具有多个TextField的动态UIPickerView

Question

I am using UIPickerView with UITextField . It is working when I use only one UITextField . What I want is to use multiple TextField for one dynamic pickerview .

- (void)viewDidLoad
{
[super viewDidLoad];

picker = [[UIPickerView alloc] init];
picker.dataSource = self;
picker.delegate = self;
self.transitTF.inputView = picker;
self.theData = @[@"one",@"two",@"three",@"four"];
}

-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
return self.theData.count;
}

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

-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
return self.theData[row];
}

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
self.transitTF.text = self.theData[row];
[self.transitTF resignFirstResponder];
}

This is what I use with one textField only.

Any help will be appreciated. Thanks.

Add tag property for each UITextField . In this case self.pickerView.inputView.tag you may use to find which textfield is using in current moment and you may fill picker with correct values
