【中文标题】如何在 UIActionSheet 中添加 UIPickerView【英文标题】：how to add UIPickerView in UIActionSheet 【发布时间】：2009-12-24 16:27:59 【问题描述】：我有输入 rating(1 - 5) 值的任务，所以我找到了以下日期选择器代码，谁能帮我修改下面的代码，以便添加 UIPickerView 以从 1 到 5 选择速率
UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Ratings"
delegate:self
cancelButtonTitle:@"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:nil];
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeDate;
[menu addSubview:pickerView];
[menu showInView:self.view];
[menu sendSubviewToBack:pickerView];
[menu setBounds:CGRectMake(0,0,320, 500)];
CGRect pickerRect = pickerView.bounds;
pickerRect.origin.y = -100;
pickerView.bounds = pickerRect;
[pickerView release];
[menu release];
如何做，评分的文本字段将自动输入 UIPIckerView 中的选定值
谢谢
【问题讨论】：
已经有人问过这个问题了。见这里：***.com/questions/1849873/… 【参考方案1】：actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0,40, 320, 216)];
picker.showsSelectionIndicator=YES;
picker.dataSource = self;
picker.delegate = self;
picker.tag=SelectedDropDown;
[actionSheet addSubview:picker];
UIToolbar *tools=[[UIToolbar alloc]initWithFrame:CGRectMake(0, 0,320,40)];
tools.barStyle=UIBarStyleBlackOpaque;
[actionSheet addSubview:tools];
[tools release];
UIBarButtonItem *doneButton=[[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleBordered target:self action:@selector(btnActinDoneClicked)];
doneButton.imageInsets=UIEdgeInsetsMake(200, 6, 50, 25);
UIBarButtonItem *flexSpace= [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
NSArray *array = [[NSArray alloc]initWithObjects:flexSpace,doneButton,nil];
[tools setItems:array];
[doneButton release];
[flexSpace release];
//picker title
UILabel *lblPickerTitle=[[UILabel alloc]initWithFrame:CGRectMake(60,8, 200, 25)];
lblPickerTitle.text=@"";
lblPickerTitle.backgroundColor=[UIColor clearColor];
lblPickerTitle.textColor=[UIColor whiteColor];
lblPickerTitle.textAlignment=NSTextAlignmentCenter;
lblPickerTitle.font=[UIFont boldSystemFontOfSize:15];
[tools addSubview:lblPickerTitle];
[actionSheet showFromRect:CGRectMake(0,480, 320,215) inView:self.view animated:YES];
[actionSheet setBounds:CGRectMake(0,0, 320, 411)];
[actionSheet release];

【参考方案2】：首先，我认为您可能会将 UIPickerView 与 UIDatePickerView 混淆。日期选择器是一个无法自定义的专用选择器，而 UIPickerView 是专门用于自定义的。 Marc W 在他的评论中是正确的。我answered this question before 认为它提供了比尝试将选择器添加到 UIActionSheet 更好的解决方案。
那里有很多 UIPickerView 教程。

UIActionSheet *aac = [[UIActionSheet alloc] initWithTitle:@"Choose Date and Time"
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[datePicker addTarget:self action:@selector(dateChanged) forControlEvents:UIControlEventValueChanged];
pickerDateToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
pickerDateToolbar.barStyle = UIBarStyleBlackOpaque;
[pickerDateToolbar sizeToFit];
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
[barItems addObject:flexSpace];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(DatePickerDoneClick)];
[barItems addObject:doneBtn];
[pickerDateToolbar setItems:barItems animated:YES];
[aac addSubview:pickerDateToolbar];
[aac addSubview:datePicker];
[aac showFromTabBar:self.tabBarController.tabBar];
CGFloat wideth = self.view.frame.size.width;
if (UIDeviceOrientationIsLandscape([self interfaceOrientation]))
[aac setBounds:CGRectMake(0,0,wideth, 355)];
[datePicker sizeToFit];
else
[aac setBounds:CGRectMake(0,0, wideth, 470)];
[datePicker sizeToFit];
picker = aac;
