UIDatePicker Automation using KIF dateChangedAction not called - ios

Question

I'm automating date selection on UIDatePicker using KIF. I added the accessibility label and set the target for the picker if the date changes.
Ref: http://bit.ly/140ICwo
+(id) changeDate: (NSDate *) myDate
{
[s addStep:[KIFTestStep stepToEnterDate:myDate ToDatePickerWithAccessibilityLabel:#"datePicker"]];
[self wait:s timeInSeconds:3];
[s addStep:[KIFTestStep stepToTapViewWithAccessibilityLabel:#"Done" traits:UIAccessibilityTraitButton]];
return s;
}
- (void) ViewDidLoad
{
...
datePicker.maximumDate = lastAvailableDate;
datePicker.date = (dateValue ? dateValue : [NSDate date]);
[datePicker addTarget:self action:#selector(dateChangedAction:)
forControlEvents:UIControlEventValueChanged];
self.datePicker.accessibilityLabel = #"datePicker";
self.footerLabel.accessibilityLabel = #"datelabel";
}
- (IBAction)dateChangedAction:(id)sender
{
[dateValue release];
dateValue = [datePicker.date retain];
dateCell.detailTextLabel.text = [[[self class] sharedFormatter] stringFromDate:dateValue];
[self setDateTitleText:[[[self class] sharedFormatter] stringFromDate:dateValue]];
}
The Picker rotates and stops at the given date however the "dateChangedAction" function is not getting called, hence the label which displays the selected date is not getting updated.
If I run the app with out KIF everything works fine. Also I tried to manually select a date when running KIF to check it it updates the label but it seems like the UI gets frozen and I cannot click any UI controls.
Looks like the problem is related to this posting

Any help is very much appreciated.

I run into the same problem you're just missing
[picker sendActionsForControlEvents:UIControlEventValueChanged];
to trigger the dateChangedAction callback,
in other words try this:
+ (id)stepToEnterDate:(NSDate*)date ToDatePickerWithAccessibilityLabel:(NSString*)label
{
NSString *description=[NSString stringWithFormat:#"Enter date to Date picker with accessibility label '%#'",[date description]];
return [self stepWithDescription:description executionBlock:^(KIFTestStep *step, NSError **error)
{
UIAccessibilityElement *element = [[UIApplication sharedApplication] accessibilityElementWithLabel:label];
KIFTestCondition(element, error, #"View with label %# not found", label);
if(!element)
{
return KIFTestStepResultWait;
}
UIDatePicker *picker = (UIDatePicker*)[UIAccessibilityElement viewContainingAccessibilityElement:element];
KIFTestCondition([picker isKindOfClass:[UIDatePicker class]], error, #"Specified view is not a picker");
[picker setDate:date animated:YES];
// trigger the UIControlEventValueChanged in case of event listener
[picker sendActionsForControlEvents:UIControlEventValueChanged];
return KIFTestStepResultSuccess;
}];
}
