在iOS8中显示与UIPickerView的UIActionSheet不起作用
该代码适用于iOS7，但它在iOS8中不起作用。我确定这是因为UIActionSheet在iOS8中被弃用，而Apple建议使用UIAlertController。
但是，如何在iOS8中做到这一点？我应该使用UIAlertController？
IOS 7：
iOS8上：
编辑：
从UIActionSheet的参考：
UIActionSheet不是设计为子类，也不应该为其层次结构添加视图。如果您需要提供比UIActionSheet API提供的更多自定义的工作表，您可以创建自己的工作表并使用presentViewController以模态方式呈现它：animated：completion：。
我的猜测是你确切看到了原因。
UIAlertController的参考没有类似的免责声明，但看看它的界面，我的猜测是Apple会在发布前添加它。
我的建议是创建一个包含选择器和按钮的小视图，并根据需要显示和隐藏它。这并不难做到并且你没有推动超出预期用途的界面。
要获得相同的视觉效果，您可以使用适用于iOS 8的ActionSheetPicker-3.0。
实际上，它不再是UIActionSheet了。但看起来完全一样，这就是它适用于iOS 8的原因。
我在iOS8中用自己的UIActionSheet编写时间选择器：
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];}
UIActionSheet在iOS8中已弃用。使用适用于iOS 8或更高版本的UIAlertController
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];
尝试使用此操作表模拟：
@interface UIViewController (ActionSheetSimulation)
-(UIView*) actionSheetSimulationWithPickerView:(UIPickerView*)pickerView withToolbar: (UIToolbar*)pickerToolbar;
-(void)dismissActionSheetSimulation:(UIView*)actionSheetSimulation;

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 -

我遇到了同样的问题并通过这种方式解决了它将适用于所有ios版本
在ios 8中，苹果已经改变了很多东西我在这里遇到了我自己的项目中的一个问题所以，我只是想提供替代UIActionsheet的解决方案。
在ios 8中，UIActionsheet也被弃用了，其委托方法也被弃用了。而不是与prefferedstyle的UIAlertController
使用UIAlertControllerStyleActionSheet。你也可以查看这个帖子：

此示例适用于ios 8及其早期版本。
在.h文件中声明此变量

谢谢。
看看我的代码
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil
message:@"\n\n\n\n\n\n\n\n\n\n\n" preferredStyle:UIAlertControllerStyleActionSheet];
__weak typeof(self) weakSelf = self;
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"确认"style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
[weakSelf pickActionSheetFinishAction];
[alertController addAction:cancelAction];
[alertController.view addSubview:self.topicPickView];
[self presentViewController:alertController animated:YES completion:nil];
我有同样的问题，显示带有UIActionSheet的UIPickerView在iOS 8中不起作用。因为UIActionSheet已弃用，Apple建议使用UIAlertController。所以我们应该绕风。
我写了一些代码来解决我的问题。我希望它可以帮到你。
#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)];
}];
}
}
我认为这都是解决这个问题的方法。快乐的编码！

你可以使用UIAlertController来做到这一点。
@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)
}
像这样设置pickerView的委托和数据源
class MyViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource
设置委托和数据源函数
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
}
