Add UIButton to UIDatePicker

I have a UITextField that I set the inputView to a UIDatePicker so that when the UITextField is pressed, the UIDatePicker appears instead of the keyboard. I would also like to add a toolbar with a Next button so that the user can easily navigate to the next field, but I'm not sure how to do that as I already change the view to a UITextField to get the UIDatePicker. Here is the code used when loading the view:

- (void)viewDidLoad
{
self.datePicker = [[UIDatePicker alloc] init];
self.datePicker.datePickerMode = UIDatePickerModeDate;
[self.datePicker addTarget:self action:@selector(datePickerValueChanged) forControlEvents:UIControlEventValueChanged];
issue.inputView = self.datePicker;
}

      

Suggestions for adding a Next button to a toolbar on top of it?

Create a view to use as the inputAccessoryView text field. This view should contain your buttons (eg "Undo", "Previous").

Here's the code:

if (keyboardToolbar == nil) {
keyboardToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 44)];
[keyboardToolbar setBarStyle:UIBarStyleBlackTranslucent];

UIBarButtonItem *extraSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];

UIBarButtonItem *next = [[UIBarButtonItem alloc] initWithTitle:@"Next" style:UIBarButtonItemStyleDone target:self action:@selector(switchToNextField:)];

[keyboardToolbar setItems:[[NSArray alloc] initWithObjects: extraSpace, next, nil]];
}

issue.inputAccessoryView = keyboardToolbar;

datePicker = [[UIDatePicker alloc] init];
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker addTarget:self action:@selector(datePickerValueChanged:) forControlEvents:UIControlEventValueChanged];

issue.inputView = datePicker;

      



And in your switchToNextField method, just create nextField as firstResponder using [nextTextField to becomeFirstResponder];

You can create a view and then put all the user interface elements in it.

@property (nonatomic,strong) UIPopoverController *popoverControllerBirthday;

      

add above to your .h file and sync to .m @synthesize popoverControllerBirthday;

also change your @synthesize datePicker;

to@synthesize datePicker=_datePicker;

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{

    if (textField==self.yourtextfield) {
        UIViewController* popoverContent = [[UIViewController alloc] init]; //ViewController

        UIView *popoverView = [[UIView alloc] init];   //view
        popoverView.backgroundColor = [UIColor blackColor];

        _datePicker=[[UIDatePicker alloc]init];//Date picker
        _datePicker.frame=CGRectMake(0,0,320, 216);
        _datePicker.datePickerMode = UIDatePickerModeDate;
        [_datePicker setMinuteInterval:5];
        [_datePicker setTag:10];
        [popoverView addSubview:_datePicker];



        UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        [button addTarget:self
                   action:@selector(result)
         forControlEvents:UIControlEventTouchUpInside];
        [button setTitle:@"Next" forState:UIControlStateNormal];
        button.frame = CGRectMake(0, 220, 320, 45);
        UIColor *titleColor = [UIColor whiteColor];
        [button setTitleColor:titleColor forState:UIControlStateNormal];
       // UIImage *doneButtonImage = [UIImage imageNamed:@"create event button.png"]; choose a button background if you ahve one
        [button setBackgroundImage:doneButtonImage forState:UIControlStateNormal];
        [popoverView addSubview:button];


        popoverContent.view = popoverView;
        popoverControllerBirthday = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
        popoverControllerBirthday.delegate=self;

        CGRect myFrame =textField.frame;
        myFrame.origin.x = 200;// your coordinates change it as you wish
        myFrame.origin.y = 195;

        [popoverControllerBirthday setPopoverContentSize:CGSizeMake(320, 265) animated:NO];
        [popoverControllerBirthday presentPopoverFromRect:myFrame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

        return NO; // tells the textfield not to start its own editing process (ie show the keyboard)
    }
    else{
         return YES;
    }

}
//handle your result call next uitextfield in your case
-(void) result 
{
    //in result method you can get date using datepicker.date
    if (self.popoverControllerBirthday)
         {
             [self.popoverControllerBirthday dismissPopoverAnimated:NO];
              self.popoverControllerBirthday = nil;
    }

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setTimeStyle:NSDateFormatterNoStyle];
    [dateFormatter  setDateFormat:@"M d yyyy"];
    NSString *parseDatePickerDAte =[dateFormatter stringFromDate:_datePicker.date]; // your string that is choosen at datepicker
   // self.textfield.text = parseDatePickerDAte ; set this to your textfield if you want

   //google this dont remember exact code for that, just changing your textfield to desired one
   [self.nexttextfield becomesFirstResponder];



}

You can use SMDatePicker instead of UIDatePicker. It will create a custom view with UIToolbar and UIDatePicker. You can easily customize the toolbar with the buttons you need. Check out the sample project.
