在 iOS8 中显示UIPickerView
UIActionSheet
无效
代码适用于 iOS7 ,但它无法在 iOS8 中使用。我确定这是因为UIActionSheet在 iOS8 中已弃用,Apple建议使用UIAlertController
。
但是,如何在 iOS8 中执行此操作?我应该使用UIAlertController
?

来自UIActionSheet的参考资料:
UIActionSheet不是为子类设计的,也不应该在其层次结构中添加视图。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的参考资料没有类似的免责声明,但是看看它的界面,我的猜测是Apple会在发布之前添加它。
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,而且你没有超越其预期用途推动界面。

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:
[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],

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]];

UIActionSheet在 iOS8 中已弃用。将 UIAlertController 用于 iOS8或更高版本
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];

我遇到了同样的问题并通过这种方式解决了它,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,我在这里面对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。
UIActionsheet

我遇到了同样的问题,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)];
}];
}
}
我认为解决这个问题的全部内容。 快乐的编码!

您可以使用UIAlertController
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的委托和数据源
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
}
