feting label time on the datepicker - ios

I am working with the UIdatepicker. I am fetching the time from the datepicker and showing the date on the label. Once i select the date it is shown on the label and datepicker is hidden away. Now i want that when i call the picker it should show me the selection bar of the datepicker on the date of the label which i selected previously selected on the datepicker.Code i am using is shown below:-
-(void)datepickershown:(UILabel *)time animated:(BOOL)animated
{
UIActionSheet *actionsheet = [[UIActionSheet alloc] initWithTitle:#"Select the Time" delegate:self cancelButtonTitle:nil destructiveButtonTitle:#"DONE" otherButtonTitles:Nil, nil];
pickdate = [[UIDatePicker alloc] initWithFrame:[actionsheet bounds]];
pickdate.hidden = NO;
//pickdate.date = [NSDate date];
pickdate.datePickerMode = UIDatePickerModeTime;
[pickdate addTarget:self action:#selector(changeDateInLabel:) forControlEvents:UIControlEventValueChanged];
[actionsheet addSubview:pickdate];
[actionsheet showInView:self.view];
[actionsheet setBounds:CGRectMake(0,0,320, 500)];
CGRect pickerRect = pickdate.bounds;
pickerRect.origin.y = -90;
pickdate.bounds = pickerRect;
}
- (IBAction)changeDateInLabel:(id)sender
{
NSLog(#"I Am Changing the values");
df = [[NSDateFormatter alloc] init];
df.timeStyle = NSDateFormatterShortStyle;
}
Image below can describe you more

use setDate:animated of UIDatePicker...
- (void)setDate:(NSDate *)date animated:(BOOL)animated
to convert your label.text to NSDate:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setFormatterBehavior:NSDateFormatterBehaviorDefault];
[dateFormatter setDateFormat:#"hh:mm"]; // depends on 12(hh) or 24(HH)
NSDate *yourDate = [dateFormatter dateFromString:label.text];

Displaying current default date in UIDatePickerr view

If I am selecting date from date picker view for current date, the time is also getting selected and displaying the current time, I want to separate in two different selection event
Here is my code snippet-
/* Button for displaying UIDatePicker view */
-(void) dueDateChanged:(UIDatePicker *)sender {
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd MMM, yyyy"];
self.lbl_StartDateValue.text = [dateFormatter stringFromDate:[sender date]];
self.planStartDate = [dateFormatter stringFromDate:[sender date]];
NSDate *date = [[NSCalendar currentCalendar] dateByAddingComponents:dateComponents toDate:[dateFormatter dateFromString:[dateFormatter stringFromDate:[sender date]]] options:0];
self.lbl_EndDateValue.text = [NSString stringWithFormat:#"End %#",[dateFormatter stringFromDate:date]];
self.planEndDate = [dateFormatter stringFromDate:date];
}
// Here I am not able to differentiate the selection of two picker view
-(void)onDoneButtonClick {
[self dueDateChanged:self.picker];
[self dueTimeChanged:self.picker];
[self.toolbar removeFromSuperview];
[self.picker removeFromSuperview];
[self.tempBackgroundView removeFromSuperview];
}
-(void) dueTimeChanged:(UIDatePicker *)sender {
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"hh:mm a"];
self.lbl_timeValue.text = [dateFormatter stringFromDate:[sender date]];
self.planAlarmtime = [dateFormatter stringFromDate:[sender date]];
}
do like , initially set the current date on your text field whenever user present the date picker
(IBAction)btn_calendar_event:(id)sender {
......
[self.toolbar sizeToFit];
[self.view addSubview:self.toolbar];
//if you want to show the default date as current date
self.picker.date = [NSDate date];
// set inital date on your textfield
[self dueDateChanged : self.picker];
}
if user pressed the done button then call this
-(void)onDoneButtonClick {
// call the method
[self dueDateChanged : self.picker];
[self.toolbar removeFromSuperview];
[self.picker removeFromSuperview];
[_txtf_birthDate resignFirstResponder];
}
finally change the YYYY format
-(void) dueDateChanged:(UIDatePicker *)sender {
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSLog(#"Picked the date %#", [dateFormatter stringFromDate:[sender date]]);
_txtf_birthDate.text = [dateFormatter stringFromDate:[sender date]];
}
Just set minimum data as your current date
[self.picker setMinimumDate:[NSDate date]];
also you will not select until you scroll Picker
if you want to show the default date as current date
self.picker.date = [NSDate date]
this is the code for UIDatepicker alloca and set current date
UIDatePicker *datepicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height-320, self.view.frame.size.width, 320)];
datepicker.date = [NSDate date];
[self.view addSubview:datepicker];

No known class method for selector 'datePicker'

I have searched similar questions here to help me solve mine, all in vain. I want the UItextField when clicked to pull up the UIDatePicker, then the user can select a date, and then set it in the UITextfield. However I keep getting an error for 'datePicker'. not sure what else I am supposed to do.
This is the part of my app that calls the datePicker
-(void)textFieldDidBeginEditing:(UITextField *)textField
{
[pd resignFirstResponder]; //the textField that you will set the selected date
datePicker = [[UIDatePicker alloc] init]; //declared uidatepicker component
pickerViewDate = [[UIActionSheet alloc] initWithTitle:#"Select the date!"
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0.0, 44.0, 0.0, 0.0)];
datePicker.datePickerMode = UIDatePickerModeDate; //set your spesific mode
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4];
[dateFormatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:#"en_US"]]; //or another LocaleIdentifier instead of en_US
[dateFormatter setDateFormat:#"dd.MM.yyyy"]; //desired format
[datePicker addTarget:self action:#selector(dateChanged) forControlEvents:UIControlEventValueChanged]; //the function would be fired when user change the date in datePicker
//now preparing the toolbar which will be displayed at the top of the datePicker
pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
pickerToolbar.barStyle=UIBarStyleBlackOpaque;
[pickerToolbar sizeToFit];
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(doneButtonClicked)]; //barbutton item is "DONE" and doneButtonClicked action will be fired when user clicks the button.
[barItems addObject:flexSpace]; // set the left of the bar
[pickerToolbar setItems:barItems animated:YES];
[pickerViewDate addSubview:pickerToolbar];
[pickerViewDate addSubview:datePicker];
[pickerViewDate showInView:self.view];
[pickerViewDate setBounds:CGRectMake(0,0,320, 464)]; //you can change the position
}
-(IBAction)dateChanged{
NSDateFormatter *FormatDate = [[NSDateFormatter alloc] init];
[FormatDate setLocale: [[NSLocale alloc]
initWithLocaleIdentifier:#"en_US"]];
[FormatDate setDateFormat:#"dd.MM.yyyy"];
pd.text = [FormatDate stringFromDate:[UIDatePicker datePicker]];
}
You're not going to be able to Google the cause of the errors in your code. You will need to figure it out, as your code is unique.
As #madmik3 points out, this line is wrong:
pd.text = [FormatDate stringFromDate:[UIDatePicker datePicker]];
That code is trying to call a UIDatePicker class method "datePicker", which doesn't make any sense.
What you probably want instead is:
pd.text = [FormatDate stringFromDate: [datePicker date]];
That code is asking your date picker object, in the variable datePicker, for it's date property (the current date set in the date picker.

How to Validate the Date of Birth IOS7

Hi in my application i have a registration form in my application and I'm validating all fields like email and phone number. But i want to validate this DOB in format like DD/MM/YY. I'm using else if condition checking for my validation i want do same for DOB
I'm validation with else if condition like this.
- (IBAction)send:(id)sender {
if ([self phonevalidate:[ph text]]!= 1){
UIAlertView *alert1 = [[UIAlertView alloc]initWithTitle:#"Message" message:#"pls enter valid 10 digit number" delegate:self cancelButtonTitle:#"ok" otherButtonTitles:nil, nil];
[alert1 show];
[alert1 release];
}
else if ([self validateEmail:[emd text]]!= 1){
UIAlertView *alert1 = [[UIAlertView alloc]initWithTitle:#"Message" message:#"pls enter valid email id" delegate:self cancelButtonTitle:#"ok" otherButtonTitles:nil, nil];
[alert1 show];
[alert1 release];
}
My validation function for phone.
-(BOOL)phonevalidate:(NSString *)phh
{
NSString *phoneRegex = #"[0-9]{10}";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:#"SELF MATCHES %#", phoneRegex];
return [phoneTest evaluateWithObject:phh];
}
I'm not using the UIDate Picker i have UITextfield for the DOB i want validate with UITextfield itself.Like the above i want to validate the DOB please tell me how to validate the DOB and check int else if condition.
Thanks.
EDITED:
Assume that b'date is
NSString *dateOfBirth = #"22/03/14";
And this is method for check b'date is valid or not ?
-(BOOL) isValidateDOB:(NSString *) dateOfBirth
{
NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateStyle:NSDateFormatterShortStyle];
[format setDateFormat:#"dd/MM/yy"];
NSDate *validateDOB = [format dateFromString:dateOfBirth];
if (validateDOB != nil)
return YES;
else
return NO;
}
In above method [format setDateStyle:NSDateFormatterShortStyle]; and setDateFormat is very important in your case:
Now you can check it as like,
if([self isValidateDOB:dateOfBirth])
{
// b"date is valid;
}
else
{
// b"date is not valid;
}
You can use UIDatePicker for this :
Initialize like this :
UIDatePicker datePicker = [[UIDatePicker alloc] init];
datePicker.datePickerMode = UIDatePickerModeDate;
datePicker.date = [NSDate date];
Then, set the inputView of your textField (the one that takes DOB as input) :
yourDOBtextField.inputView = datePicker;
Then, implement textFieldDidEndEditing: delegate method for UITextField:
- (void) textFieldDidEndEditing:(UITextField *)textField {
if (textField == yourDOBtextField) {
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = #"dd/MM/yy";
yourDOBtextField.text = [dateFormatter stringFromDate:datePicker.date];
[dateFormatter release];
}
}
That's it.
Let's try below codes:
NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"DD/MM/YY"];
NSDate *date = [dateFormatter dateFromString:#"12/12/2014"];
If (date)
{
NSLog(#"Valid date");
}

Getting date from the label onto the datepicker

I am working with the UIdatepicker. I am fetching the time from the datepicker and showing the date on the label. Once i select the date it is shown on the label and datepicker is hidden away. Now i want that when i call the picker it should show me the selection bar of the datepicker on the date of the label which i selected previously selected on the datepicker.Code i am using is shown below:-
-(void)datepickershown:(UILabel *)time animated:(BOOL)animated
{
UIActionSheet *actionsheet = [[UIActionSheet alloc] initWithTitle:#"Select the Time" delegate:self cancelButtonTitle:nil destructiveButtonTitle:#"DONE" otherButtonTitles:Nil, nil];
pickdate = [[UIDatePicker alloc] initWithFrame:[actionsheet bounds]];
pickdate.hidden = NO;
//pickdate.date = [NSDate date];
pickdate.datePickerMode = UIDatePickerModeTime;
[pickdate addTarget:self action:#selector(changeDateInLabel:) forControlEvents:UIControlEventValueChanged];
[actionsheet addSubview:pickdate];
[actionsheet showInView:self.view];
[actionsheet setBounds:CGRectMake(0,0,320, 500)];
CGRect pickerRect = pickdate.bounds;
pickerRect.origin.y = -90;
pickdate.bounds = pickerRect;
}
- (IBAction)changeDateInLabel:(id)sender
{
NSLog(#"I Am Changing the values");
df = [[NSDateFormatter alloc] init];
df.timeStyle = NSDateFormatterShortStyle;
}
As you want the datepicker to show the date you have already set on the label.
For this you need to use following method.
- (void)setDate:(NSDate *)date animated:(BOOL)animated
Pass the date whatever you have selected and is shown in the label.
try this
[self.datePicker setDatePickerMode:UIDatePickerModeDate];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"dd-MM-yyyy"];
if([dateFormat dateFromString:yourDateLabel.text])
{
NSDate *date = [dateFormat dateFromString:yourDateLabel.text];
[self.datePicker setDate:date];
}
hope this will work

UIDatePicker selected date does not appear

UIDatePickerView is working fine. It shows up, I can scroll through the dates, but for some reason my selectedOB.text keeps coming up as Todays date! No matter what date I choose, it shows as todays date!
I select this:
NSLog and the label shows up as:
Here is the code:
- (IBAction)selectDOB:(id)sender
{
UIActionSheet *selectBirthMY = [[UIActionSheet alloc] initWithTitle:#"Select Date of Birth" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"Select", nil];
[selectBirthMY setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
[selectBirthMY showInView:[UIApplication sharedApplication].keyWindow];
[selectBirthMY setFrame:CGRectMake(0, 100, 320, 500)];
}
- (void)willPresentActionSheet:(UIActionSheet *)actionSheet
{
UIDatePicker *pickerView = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 40, 320, 216)];
pickerView.datePickerMode = UIDatePickerModeDate;
[pickerView setMinuteInterval:15];
//Add picker to action sheet
[actionSheet addSubview:pickerView];
//Gets an array af all of the subviews of our actionSheet
NSArray *subviews = [actionSheet subviews];
[[subviews objectAtIndex:1] setFrame:CGRectMake(20, 265, 280, 46)];
[[subviews objectAtIndex:2] setFrame:CGRectMake(20, 317, 280, 46)];
}
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
UIDatePicker *DOBPicker = [[UIDatePicker alloc] init];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MMMM dd, YYYY"];
NSDate *pickedDOB = [DOBPicker date];
NSString *DOB = [dateFormatter stringFromDate:pickedDOB];
NSLog (#"This is DOB %#", DOB);
self.selectedDOB.text=DOB;
}
You are using two different instances of UIDatePicker. You need to use the same instance of datePicker to get the selected date
Make a property for datePicker
#property (nonatomic, strong) UIDatePicker *pickerView;
- (void)willPresentActionSheet:(UIActionSheet *)actionSheet
{
if(!self.pickerView){
self.pickerView = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 40, 320, 216)];
self.pickerView.datePickerMode = UIDatePickerModeDate;
[self.pickerView setMinuteInterval:15];
//Add picker to action sheet
[actionSheet addSubview:self.pickerView];
}
//Gets an array af all of the subviews of our actionSheet
NSArray *subviews = [actionSheet subviews];
[[subviews objectAtIndex:1] setFrame:CGRectMake(20, 265, 280, 46)];
[[subviews objectAtIndex:2] setFrame:CGRectMake(20, 317, 280, 46)];
}
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MMMM dd, YYYY"];
NSDate *pickedDOB = [self.pickerView date];
NSString *DOB = [dateFormatter stringFromDate:pickedDOB];
NSLog (#"This is DOB %#", DOB);
self.selectedDOB.text=DOB;
}
This is because you are allocating new instance of UIDatePicker in this method
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
So don't create new instance . Use already created datepicker instance .
Hope it helps you.
