How to dismiss a UIPicker that is connected to a UITextField

Question:

I have a UITextField, and when pushed a UIPickerView comes up to choose a value. How do I get the UIPickerView to dismiss once a value is chosen. Someone in another thread told me to resignFirstResponder the textfield, but my code isn't working. Any ideas? NOTE: I have two text fields and UI Pickers, that's why I have the 'if' 'else' statement.

- (BOOL)textFieldShouldReturn:(UITextField *)textField { if (textField == self.ageTextField) { [ageTextField resignFirstResponder]; [agePickerView removeFromSuperview]; return YES; } else { [relationshipTextField resignFirstResponder]; [relationshipPickerView removeFromSuperview]; return YES; } }

Answer1:

Try the following code which may solve your problem.

- (BOOL)textFieldShouldReturn:(UITextField *)textField { if (textField == self.ageTextField) { [ageTextField resignFirstResponder]; } else { [relationshipTextField resignFirstResponder]; } [pickerView removeFromSuperview]; return YES; }

or resign your keyboard on following method of UIPickerView.

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

Answer2:

Please try resigning the UITextField in UIPickerViewDelegate method as follows.

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { [self.ageTextField resignFirstResponder]; pickerView.hidden = YES; //Show the pickerview again when you neeed it }

Answer3:

Implement the UIPickerViewDelegate protocol and implement the following method:

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