如何在UIActionSheet中添加UIPickerView

[英]how to add UIPickerView in UIActionSheet

 原文  2009-12-24 16:27:59  3   4    iphone/ uipickerview/ uiactionsheet

問題描述

我有任務輸入評級（1 - 5）值，所以我發現以下代碼為日期選擇器，任何人都可以幫我改變下面的代碼，以便添加UIPickerView選擇從1到5的比率 

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];

該做什么，所以評級的文本字段將自動輸入UIPIckerView中的選定值

謝謝

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];

首先，我認為您可能會將UIPickerView與UIDatePickerView混淆。 日期選擇器是一個專門的選擇器，當UIPickerView專門用於自定義時，無法自定義。 Marc W的評論是正確的。 之前我回答過這個問題並且認為它提供了比嘗試將選擇器添加到UIActionSheet更好的解決方案。

有很多UIPickerView教程。

此解決方案適用於橫向和4英寸屏幕。 

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;
