Can I click tableview cell show picker?

Question

I establish a tableview , but I want to click direct cell show the picker to select.

Then the selected value will show in the cell label component.

But I had try to labelName.text = picker. or call picker in the didSelectRowAtIndexPath . It's not showing the picker.

my code is below

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

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

        }
        cell.motTableTitleLabel.text = [tableDatasAry  objectAtIndex:indexPath.row];

        if( indexPath.row == 0)
        {

      }
        else if ( indexPath.row == 1)
        {
            myLb = [ [UILabel alloc ] initWithFrame:CGRectMake(_motTableView.frame.size.width -50 , 0.0, 70.0, 40.0) ];

                 // -------  I expect click the picker value will show in myLb label
            myLb.text = @"picker will show value"; 

            [cell addSubview:myLb];

        }



        return cell;
    }


    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

    switch (indexPath.row) {


            case 0:
                break;

            case 1:
                 // -------- I had try put settingPickeProperty in here or viewdidload
                [self settingPickeProperty];

                break;
          default:
                break;
        }
    }

    #pragma mark -  settting picker datas
    -(void) settingPickeProperty
    {
        picker = [[UIPickerView alloc] initWithFrame:CGRectZero];

        picker  .delegate = self;
        picker  .dataSource = self;
        [ picker  setShowsSelectionIndicator:YES];

        // -------if i use textfield the picker had correct show. but i want to click        cell show the picker, I don't know how to set  xxxx = picker;
        _pickertf.inputView =  picker  ;

        UIToolbar*  mypickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 56)];
        mypickerToolbar.barStyle = UIBarStyleDefault;
        [mypickerToolbar sizeToFit];

        NSMutableArray *barItems = [[NSMutableArray alloc] init];

        UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc]         initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
       [barItems addObject:flexSpace];

        UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:@"done" style:UIBarButtonItemStyleBordered target:self action:@selector(pickerDoneClicked)];


        [barItems addObject:doneBtn];
        [mypickerToolbar setItems:barItems animated:YES];
        // ------ if use textfield had correct...
        _pickertf.inputAccessoryView = mypickerToolbar;

    }


    -(void)pickerDoneClicked
    {
        NSLog(@"Done Clicked");

    }

    - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
    {
        return 1;
    }


    - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:        (NSInteger)component
    {
        return [titleAry count];
    }


    - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
    {
        return [titleAry objectAtIndex:row];
    }


    - (void) pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
    {

    }

It's my code offer every reference.

How to achieve click tableview cell to show the picker then select picker value show in myLb?

at didSelect Method you have selected row index. so you can put code of open picker by select particular cell of table view. — Nitin Gohel, Mar 06 '14 at 06:56

@NitinGohel he is selecting the 2nd row. See `switch (indexPath.row)` — Himanshu Joshi, Mar 06 '14 at 07:03

You are not adding the pickerView anywhere.

If you want to add in the current view, just use

picker = [[UIPickerView alloc] initWithFrame:CGRectZero];

picker.delegate = self;
picker.dataSource = self;
[picker setShowsSelectionIndicator:YES];
[self.view addSubView:picker];

If I set textfield . the picker will show when i click the textfield. ( _pickertf.inputView = picker ;) But If I will set on tableview cell when user click. I don't know how to set this part. And I had try to add [self.view addSubView:picker]; it's will show error. below: No visible @interface for 'UIView' declares the selector 'addSubView:' thanks – dickfala Mar 06 '14 at 07:14
What is the base class in which you are adding the picker? – Himanshu Joshi Mar 06 '14 at 07:15
the effect is click picker will show. not always show on the view. – dickfala Mar 06 '14 at 07:15
my base class is extends UIViewController – dickfala Mar 06 '14 at 07:16
So what is this **No visible @interface for 'UIView' declares the selector 'addSubView:'** ? – Himanshu Joshi Mar 06 '14 at 07:21
Did you used UIPicker `delegates` and `datasource` protocols? – Himanshu Joshi Mar 06 '14 at 07:22
yes, I have add protocols. If i try to use textfield, the picker will show when i click textfield. So the picker program maybe not problem. The problem is on _pickertf.inputView = picker ; here. If i use textfield , the picker is set _pickertf.inputview = picker. If I want to set click on the cell. I don't know how to set xxx = picker or other implement method. thank you~ – dickfala Mar 06 '14 at 07:26
_pickertf is my test textfield. – dickfala Mar 06 '14 at 07:31
So basically you want the selected value from picker in textfield? – Himanshu Joshi Mar 06 '14 at 07:35
NO.. I have a label in the tableview cell. I want to click tableview cell jump to picker . Then after select picker value click done. It's will show value in the label. TextField(_pickertf) just I try to know picker program is correct or not. – dickfala Mar 06 '14 at 07:39

According to my understanding, you need to show picker value in selected table cell label.

So following steps may help you if cells are constant; for example just three cells.

You just not need to dequeue the cell and then try to set the value.
