = [[UIPickerView alloc] init]; 
    caratTable = [[UITableView alloc]initWithFrame:caratFromPicker.frame style:UITableViewStylePlain]; 
    caratTable.delegate = self; 
    caratTable.dataSource = self; 
    caratTable.bounces = YES; 

    UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(done)]; 
    UIToolbar *toolBar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, self.view.frame.size.height-caratFromPicker.frame.size.height-50, self.view.frame.size.width, 50)]; 
    [toolBar setBarStyle:UIBarStyleBlackOpaque]; 
    NSArray *toolbarItems = [NSArray arrayWithObjects:doneButton, nil]; 
    [toolBar setItems:toolbarItems]; 
    price1.inputView = caratFromPicker; 
    price1.inputAccessoryView = toolBar; 
    [caratFromPicker setDataSource: self]; 
    [caratFromPicker setDelegate: self]; 
    caratFromPicker.showsSelectionIndicator = YES;//loadFromPicker 
    [caratFromPicker addSubview:caratTable]; 

e implementato i delegati UITableView come:

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{ 
    return 1; 
} 

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ 
    return [caratFromArray count]; 
} 

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

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

    tableView.separatorStyle = UITableViewCellSeparatorStyleNone; 

    cell.textLabel.text = [caratFromArray objectAtIndex:indexPath.row]; 

    return cell; 
} 

ecco lo screenshot della stessa:

ma il mio problema è che non sono in grado di scorrere la Tableview a guarda i prossimi valori.

Puoi provare a utilizzare metodo delegato UIPicker:

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)theView{ 
    return YourTableView; 
} 

Per impostare tableView come la vista per la fila.
