Question

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;
}

Answer 1

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.

Answer 2

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
