如何在UIActionSheet中添加UIPickerView

Question

我有任務輸入等級（1 - 5）的值，所以我發現下面的代碼爲日期選擇器，任何人都可以幫助我改變下面的代碼，以便添加UIPickerView以選擇速率1至5

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]; 

什麼爲收視率做這樣的文本框將自動與選定的價值

Answer 1

首先，我想你可能會混淆一個UIPickerView具有UIDatePickerView 。日期選取器是一個專門的選取器，當UIPickerView專門用於定製時，不能定製。 Marc W在他的評論中是正確的。 I answered this question before，並且感覺它提供了比試圖將選取器添加到UIActionSheet更好的解決方案。

那裏有很多UIPickerView教程。

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]; 

Answer 3

該解決方案適用於橫向和4英寸的屏幕。

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;
