Display Done Button on Uipickerview

How to make an UIPickerView with a Done button?

Add this code to your viewDidLoad() instead of method

let picker: UIPickerView
picker = UIPickerView(frame: CGRectMake(0, 200, view.frame.width, 300))
picker.backgroundColor = .whiteColor()

picker.showsSelectionIndicator = true
picker.delegate = self
picker.dataSource = self

let toolBar = UIToolbar()
toolBar.barStyle = UIBarStyle.default
toolBar.isTranslucent = true
toolBar.tintColor = UIColor(red: 76/255, green: 217/255, blue: 100/255, alpha: 1)
toolBar.sizeToFit()

let doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItem.Style.done, target: self, action: #selector(self. donePicker))
let spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.flexibleSpace, target: nil, action: nil)
let cancelButton = UIBarButtonItem(title: "Cancel", style: UIBarButtonItem.Style.plain, target: self, action: #selector(self. donePicker))

toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
toolBar.userInteractionEnabled = true

textField1.inputView = picker
textField1.inputAccessoryView = toolBar

display done button on UIPickerview

You can use this code,

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(changeDateFromLabel:)];
toolBar.items = @[barButtonDone];
barButtonDone.tintColor=[UIColor blackColor];
[pickerView addSubview:toolBar];
//(or)pickerView.inputAccessoryView = toolBar;

and set button action method for changeDateFromLabel:

-(void)changeDateFromLabel:(id)sender
{
   [[your UI Element] resignFirstResponder];
}

Show a UIPickerView when a button is tapped

If you want to do it from Interface Builder then you can add UIPickerView in your storyBoard and initially hide that UIPickerView and when your button tapped show it.

If you want to do this by coding then you can try this.

Define this as global.

var toolBar = UIToolbar()
var picker  = UIPickerView()

Add below code inside your button tap action. I have added Done button in toolbar to dismiss picker.

Note : I write entire code in button action if you don't want to do that just write all code in viewDidLoad and write only these line in your button action self.view.addSubview(picker) and self.view.addSubview(toolBar)

@IBAction func YOUR_BUTTON__TAP_ACTION(_ sender: UIButton) {
    picker = UIPickerView.init()
    picker.delegate = self
    picker.dataSource = self
    picker.backgroundColor = UIColor.white
    picker.setValue(UIColor.black, forKey: "textColor")
    picker.autoresizingMask = .flexibleWidth
    picker.contentMode = .center
    picker.frame = CGRect.init(x: 0.0, y: UIScreen.main.bounds.size.height - 300, width: UIScreen.main.bounds.size.width, height: 300)
    self.view.addSubview(picker)
            
    toolBar = UIToolbar.init(frame: CGRect.init(x: 0.0, y: UIScreen.main.bounds.size.height - 300, width: UIScreen.main.bounds.size.width, height: 50))
    toolBar.barStyle = .blackTranslucent
    toolBar.items = [UIBarButtonItem.init(title: "Done", style: .done, target: self, action: #selector(onDoneButtonTapped))]
    self.view.addSubview(toolBar)
}

On Done button you can remove toolBar as well as PickerView.

@objc func onDoneButtonTapped() {
    toolBar.removeFromSuperview()
    picker.removeFromSuperview()
}

Delegate methods of UIPickerView

func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return 1
}
    
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return YOUR_DATA_ARRAY.COUNT
}
    
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    return YOUR_DATA_ARRAY[row]
}
    
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    print(YOUR_DATA_ARRAY[row])
}

Done Toolbar on UIPickerView

It seems like UIPickerView is not letting its children receive touch events. If you are showing this in conjunction with UITextField you can use it's inputView and inputAccessoryView to acheive the same. Alternatively you can create a top level container UIView to hold both toolbar and picker view like this:

    let picker = UIView(frame: CGRect(x: 0, y: view.frame.height - 260, width: view.frame.width, height: 260))

    // Toolbar
    let btnDone = UIBarButtonItem(barButtonSystemItem: .done, target: self, action: #selector(self.monthdoneButtonAction))
    let spaceButton = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
    let cancelButton = UIBarButtonItem(title: "Cancel", style: .plain, target: self, action: #selector(self.cancelClick))

    let barAccessory = UIToolbar(frame: CGRect(x: 0, y: 0, width: picker.frame.width, height: 44))
    barAccessory.barStyle = .default
    barAccessory.isTranslucent = false
    barAccessory.items = [cancelButton, spaceButton, btnDone]
    picker.addSubview(barAccessory)

    // Month UIPIckerView
    monthPicker = UIPickerView(frame: CGRect(x: 0, y: barAccessory.frame.height, width: view.frame.width, height: picker.frame.height-barAccessory.frame.height))
    monthPicker.delegate = self
    monthPicker.dataSource = self
    monthpickerData = ["January","February","March","April","May","June","July","August","September","October","November","December"]
    monthPicker.backgroundColor = UIColor.white
    picker.addSubview(monthPicker)

how to add done button on uipicker view

You can use this . first add UIView in your self.view. add UIPickerView and UIToolBar init. and bind IBAction method with UIBarButtonItem. Please check attach screenshot.

Maybe this will help you.

How do I confirm my selection in UIPickerView with a done button?

@objc func donePressed(_ sender: UIButton) {
        print("Done pressed")
        print(strings[pickerView!.selectedRow(inComponent: 0)])
}

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

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];
