I have a view containing a segmented controller and a UIDatePicker that only shows 24-h time. I want to be able to set different times depending on what the segmented control says. So "Mon" would correspond to one time, "Tue" to another and so on. I have this working. However, I also would like to animate the picker when the user changes button on the segmented controller. As of now I have in my action method linked to the segmented controller this:
[timePicker setDate:date animate:YES];
Where date is a NSDate formatted like so: HH:mm
As I said, it will change to the date but it will not animate the operation. Anyone knows why it doesn't animate?
BTW, although I have set the formatter to be "HH:mm" if I use NSLog to print it I still get the whole 1970-01-01 +02:00:00 string printed. I assume that the only HH:mm is sent to the datepicker anyway and that it is just NSLog that prints the whole thing?
EDIT: Here is the code for the actual view controller, and this is running SDK4
#import "FlipsideViewController.h"

[timePicker addTarget:self action:@selector(timePickerAction:) forControlEvents:UIControlEventValueChanged];
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"HH:mm"];
NSDate *sunnyDate = [df dateFromString: [times objectAtIndex:0]];
[df release];
[timePicker setDate:sunnyDate animated:NO];
}
