Add a UIButton to UIDatePicker - ios

Question

I have a UITextField that I set the inputView to a UIDatePicker so that when the UITextField is pressed, instead of a keyboard, a UIDatePicker pops up. I would like to also add a toolbar with a 'Next' button on it so that the user could easily jump to the next field, but I am not sure how to do this as I am already altering a view on the UITextField to get the UIDatePicker. Here is the code used in 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 getting the 'Next' button added to a toolbar on top of it?

Answer 1

Create a view to use as the text field's inputAccessoryView. This view should contain your buttons (e.g. Next, Cancel, Previous).

Answer 2

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 make the nextField as the firstResponder using [nextTextField becomeFirstResponder];

You can create a view then put any UI elements inside of it.
#property (nonatomic,strong) UIPopoverController *popoverControllerBirthday;
add above to your .h file and sync it at .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 easy customise toolbar with necessary buttons. Take a look at example project.
