How to hide a UIPickerView when the user make its choice

Question

I've created a custom UIPickerView with the following code

UIPickerView *picker =[[UIPickerView alloc] initWithFrame:CGRectMake(139,50,161,30)];
    picker.delegate=self;
    picker.showsSelectionIndicator=YES;
    picker.hidden=NO;

    [self.view addSubview:picker];

Now I want to hide the pickerView when the user make its choice of a row simply with

picker.hidden=YES;

Now: 1) How can I recognize the choice of the user and then hide the unuseful pickerview? 2) Can I show the choice in a TextField? with @"choice"?

I'm using a UIPickerView as the inputView for a TextField (thus replacing the onscreen keyboard). I use the following delegate to dismiss the view.

#pragma mark - UIPickerViewDelegate
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
    // Code logic
    [[self view] endEditing:YES];
}

Add this line where you have created picker

picker.delegate = self;

your callback

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
    picker.hidden=YES;
}

when I add this line: no visible @interface for 'UIPickerView' declares the selector "addTarget:action...' I've declared the picker in a function. How can I solve? – TheInterestedOne Dec 13 '12 at 11:36
I've declared picker in the .h as a uipickerview and remove it from the function to do not hide the istance variable declared in .h, but he problem remains – TheInterestedOne Dec 13 '12 at 11:44
@AlessandroBava Sorry was confused with date picker. Edited – Inder Kumar Rathore Dec 13 '12 at 11:46
and so itisn't possible to do that in this way? – TheInterestedOne Dec 13 '12 at 11:49

use the delegate method of UIPickerView like bellow..

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

        yourTextField.text = [yourArray objectAtIndex:row];
        thePickerView.hidden = YES;

    }

Also you can take one UIButton and hide this with action event of UIButton.

You can use UINavigationBar and Barbutton with cancel and Done text upon it.

You can refer the following link

Objective C implementing a UIPickerView with a "Done" button

no, I don't want to add buttons to my view. I want to automatically hide when the user makes its choice :) – TheInterestedOne Dec 13 '12 at 11:30
How will you recognise whether user selected the right selection or not? – Shashank Kulshrestha Dec 13 '12 at 11:31
just double tap on the selected row – TheInterestedOne Dec 13 '12 at 11:33

I'm using a UIPickerView as the inputView for a TextField (for replacing the standard keyboard). I use the ResignFirstResponder (TextField method) to dismiss the view.

In XCode 12.2 you could use:

thePickerView.isHidden = true
