Xcode Saving UIDatepicker to be displayed in a label - iphone

Question

The following code is to show my UIDatepicker:
- (IBAction)showActionSheet:(id)sender {
NSString *title = UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation) ? #"\n\n\n\n\n\n\n\n\n" : #"\n\n\n\n\n\n\n\n\n\n\n\n" ;
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:[NSString stringWithFormat:#"%#%#", title, NSLocalizedString(#"Please Select A Date", #"")]
delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:#"I've Made My Choice", nil];
[actionSheet showInView:self.view];
UIDatePicker *datePicker = [[[UIDatePicker alloc] init] autorelease];
datePicker.datePickerMode = UIDatePickerModeDate;
[actionSheet addSubview:datePicker];
}
It all works properly, but what I'd like to do is to display the users choice into a label which I have named " label1 ". Can anyone help? Thanks!
UPDATE:
Here is the updated code:
- (IBAction)showActionSheet:(id)sender {
NSString *title = UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation) ? #"\n\n\n\n\n\n\n\n\n" : #"\n\n\n\n\n\n\n\n\n\n\n\n" ;
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:[NSString stringWithFormat:#"%#%#", title, NSLocalizedString(#"Please Select A Date", #"")]
delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:#"I've Made My Choice", nil];
[actionSheet showInView:self.view];
UIDatePicker *datePicker = [[[UIDatePicker alloc] init] autorelease];
datePicker.datePickerMode = UIDatePickerModeDate;
[actionSheet addSubview:datePicker];
[datePicker addTarget:self
action:#selector(updateLabel:)
forControlEvents:UIControlEventValueChanged];
}
- (void)updateLabel:(id)sender {
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
label1.text = [NSString stringWithFormat:#"%#",[df stringFromDate:datePicker.date]];
[df release];
/* the following allows you to choose the date components
NSCalendar *calendar = [NSCalendar currentCalendar];
int hour = [[calendar components:NSHourCalendarUnit fromDate:[datePicker date]] hour];
int minute = [[calendar components:NSMinuteCalendarUnit fromDate:[datePicker date]] minute];
int year = [[calendar components:NSYearCalendarUnit fromDate:[datePicker date]] year];
int month = [[calendar components:NSMonthCalendarUnit fromDate:[datePicker date]] month];
int day = [[calendar components:NSDayCalendarUnit fromDate:[datePicker date]] day];
*/
}
That's for the .m , my .xib has the 'label' tied properly too :) just getting a (null) value whenever I choose my date :(

Answer 1

.h
#import <UIKit/UIKit.h>
#interface YourViewController : UIViewController {
IBOutlet UILabel *label1;
}
#property (nonatomic, retain) UILabel *label1;
#end
.m
#implementation YourViewController
#synthesize label1;
/*
All of your code goes here
*/
#end
Interface Builder
Also add the following to your showActionSheet:
[datePicker addTarget:self
action:#selector(updateLabel:)
forControlEvents:UIControlEventValueChanged];
This should update your label from datePicker:
-(void)updateLabel:(id)sender
{
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
label1.text = [NSString stringWithFormat:#"%#",[df stringFromDate:datePicker.date]];
[df release];
/* the following allows you to choose the date components
NSCalendar *calendar = [NSCalendar currentCalendar];
int hour = [[calendar components:NSHourCalendarUnit fromDate:[datePicker date]] hour];
int minute = [[calendar components:NSMinuteCalendarUnit fromDate:[datePicker date]] minute];
int year = [[calendar components:NSYearCalendarUnit fromDate:[datePicker date]] year];
int month = [[calendar components:NSMonthCalendarUnit fromDate:[datePicker date]] month];
int day = [[calendar components:NSDayCalendarUnit fromDate:[datePicker date]] day];
*/
}

Here I shows that UIDatePicker in UITableview cell.
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
// Make a new view, or do what you want here
UIDatePicker *pv = [[UIDatePicker alloc] initWithFrame:CGRectMake(0,185,0,0)];
[self.view addSubview:pv];
return NO;
}
If you are using UITableView, then use following in order to show UIDatePicker instead of keyboard.
if (0 == indexPath.row) {
cell.rightTextField.placeholder = #”Date”;
cell.rightTextField.text = [coAccident strDateTime];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
UIDatePicker *datePicker = [[UIDatePicker alloc]initWithFrame:CGRectMake(0, 0, 185, 0)];
[datePicker addTarget:self action:#selector(changeDateInLabel :) forControlEvents:UIControlEventValueChanged];
cell.rightTextField.inputView = datePicker;
}
- (IBAction)changeDateInLabel:(id)sender {
UIDatePicker * datePicker = (UIDatePicker*)sender;
CAccidentVO* coAccident = [m_arrVehicles objectAtIndex:1];
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
[coAccident setStrDateTime:[NSString stringWithFormat:#"%#",[df stringFromDate:datePicker.date]]];
[df release];
[m_tvVehicleDetails reloadData];
}
