How to hide UIPickerView in uitextfield?

Question

I created a UITextField and I set this inputview a pickerview. If I click into the textfield the pickerview is showing, but if I don't want to change the pickerview value, I tried to click on the view to dismiss pickerview, but its not working... I set textfield inputview in viewDidLoad():

picker = [[UIPickerView alloc] init];
picker.dataSource = self;
picker.delegate = self;
self.pickerTF.inputView = picker;

pickerTF is an UITextfield and picker is an UIPickerView.

I tried to use these methods to dismiss pickerview:

-(BOOL)textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder];
return true;
}
-(BOOL)disablesAutomaticKeyboardDismissal{
return NO;
}

I have already edited .h file:

@interface MyViewController : UIViewController <UIPickerViewDataSource, UIPickerViewDelegate, NetworkManagerDelegate, UITextFieldDelegate>
