The problem is that after picking date from UIDatePicker the "Ok" button of UIAlertView is disabled.I tried ,but no luck.
-(BOOL)alertViewShouldEnableFirstOtherButton:(UIAlertView *)alertView
should be called whenever we type anything in textfield,but when date is entered it's not getting called,but if i type anything from keyboard,its ok then.

The problem is you are not calling it to validate again..After values get inserted you should write this line to call validation..
[alertText sendActionsForControlEvents:UIControlEventEditingChanged];
in this method of yours..

I have made an app which is an Customized Alarm App. The UILocalNotification should invoke at the time selected by me in UIDatePicker, but is is not invoking at correct timing. For example, I selected the time as 2:00PM for the alarm, so the notification will invoke between 2:00PM and 2:01PM... but not sure when... it is giving me a delay of random time. In my UITableView you can see that it is the description displayed is also comes wrong. I know I am from India so it showing GMT timings, but can it could be corrected?

[dateComps setMinute:[timeComponents minute]];
**[dateComps setSecond:00];**
NSDate *itemDate = [calendar dateFromComponents:dateComps];
localNotification.fireDate = itemDate;
just keep in mind, the date from datepicker comes aligned with GMT. you have to convert to your own timezone by yourself. this could be the issue in your case.
I think the problem here has to do with the NSDatePicker returning the seconds of the current time along with the selected time. You need to strip the seconds from the date returned by the NSDatePicker and use that for your alarm and local notification.
NSDate *selectedDate = [datePicker date]; // you don't need to alloc-init the variable first
NSCalendar *cal = [NSCalendar currentCalendar];
NSDateComponents *dc = [cal components: (NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:selectedDate];
selectedDate = [cal dateFromComponents:dc];
// now you have an NSDate with zero seconds for your alarm
You should get much better accuracy on your notifications, but I don't think they're guaranteed to be exactly on the split second.
hi friend i have to make date application
i have groped tableview.i have one section and two row
when my application start i am showing default date on both cell on first cell i was showing today day+1 and on nextcell i am showing today day+6 they i can see but
- (id)init
{
[super initWithStyle:UITableViewStyleGrouped];

[dateComponents setDay:1];
app.selectionData.fromDateSelected = [gregorian dateByAddingComponents:dateComponents toDate:todaysDate options:0];
[dateComponents release];
[gregorian release];
//this is for 6day
NSDate *todaysDate1 = [NSDate date];

app.selectionData.toDateSelected = [gregorian1 dateByAddingComponents:dateComponents1 toDate:todaysDate1 options:0];
[dateComponents1 release];
[gregorian1 release];
return self;
}
but know i want if
the first cell selected date is changed from date pickerview and second cell date is less than the first cell selected date then change the second cell date automatically to first cell selected date+5 please help me how to solve it what the change i have to do in my code wher i am show by default this for once time on this this is my code on run time
this code i writemin my firstview controller class where i am show this date when my application start
in tableviewcellrowAtindexpath

}
if ([indexPath row] == 1 && [indexPath section] == 1)

this is code od dateview where i put my datepicker from here i selected date
- (void)viewDidLoad
{
// if(datePicker != nil && [datePicker retainCount] > 0)
// {
// [datePicker release];
//
// datePicker = nil;
//}

// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
-(void)DateChangeForFinalPayMent{
if ([selectionData type] == 0)
[selectionData setFromDateSelected:[datePicker date]];
else
[selectionData setToDateSelected:[datePicker date]];
// [super viewWillDisappear:animated];
}
I wrote an example project for you that does this
Basically - look at the delegate method of the picker view controller.
It sends back a new date - and from that date you can calculate the second date and reload your table view.
This is the code to get date from datepicker. 1st select the date & then select the cell you need to update.
NSString *dateString = nil;
-(void)DateChangeForFinalPayMent:(id)sender {
NSLocale *usLocale = [[[NSLocale alloc]initWithLocaleIdentifier:#"en_US"] autorelease];
NSDate *pickerDate = [self.datePicker date];
NSString *selectionString = [[NSString alloc] initWithFormat:#"%#", [pickerDate descriptionWithLocale:usLocale]];
NSLog(#"string =%#",selectionString);
dateString = selectionString;
[selectionString release];
}
On selecting the cell Perform this operation
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
selectedIndex = indexPath.row;
NSArray *array = [NSArray arrayWithObject:indexPath];
[tablview reloadRowsAtIndexPaths:array withRowAnimation:UITableViewRowAnimationFade];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//some condition over here
if(selectedIndex == indexPath.row)
cell.textLabel = dateString;
//some condition over her
}
You use this code according to your implementation..
How do i solve the problem where i got 2011-07-21 15:55:01 +0000 , but the timing is off by 4 hr, how do i remove the +0000? And I want the format to be Eg. Friday 12 June 2011 1:30 PM

I am using the above mentioned Calendar API. In CalendarTestViewController.m class we are getting the date. Now I have declared a global variable nsstring type and I want to use that date into another new class by using global variable. I have tried this a number of times but unable to get the output. If anyone know how can I use the selected date by using Calendar API, then please give me some solution.
Thanks in advance.
CODE
- (void)calendarView:(KLCalendarView *)calendarView tappedTile:(KLTile *)aTile{
NSLog(#"Date Selected is %#",[aTile date]);
str=(NSString *)[aTile date];
}
NSLog(#"str:%#",str);
glbdate1 = (NSString *)[aTile date];
NSLog(#"glbdate1:%#",glbdate1);
}
//I have declared the glbdate1 variable globally in app delegate file and i have made the new class calenderview
//I want to display the date in textfield by using global variable. Here is code in calenderview
-(void)viewWillAppear:(BOOL)animated {
if ([glbdate1 length] != 0)
{
from.text = glbdate1;
}
}
You have to convert the NSDate to NSString as follows,
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-mm-dd HH:mm:ss"];
NSString *dateString=[dateFormatter stringFromDate:date];
Then the same NSString value can be converted to NSDate as,
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-mm-dd HH:mm:ss"];
NSDate *dateFromString=[dateFormatter dateFromString:dateString];
-(BOOL)isDateinEventArray:(NSString*)iDateString{
//NSString *searchText = lblDate.text;
NSMutableArray *searchArray = [[NSMutableArray alloc] init];
for (ToDo *todoObj in appDelegate.todoArray)
{
NSString *date = todoObj.startDate;
[searchArray addObject:date];
}
if ([searchArray count] > 0) {
for (NSString *sTemp in searchArray)
{
NSRange titleResultsRange = [sTemp rangeOfString:iDateString
options:NSCaseInsensitiveSearch];
if (titleResultsRange.length > 0)
[copyListOfItems addObject:sTemp];
}
[searchArray release];
searchArray = nil;
}
if ([copyListOfItems count] > 0) {
return TRUE;
}else{
return FALSE;

You can set the frame of a picker view.
Instead of
age = [[UIPickerView alloc] init];
Use
UIPickerView *picker = [[UIPickerView alloc] initWithFrame:<Your frame>];
or
[picker setFrame:<your frame>];
Using this you can use multiple picker views.
Keep an identifier to both so that you can handle the delegates.
