iOS7 and UIActionSheet with Time Picker - ios

Question

I had an iOS6 app that used the following code to create a UIActionSheet with a Time Picker:
- (void)willPresentActionSheet:(UIActionSheet *)actionSheet
{
pickerView = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 40, 320, 216)];
//Configure picker...
[pickerView setMinuteInterval:5];
[pickerView setTag: 4];
[pickerView setDatePickerMode:UIDatePickerModeTime];
//Add picker to action sheet
[actionSheet addSubview:pickerView];
//Gets an array of all of the subviews of our actionSheet
NSArray *subviews = [actionSheet subviews];
[[subviews objectAtIndex:1] setFrame:CGRectMake(20, 266, 280, 46)];
[[subviews objectAtIndex:2] setFrame:CGRectMake(20, 317, 280, 46)];
}
It worked like a charm until I tried it in iOS7, it always crashes when I click the input field that pops up the action sheet. Here is the code behind the input field:
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
selectedTag = textField.tag;
// the input field that needs to show the actionsheet has tag 1.
if (selectedTag == 1) {
UIActionSheet *asheet = [[UIActionSheet alloc] initWithTitle:#"Select a time:"
delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil
otherButtonTitles:#"Select", nil];
[asheet showInView:[self.view superview]];
[asheet setFrame:CGRectMake(0, 110, 320, 500)];
textField.userInteractionEnabled = NO;
}
textField.userInteractionEnabled = YES;
}
When the app craches, I get the following message:

Answer 1

If you want a datepicker to be presented while clicking the textfield, you can directly present the datepicker. Make the datepicker as your textfield's inputview.
pickerView = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 40, 320, 216)];
//Configure picker...
[pickerView setMinuteInterval:5];
[pickerView setDatePickerMode:UIDatePickerModeTime];
[dateTextField setInputView:pickerView];

Answer 2

Try this..
[asheet showInView:self.view];
