在iOS8中显示UIPickerViewwith不起作用UIActionSheet
该代码在iOS7中有效，但在iOS8中无效。我确定这是因为 UIActionSheet 在iOS8中已被弃用，Apple 建议使用UIAlertController.
但是，如何在iOS8中做到这一点？我应该使用UIAlertController？

从 UIActionSheet 的参考：
UIActionSheet 不是为子类而设计的，也不应该将视图添加到它的层次结构中。如果您需要呈现比 UIActionSheet API 提供的自定义更多的表单，您可以创建自己的表单并使用 presentViewController:animated:completion: 以模态方式呈现它。
我的猜测是你明白为什么。
UIAlertController 的参考没有类似的免责声明，但是看它的界面，我猜苹果会在发布前添加它。
我的建议是创建一个包含您的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，并且您不会将接口推向超出其预期用途的范围。

我自己编写时间选择器，而不是 iOS8 中的 UIActionSheet：
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:

UIActionSheet 在iOS8中被弃用。使用iOS8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];

我遇到了同样的问题并通过这种方式解决了它适用于所有 ios 版本
在 ios 8 中，苹果改变了很多东西，我在自己的项目中遇到了一个问题，所以我只想提供解决方案来替代UIActionsheet.
在 ios 8UIActionsheet中，它的委托方法也被弃用了。而不是UIAlertController使用 prefferedstyle
UIAlertControllerStyleActionSheet 。你也可以检查这个线程：
https://developer.apple.com/library/ios/documentation/Uikit/reference/UIActionSheet_Class/index.html
此示例适用于 ios 8 和之前的版本。
在 .h 文件中声明此变量
@interface demoProfileForBuyer{
UIActionSheet *ac_sheet_fordate;
UIToolbar *pickerToolBar_fordate;
UIDatePicker *optionPickerDate;
UIAlertController *alertController;
}
在 .m 文件中
- (void)viewDidLoad
{
[super viewDidLoad];
pickerToolBar_fordate = [[UIToolbar alloc] initWithFrame:CGRectMake(-8, 0, 320, 44)];

尝试使用此操作表模拟：
@interface UIViewController (ActionSheetSimulation)
-(UIView*) actionSheetSimulationWithPickerView:(UIPickerView*)pickerView withToolbar: (UIToolbar*)pickerToolbar;
-(void)dismissActionSheetSimulation:(UIView*)actionSheetSimulation;
@end
#import "UIViewController+ActionSheetSimulation.h"

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 -
pickerView.frame.size.height +
UIApplication.sharedApplication.statusBarFrame.size.height;
[pickerView setFrame:CGRectMake(pickerView.frame.origin.x,
pickerViewYpositionHidden,
pickerView.frame.size.width,
pickerView.frame.size.height)];
[pickerToolbar setFrame:CGRectMake(pickerToolbar.frame.origin.x,
pickerViewYpositionHidden,
pickerToolbar.frame.size.width,

pickerView.backgroundColor = [UIColor whiteColor];
[simulatedActionSheetView addSubview:pickerToolbar];
[simulatedActionSheetView addSubview:pickerView];
[UIApplication.sharedApplication.keyWindow?UIApplication.sharedApplication.keyWindow:UIApplication.sharedApplication.windows[0]

return simulatedActionSheetView;

您可以使用 anUIAlertController来执行此操作。
@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的代表和数据源
class MyViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource
设置委托和数据源功能
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
}

我和你有同样的问题，用 UIActionSheet 显示 UIPickerView 在 iOS 8 中不起作用。因为 UIActionSheet 已被弃用，Apple 建议使用 UIAlertController。所以我们应该绕着风。
我写了一些代码来解决我的问题。我希望它可以帮助你。
#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)];
}];
}
}
我认为这一切都是为了解决这个问题。快乐编码！
