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];

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;

UIScreen.mainScreen.bounds.size.width,
UIScreen.mainScreen.bounds.size.height)];
[simulatedActionSheetView setBackgroundColor:[UIColor clearColor]];
CGFloat pickerViewYpositionHidden = UIScreen.mainScreen.bounds.size.height + pickerToolbar.frame.size.height;
CGFloat pickerViewYposition = UIScreen.mainScreen.bounds.size.height -

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 prefferedstyleUIAlertControllerStyleActionSheet 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

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.
#define CONTENT_HEIGHT 478
- (void)initSheetWithWidth:(CGFloat)aWidth
{
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
UIAlertController *sheet = [UIAlertController alertControllerWithTitle:@"hack space" message:@"\n\n\n\n\n\n\n\n\n\n\n" preferredStyle:UIAlertControllerStyleActionSheet];
[sheet.view setBounds:CGRectMake(7, 0, aWidth, CONTENT_HEIGHT)]; // Kinda hacky
self.sheet = sheet;
} else {
UIActionSheet *sheet = [[UIActionSheet alloc] init];
self.sheet = sheet;
}
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, aWidth, CONTENT_HEIGHT)];
[view setBackgroundColor:[UIColor whiteColor]];
UIToolbar *toolbar = [[UIToolbar alloc]
initWithFrame:CGRectMake(0, 0, aWidth, 0)];
toolbar.barStyle = UIBarStyleDefault;
[toolbar sizeToFit];
[toolbar setItems:@[
[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(pickerSheetCancel)],
[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(pickerSheetDone)]
]];
UIDatePicker *picker = [[UIDatePicker alloc]
initWithFrame:CGRectMake(0, toolbar.bounds.size.height, aWidth, 0)];
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
UIAlertController *sheet = self.sheet;
[view addSubview:toolbar];
[view addSubview:picker];
[sheet.view addSubview:view];
} else {
UIActionSheet *sheet = self.sheet;
[sheet addSubview:toolbar];
[sheet addSubview:picker];
}
self.picker = picker;
}
- (void)showWithDate:(NSDate*)date {
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
// Reload and select first item
[self.picker setDate:date];
[self.parentViewController presentViewController:self.sheet animated:YES completion:nil];
} else {
UIActionSheet *sheet = self.sheet;
[self.sheet showInView:self.containerView];
// XXX: Kinda hacky, but seems to be the only way to make it display correctly.
[self.sheet
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!

You can use an UIAlertController to do this.
@IBAction func btnActionDate(_ sender: Any) {
let picker = UIPickerView(frame: CGRect(x: 0, y: 50, width: self.view.frame.size.width - 16.0, height: 150))
picker.delegate = self
picker.dataSource = self
// let message = "\n\n\n\n\n\n"
let alert = UIAlertController(title: "Title of Action Sheet", message: "", preferredStyle: UIAlertController.Style.actionSheet)
alert.isModalInPopover = true
picker.reloadAllComponents()
//Add the picker to the alert controller
alert.view.addSubview(picker)
// For setting height of Action sheet
let height:NSLayoutConstraint = NSLayoutConstraint(item: alert.view!, attribute: NSLayoutConstraint.Attribute.height, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 350)
alert.view.addConstraint(height)
let okAction = UIAlertAction(title: "Done", style: .default, handler: {
(alert: UIAlertAction!) -> Void in
let fetchedObj = picker.selectedRow(inComponent: 0)
})
alert.addAction(okAction)
let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
alert.addAction(cancelAction)
self.present(alert, animated: true, completion: nil)
}
Set the delegates & data source of pickerView like this
class MyViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource
set the delegate & datasource functions
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return arrayMonthData.count
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return arrayMonthData[row]
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
}
func pickerView(_ pickerView: UIPickerView, widthForComponent component: Int) -> CGFloat {
return self.view.frame.size.width - 16.0
}
func pickerView(_ pickerView: UIPickerView, rowHeightForComponent component: Int) -> CGFloat {
return 36.0
}
