remove/hide rows outside minimum/maximum date range of UIDatePicker?

Question

I have a UIDatePicker with set minimum and maximum dates. I\'m wondering if there is a way to hide the rows of the columns for the dates/times that are either befor

Answer 1

Using the minimumDate and maximumDate APIs will behave as you've explained - still show the dates but not allow selecting them. There is currently no way to hide those dates that are out of the provided range, however I do have a solution for you.

Instead of using the min and max dates with a UIDatePicker, you can generate an array of all of the NSDates you want to show to the user, and use a UIPickerView to present them to the user. I've done exactly this for one of my own apps.

self.datePicker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 162)];
self.datePicker.dataSource = self;
self.datePicker.delegate = self;
//...

#pragma mark - UIPickerView Data Source and Delegate

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
    return 1;
}

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
    return [self.availableDates count];
}

- (CGFloat)pickerView:(UIPickerView *)pickerView rowHeightForComponent:(NSInteger)component {
    return 28;
}

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view {
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
    label.font = [UIFont systemFontOfSize:20];
    label.textColor = [UIColor blackColor];

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    dateFormatter.dateFormat = @"EEE, MMMM d";

    label.text = [dateFormatter stringFromDate:self.availableDates[row]];

    [label sizeToFit];

    return label;
}
