UIPickerView完成按钮不起作用

Question

I have a UITextField on which I have put UIPickerView. When user click on textfield, pickerview will show up just like a keyboard. I am trying to remove the pickerview with the help of Done button in it's toolbar but it's not doing so. Below is my code.

I have tried looking for ideas online, but didn't solve my purpose. Can anyone help me out with this, like what I am missing here.

-(void)pickerViewSetUp
{
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    CGFloat screenWidth = screenRect.size.width;
    NSLog(@"%f %f",screenWidth,screenHeight);

    _myPickerView = [[UIPickerView alloc]init];
    _myPickerView.delegate = self;
    _myPickerView.dataSource = self;

    UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, screenWidth, 44)];
    toolBar.barStyle = UIBarStyleBlackTranslucent;
    UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(hidePicker)];
    UIBarButtonItem *flexible = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
    [toolBar setItems:[NSArray arrayWithObjects:flexible,doneButton, nil]];
    [_myPickerView addSubview:toolBar];
}

-(void)hidePicker
{
    [_toss resignFirstResponder];
}

- (void)textFieldDidBeginEditing:(UITextField *)textField;
{
    if (textField == _toss)
    {
        _toss.inputView = _myPickerView;
    }
}

Solution

As a temp solution I have used a tap gesture, so when a user selects from picker view and taps on screen, pickerview is gone. Below is my code: Inside viewDidLoad

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hidePicker)];
[self.view addGestureRecognizer:tap];

and then

-(void)hidePicker
{
    [_toss resignFirstResponder];
}

I would still love to solve the mystery behind done button not hiding my pickerview.

Answer 1

Try calling

[self.view endEditing:YES];

in -(void)hidePicker

Answer 2

Not getting what you actually want to do. Just to remove that picker you Can You try :

[_myPickerView removeFromSuperview];

in -(void)hidePicker
