Showing a UIPickerView with UIActionSheet in iOS8 not working

Question

Showing a UIPickerView with UIActionSheet in iOS8 not working

The code works in iOS7, however it is not working in iOS8. I'm sure it is because UIActionSheet is deprecated in iOS8 and Apple recommends to use UIAlertController.

However, how to do it in iOS8? I should use UIAlertController?

iOS7:

iOS8:

EDIT:

My GitHub project solving the problem.

Answer 1

I write the time picker by my self instead UIActionSheet in iOS8:

date = [NSDate date];

timePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 44, 0, 0)];
timePicker.datePickerMode = UIDatePickerModeDateAndTime;
timePicker.hidden = NO;
timePicker.date = date;

displayFormatter = [[NSDateFormatter alloc] init];
[displayFormatter setTimeZone:[NSTimeZone localTimeZone]];
[displayFormatter setDateFormat:@"MM月dd日 EEE HH:mm"];

formatter = [[NSDateFormatter alloc] init];
[formatter setTimeZone:[NSTimeZone localTimeZone]];
[formatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"];

startDisplayTimeString = [displayFormatter stringFromDate:timePicker.date];
startTimeString = [formatter stringFromDate:timePicker.date];

NSTimeInterval interval = 24*60*60*1;
NSDate *endDate = [[NSDate alloc] initWithTimeIntervalSinceNow:interval];
endDisplayTimeString = [displayFormatter stringFromDate:endDate];
endTimeString = [formatter stringFromDate:endDate];

[_startTimeLabel setText:startDisplayTimeString];
[_endTimeLabel setText:endDisplayTimeString];

[pickerViewPopup dismissWithClickedButtonIndex:1 animated:YES];

NSDateFormatter *dateFormatter =[[NSDateFormatter alloc] init];
[dateFormatter setTimeZone:[NSTimeZone localTimeZone]];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 64)];
pickerToolbar.tintColor = [UIColor whiteColor];
[pickerToolbar sizeToFit];

UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelBtnPressed:)];

[cancelBtn setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                   [UIColor colorWithRed:253.0/255.0 green:68.0/255.0 blue:142.0/255.0 alpha:1.0],
                                   NSForegroundColorAttributeName,
                                   nil] forState:UIControlStateNormal];

UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];

UIBarButtonItem *titleButton;

float pickerMarginHeight = 168;


titleButton = [[UIBarButtonItem alloc] initWithTitle:@"title" style:UIBarButtonItemStylePlain target: nil action: nil];

[titleButton setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                     [UIColor colorWithRed:253.0/255.0 green:68.0/255.0 blue:142.0/255.0 alpha:1.0],
                                     NSForegroundColorAttributeName,
                                     nil] forState:UIControlStateNormal];

UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:@"OK" style:UIBarButtonItemStyleDone target:self action:@selector(setTimePicker)];

[doneBtn setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                 [UIColor colorWithRed:253.0/255.0 green:68.0/255.0 blue:142.0/255.0 alpha:1.0],
                                 NSForegroundColorAttributeName,
                                 nil] forState:UIControlStateNormal];

NSArray *itemArray = [[NSArray alloc] initWithObjects:cancelBtn, flexSpace, titleButton, flexSpace, doneBtn, nil];

[pickerToolbar setItems:itemArray animated:YES];

if(iPad){

    [pickerToolbar setFrame:CGRectMake(0, 0, 320, 44)];

    UIViewController* popoverContent = [[UIViewController alloc] init];
    popoverContent.preferredContentSize = CGSizeMake(320, 216);
    UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 216)];
    popoverView.backgroundColor = [UIColor whiteColor];
    [popoverView addSubview:timePicker];
    [popoverView addSubview:pickerToolbar];
    popoverContent.view = popoverView;
    popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
    [popoverController presentPopoverFromRect:CGRectMake(0, pickerMarginHeight, 320, 216) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

}else{

    timeBackgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, SCREEN_HEIGHT-300, 320, 246)];
    [timeBackgroundView setBackgroundColor:[UIColor colorWithRed:240/255.0 green:240/255.0 blue:240/255.0 alpha:1.0]];

    [timeBackgroundView addSubview:pickerToolbar];
    [timeBackgroundView addSubview:timePicker];

    [self.view addSubview:timeBackgroundView];}

Answer 2

From the reference for UIActionSheet:

UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.

My guess is your seeing exactly why.

The reference for UIAlertController doesn't have a similar disclaimer, but looking at its interface, my guess is Apple will add it before release.

My recommendation would be to just create a small view containing your picker and buttons and show and hide it as needed. It's not that hard to do and your not pushing interfaces beyond their intended uses.

UIActionSheet is depricated in iOS8. Use UIAlertController for iOS8 or later

UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"My Alert"
                            message:@"This is an action shhet."
                            preferredStyle:UIAlertControllerStyleActionSheet];

UIAlertAction* cameraAction = [UIAlertAction actionWithTitle:@"Take A Photo" style:UIAlertActionStyleDefault
                                    handler:^(UIAlertAction * action) {}];

UIAlertAction* galleryAction = [UIAlertAction actionWithTitle:@"From Gallery" style:UIAlertActionStyleDefault
                                                     handler:^(UIAlertAction * action) {}];

UIAlertAction * defaultAct = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel
                                                    handler:^(UIAlertAction * action) {}];

[alert addAction:cameraAction];
[alert addAction:galleryAction];
[alert addAction:defaultAct];

[self presentViewController:alert animated:YES completion:nil];

Try to use this action sheet simulation:

@interface UIViewController (ActionSheetSimulation)

-(UIView*) actionSheetSimulationWithPickerView:(UIPickerView*)pickerView withToolbar: (UIToolbar*)pickerToolbar;
-(void)dismissActionSheetSimulation:(UIView*)actionSheetSimulation;

@end


#import "UIViewController+ActionSheetSimulation.h"
