UIPickerview done button not working, even its not calling selector method

Question

I am creating UIPickerView programatically and added a custom button, when the user pressed the button, the picker will not display. But when I pressed the button, it didn't even call its selector method. I know this question have many answers on this website, but it didn't solved my problem.

-(void) funtion
{
self.myPickerView = [[UIPickerView alloc]init];
self.myPickerView.dataSource = self;
self.myPickerView.delegate = self;
self.myPickerView.showsSelectionIndicator = YES;
self.myPickerView.frame = CGRectMake(0, 417, 320, 151);
[self.myPickerView setBackgroundColor:[UIColor whiteColor]];

UIToolbar *toolBar= [[UIToolbar alloc] initWithFrame:CGRectMake(0,0,320,44)];
[toolBar setBarStyle:UIBarStyleBlackOpaque];
UIBarButtonItem *barButtonDone = [[UIBarButtonItem alloc] initWithTitle:@"Done"
                                                                  style:UIBarButtonItemStyleBordered
                                                                 target:self
                                                                 action:@selector(donePressed:)];
toolBar.items = [[NSArray alloc] initWithObjects:barButtonDone,nil];
barButtonDone.tintColor=[UIColor blackColor];


[self.myPickerView addSubview:toolBar];

[self.view addSubview:self.myPickerView];

}

-(void)donePressed:(id)sender
{
      [self.myPickerView endEditing:YES];
}

Answer 1

Add toolbar as inputAccessoryView to the text field,

// Tool bar

UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,35)];
pickerToolbar.barStyle = UIBarStyleDefault;

// Bar button

UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(pickerDoneButtonTapped:)];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];

[pickerToolbar setItems:@[flexSpace,doneButton]];

self.selectedLockerTextFiled.inputAccessoryView = pickerToolbar;
self.selectedLockerTextFiled.inputView = picker;

Answer 2

for example I add this

Step-1

Create the One UIPicker,UItextField and NSArray for load the details

@interface ViewController ()<UITextFieldDelegate,UIPickerViewDataSource,UIPickerViewDelegate>
{

UITextField *myTextField;
UIPickerView *myPickerView;
NSArray *pickerArray;
}

@end

Step-2

on your ViewDidLoad call the picker method like

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self addPickerView];
}

Step-3

create the picker, textfield and done button

-(void)addPickerView{
pickerArray = [[NSArray alloc]initWithObjects:@"Chess",
               @"Cricket",@"Football",@"Tennis",@"Volleyball", nil];
myTextField = [[UITextField alloc]initWithFrame:
               CGRectMake(10, 100, 300, 30)];
myTextField.borderStyle = UITextBorderStyleRoundedRect;
myTextField.textAlignment = NSTextAlignmentCenter;
myTextField.delegate = self;
[self.view addSubview:myTextField];
[myTextField setPlaceholder:@"Pick a Sport"];
myPickerView = [[UIPickerView alloc]init];
myPickerView.dataSource = self;
myPickerView.delegate = self;
myPickerView.showsSelectionIndicator = YES;
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc]
                               initWithTitle:@"Done" style:UIBarButtonItemStyleDone
                               target:self action:@selector(done:)];
UIToolbar *toolBar = [[UIToolbar alloc]initWithFrame:
                      CGRectMake(0, self.view.frame.size.height-
                                 myPickerView.frame.size.height-50, 320, 50)];
[toolBar setBarStyle:UIBarStyleBlackOpaque];
NSArray *toolbarItems = [NSArray arrayWithObjects:
                         doneButton, nil];
[toolBar setItems:toolbarItems];
myTextField.inputView = myPickerView;
myTextField.inputAccessoryView = toolBar;

}

Step-4

if user press the Done Button resign the picker

-(void)done:(id)sender
{

[myTextField resignFirstResponder];
}

Step-5

PickerView Delegate methods

#pragma mark - Picker View Data source
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView{
return 1;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView
numberOfRowsInComponent:(NSInteger)component{
return [pickerArray count];
}

#pragma mark- Picker View Delegate

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:
(NSInteger)row inComponent:(NSInteger)component{
[myTextField setText:[pickerArray objectAtIndex:row]];
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:
(NSInteger)row forComponent:(NSInteger)component{
return [pickerArray objectAtIndex:row];
}

here I attached the sample project

Sample Output like

Update

if you are used the button hidden the pickerview use this

-(void)donePressed:(id)sender
{
  [self.myPickerView removeFromSuperview];

}

when you pressed the button call this method

[self funtion];

Answer 3

Add done button like this:-

UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
doneButton.frame = CGRectMake(0, 0, 40, 50);
[doneButton addTarget:self action:@selector(donePressed:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButtonDone = [[UIBarButtonItem alloc] initWithCustomView:logoButton];
toolBar.items = [[NSArray alloc] initWithObjects:barButtonDone,nil];
barButtonDone.tintColor=[UIColor blackColor];
[self.myPickerView addSubview:toolBar];
