Showing a UIPickerView with UIActionSheet in iOS8

问题:

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.

回答1:

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.

回答2:

To achieve the same visual effect you can use ActionSheetPicker-3.0, that works with iOS 8.

Actually, it's not UIActionSheet anymore. But looks exactly the same, and that's why it works on iOS 8.

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];

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

[pickerToolbar setItems:itemArray animated:YES];

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];

Try to use this action sheet simulation:

I have faced the same issue and solved it by this way it will work in all ios version

In ios 8 apple has changed so many things i here faced one problem in my own project so , i just want to provide the solution in replacement of UIActionsheet.

in ios 8 UIActionsheet deprecated as well its delegate methods also deprecated. Instead of that UIAlertController with prefferedstyle
UIAlertControllerStyleActionSheet is used. you can check this thread as well:

https://developer.apple.com/library/ios/documentation/Uikit/reference/UIActionSheet_Class/index.html

This example will work both in ios 8 and previous version of it.

in .h file declare this variable

@interface demoProfileForBuyer{
 UIActionSheet *ac_sheet_fordate;
 UIToolbar *pickerToolBar_fordate;

 UIDatePicker *optionPickerDate;
 UIAlertController *alertController;
}

in .m file

- (void)viewDidLoad
{

    [super viewDidLoad];
    pickerToolBar_fordate = [[UIToolbar alloc] initWithFrame:CGRectMake(-8, 0, 320, 44)];

    pickerToolBar_fordate.barStyle = UIBarStyleBlack;
    [pickerToolBar_fordate sizeToFit];

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

    UIBarButtonItem *doneBtnDate = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(pickerViewDoneBirthday)];

I have the same problem with you, showing a UIPickerView with UIActionSheet is not working in iOS 8. Because UIActionSheet is deprecated and Apple recommends to use UIAlertController. So we should round to wind.

I wrote some code to resolve my case. I hope it can help you.

         setBounds:CGRectMake(0, 0,
                              self.containerView.frame.size.width,
                              sheet.frame.size.height - CONTENT_HEIGHT)];

        // Reload and select first item
        [self.picker setDate:date];

        [UIView animateWithDuration:0.25 animations:^{
            [self.sheet
             setBounds:CGRectMake(0, 0,
                                  self.containerView.frame.size.width,
                                  sheet.frame.size.height)];
        }];
    }
}

I think it's all to fix this issue. Happy coding!
