Question

Hi I am developing an iphone app where I have populated a uipickerview and it works great with one uitextfield. But I have 6 uitextfield I need to populate and I am using the same uipickerview for each UItextfield.

I have working the Ipickerview loaded with array objects and it pops up when each field is touched. The problem is with the code below the UItextfields share the same data from the picker.

I can not figure out how to code so each field gets it own data from the UIPickerView row.
What Am I doing wrong? Any coding suggestions?

Thanks

@implementation BestViewController

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

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

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

-(void)pickerView:(UIPickerView *)thePickerview didSelectRow:(NSInteger)row inComponent:      (NSInteger)component 
{ 
    uitextfield1.text = [list objectAtIndex:row];   
    utitextfield2.text = [list objectAtIndex:row];
}



- (void)viewDidLoad {

[super viewDidLoad];

    uitextfield1.inputView = pickerView; 
uitextfield2.inputView = pickerView;

list = [[NSMutableArray alloc] init];   
[list addObject:@"a"];
[list addObject:@"b"];
    [list addObject:@"c"];  
    [list addObject:@"d"];
}

You need to get hold of the current first responder and set its text property rather than explicitly setting a particular text field.

So,

-(void)pickerView:(UIPickerView *)thePickerview didSelectRow:(NSInteger)row inComponent:      (NSInteger)component 
{ 
    // textFields is an NSArray holding each of the textfields that are using the picker as an input view
    for (UITextField textField in textFields)
    {
        if ([textField isFirstResponder])
        {
            textField.text = [list objectAtIndex:row];
            break;
        }
    }    
}

There may be a more elegant way to find the current first responder, this is off the top of my head. textFields could possibly be an IBOutletCollection, but I haven’t used those myself so I can’t speak with much authority.
