UiPickerView change font color according data
- by Fulkron
I'm using a pickerView with multiple components related to several fields in a Database (CoreData).
Is it possible to change the fontcolor for a specific component according the presence of data in the DB ?
For example the field in the DB is null the component font color should be RED otherwise black.
Any help will be appreciated !

==================
Thanks Kenny,
I have to apply to a single UIPicker only. So I', returning the view parametere (without modificatiosn). The result is all the pickers show empty rows.
Thanks for help !
Here you will find the code fragment:
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view {
if (pickerView == tipoPk){
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100,30)];
label.textColor = [UIColor redColor];
switch (component) {
case PK_Tipo:
label.text = [tipoArray objectAtIndex:row]];
break;
case PK_Settore:
label.text = [settoreArray objectAtIndex:row]];
break;
default:
break;
}
return label;
}
else {
return view; // <==== return view for non related pickerviews , but no rows shown
}
}
