Hi I am developing small IOS application in which I am using actionsheet. So my problem is like this when I clicked outside the actionsheet it is closing my actionsheet it is calling - (void) actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex method even though I am not clicking any button of actionsheet. It is returning lastindexof action sheet button. So how to avoid this. Any solution? I tried with -(void)actionSheet:(UIActionSheet *)action didDismissWithButtonIndex:(NSInteger)buttonIndex
But still same result.
I write the time picker by my self instead UIActionSheet in iOS8:
date = [NSDate date];
timePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 44, 0, 0)];
timePicker.datePickerMode = UIDatePickerModeDateAndTime;
timePicker.hidden = NO;
timePicker.date = date;
displayFormatter = [[NSDateFormatter alloc] init];
[displayFormatter setTimeZone:[NSTimeZone localTimeZone]];
[displayFormatter setDateFormat:#"MM月dd日 EEE HH:mm"];
formatter = [[NSDateFormatter alloc] init];
[formatter setTimeZone:[NSTimeZone localTimeZone]];
[formatter setDateFormat:#"YYYY-MM-dd HH:mm:ss"];
startDisplayTimeString = [displayFormatter stringFromDate:timePicker.date];
startTimeString = [formatter stringFromDate:timePicker.date];
NSTimeInterval interval = 24*60*60*1;
NSDate *endDate = [[NSDate alloc] initWithTimeIntervalSinceNow:interval];
endDisplayTimeString = [displayFormatter stringFromDate:endDate];
endTimeString = [formatter stringFromDate:endDate];
[_startTimeLabel setText:startDisplayTimeString];
[_endTimeLabel setText:endDisplayTimeString];
[pickerViewPopup dismissWithClickedButtonIndex:1 animated:YES];
NSDateFormatter *dateFormatter =[[NSDateFormatter alloc] init];
[dateFormatter setTimeZone:[NSTimeZone localTimeZone]];
[dateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 64)];
pickerToolbar.tintColor = [UIColor whiteColor];
[pickerToolbar sizeToFit];
UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStyleBordered target:self action:#selector(cancelBtnPressed:)];
[cancelBtn setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:

When you tap outside of the UIActionSheet, UIKit performs the same action as if you had tapped the cancel button. The buttonIndex that is sent in - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex is the cancel button index. There isn't a way to know if the user tapped outside of your UIActionSheet, by default. If you want this functionality you will have to code your own custom action sheet or handle the outside tap as a cancel tap.
I am using selectedRowInComponent method to get the presently selected row on component with index 0 but it is always returning 0. I have checked it in
NSLog("%d",[pickerview selectedRowInComponent:0]);
I have initialized the picker as I am using picker view programmatically. Please Suggest.
I hope this code will help you.I am using it in my project its working perfect.
Call this function it ViewDidLoad
[self loadFirstPicker];
Below is function to make UIpicker which shows only time. (And Save in text feild)
-(void)loadFirstPicker
{
UIDatePicker *picker = [[UIDatePicker alloc] init];
picker.autoresizingMask = UIViewAutoresizingFlexibleWidth;
picker.datePickerMode = UIDatePickerModeTime;
[picker addTarget:self action:#selector(dueDateChanged:) forControlEvents:UIControlEventValueChanged];
CGSize pickerSize = [picker sizeThatFits:CGSizeZero];
picker.frame = CGRectMake(0.0, 250, pickerSize.width, 460);
picker.backgroundColor = [UIColor blackColor];
checkEveryTextFeild.inputView = picker;
//[self.view addSubview:picker];
//[picker release];
// Create done button in UIPickerView
UIToolbar* mypickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 220, 56)];
mypickerToolbar.barStyle = UIBarStyleBlackOpaque;
[mypickerToolbar sizeToFit];
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
[barItems addObject:flexSpace];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(pickerDoneClicked)];
[barItems addObject:doneBtn];
[mypickerToolbar setItems:barItems animated:YES];
checkEveryTextFeild.inputAccessoryView = mypickerToolbar;
}
This Function getting the time from picker and setting it to textFeild
-(void) dueDateChanged:(UIDatePicker *)sender {
NSDateFormatter* dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:#"HH:mm:ss"];
//[dateFormatter setTimeStyle:NSDateFormatterNoStyle];
checkEveryTextFeild.text = [dateFormatter stringFromDate:[sender date]];
NSDate *currentDate = [NSDate date];
NSLog(#"%#",currentDate);
NSLog(#"Picked the date %#", [dateFormatter stringFromDate:[sender date]]);
}
you might want to try setting both of them. the second line will retrieve the pickerview that the class detects:
[filterPicker selectRow:selectedPickerIndex inComponent:0 animated:NO];
[self pickerView:filterPicker didSelectRow:selectedPickerIndex inComponent:0];
self.personInfoPicker.delegate = self;
self.personInfoPicker.dataSource = self;
[self.personInfoPicker reloadAllComponents];
I´m using the UIDatePicker in a form but the problem is that when I select the date and time, the time in the text field is 5 hours after the time showed in the picker. I've read that there's a bug in date picker but I don't know how to solve this. I need to show the time of Mexico. I've tried doing this but nothing change.
datePicker.calendar = [NSCalendar autoupdatingCurrentCalendar];
datePicker.timeZone = [NSTimeZone localTimeZone];
datePicker.locale = [NSLocale currentLocale];
Can anyone help me with this??? XD
Thank you guys!!
If you aren't using it already, I'd suggest doing:
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateStyle:NSDateFormatterMediumStyle];
[df setTimeStyle:NSDateFormatterMediumStyle];
NSString *stringToDisplay = [df stringFromDate:myDateObject];
NSDateFormatter should take care of any time zone issues for you. You can read more here.
o this: this will help you

How would you do that?
I have a form with a UITextField. When I click in it I would like to display a UIDatePicker instead of the default Keyboard that pops-up by default? Note that there are also other elements on my form.
I think this is a more official way to do this:
UIDatePicker *datePicker = [[[UIDatePicker alloc] init] autorelease];
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker addTarget:self action:#selector(datePickerValueChanged:) forControlEvents:UIControlEventValueChanged];
datePicker.tag = indexPath.row;
textField.inputView = datePicker;
in .h
UIDatePicker *datePicker;
NSDate *date;
UIToolbar *keyboardToolbar;
in ViewDidLoad:
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 *accept = [[UIBarButtonItem alloc] initWithTitle:#"Accept" style:UIBarButtonItemStyleDone target:self action:#selector(closeKeyboard:)];
[keyboardToolbar setItems:[[NSArray alloc] initWithObjects: extraSpace, accept, nil]];
}
self.txtDate.inputAccessoryView = keyboardToolbar;
datePicker = [[UIDatePicker alloc] init];
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker addTarget:self action:#selector(datePickerValueChanged:) forControlEvents:UIControlEventValueChanged];
self.txtDate.inputView = datePicker;
- (void)datePickerValueChanged:(id)sender{
date = datePicker.date;
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"dd/MM/YYYY"];
[self.txtDate setText:[df stringFromDate:date]];
}
in storyboard add to txtDate -> EditingDidEnd
- (IBAction)establishHour:(id)sender{
hour = hourPicker.date;
NSDateFormatter *hf = [[NSDateFormatter alloc] init];
[hf setDateFormat:#"HH:MM"];
[self.txtHour setText:[hf stringFromDate:hour]];
}
Sets the keyboard as DatePicker and created a toolbar with a button to accept the selection.
I've converted Johan Kool's answer into swift if anyone would like it. I placed the code in viewDidLoad.
let datePicker = UIDatePicker()
datePicker.datePickerMode = UIDatePickerMode.Date
datePicker.addTarget(self, action: "datePickerValueChanged:", forControlEvents: UIControlEvents.ValueChanged)
textField.inputView = datePicker
(IBAction)estableceHora:(id)sender{
Hora = horaPicker.date;
NSDateFormatter *hf = [[NSDateFormatter alloc] init];
[hf setDateFormat:#"HH:MM"];
[self.txtHora setText:[hf stringFromDate:Hora]];
}
Added in .h files :
UIViewController <UIPickerViewDelegate, UIPickerViewDataSource>
Added in .m files :
{
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
pTxtDate.text = [NSString stringWithFormat:#"%#",
[df stringFromDate:[NSDate date]]];
NSLog(#"pTxtDate.text %#",pTxtDate.text);
[df release];
[self.view addSubview:pTxtDate];
[pTxtDate release];
DatePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 250, 325, 300)];
DatePicker.datePickerMode = UIDatePickerModeDate;
DatePicker.hidden = NO;
DatePicker.date = [NSDate date];
[DatePicker addTarget:self
action:#selector(LabelChange:)
forControlEvents:UIControlEventValueChanged];
[self.view addSubview:DatePicker];
[DatePicker release];
}
- (void)LabelChange:(id)sender {
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
pTxtDate.text = [NSString stringWithFormat:#"%#",
[df stringFromDate:DatePicker.date]];
}

maybe you should get rid of the UIActionSheet and do it like I did for another question.
UIDatePicker pop up after UIButton is pressed
