UIPickerView与完成按钮

我有一个UIPickerView在我的应用程序，我想有一个完成按钮来隐藏选择器。UIPickerView与完成按钮

我不想使用操作表，因为我想专注于view.i的其余部分，我的意思是所有的视图必须是活动的。

这里是我创建的选择器：

UIPickerView *pickerViewCountry = [[UIPickerView alloc] init]; 
    pickerViewCountry.showsSelectionIndicator = YES; 
    pickerViewCountry.dataSource = self; 
    pickerViewCountry.delegate = self; 
    pickerViewCountry.frame = CGRectMake(0,210 , 320, 15); 
    [self.view addSubview:pickerViewCountry]; 
    [pickerViewCountry release];

您可以通过添加与UIPickerView的动画完成按钮UIToolBar做到这一点。

尝试自定义选择器使用行动表

UIActionSheet *actionSheet; 
NSString *pickerType; 
-(IBAction)BtnPressed:(id)sender 
{ 
    [self createActionSheet]; 
    pickerType = @"picker"; 
    select = NO; 
    UIPickerView *chPicker = [[UIPickerView alloc] initWithFrame:CGRectMake(0.0, 44.0, 0.0, 0.0)]; 
    chPicker.dataSource = self; 
    chPicker.delegate = self; 
    chPicker.showsSelectionIndicator = YES; 
    [actionSheet addSubview:chPicker]; 
    sessoTxt.text = [sessoArray objectAtIndex:0]; 
    [chPicker release]; 
} 
- (void)createActionSheet { 
    if (actionSheet == nil) { 
     // setup actionsheet to contain the UIPicker 
     actionSheet = [[UIActionSheet alloc] initWithTitle:@"Select" 
                delegate:self 
             cancelButtonTitle:nil 
            destructiveButtonTitle:nil 
             otherButtonTitles:nil]; 

     UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)]; 
     pickerToolbar.barStyle = UIBarStyleBlackOpaque; 
     [pickerToolbar sizeToFit]; 

     NSMutableArray *barItems = [[NSMutableArray alloc] init]; 

     UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil]; 
     [barItems addObject:flexSpace]; 
     [flexSpace release]; 

     UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(pickerDone:)]; 
     [barItems addObject:doneBtn]; 
     [doneBtn release]; 

     [pickerToolbar setItems:barItems animated:YES]; 
     [barItems release]; 

     [actionSheet addSubview:pickerToolbar]; 
     [pickerToolbar release]; 

     [actionSheet showInView:self.view]; 
     [actionSheet setBounds:CGRectMake(0,0,320, 464)]; 
    } 
}

行动_sheet_，肯定？ :) – jrturton 2011-12-23 07:06:21

是的，我已经在我的许多应用程序实施 – Hiren 2011-12-23 07:08:48

在这里相同。这种方法也适用于我的应用程序。 – Raptor 2013-08-07 10:23:11

选择器视图应该在哪里你进入该国被设置为文本字段的inputView。您应该创建一个带有标准完成系统项目的工具栏，并将其设置为同一字段的inputAccessoryView。

我甚至会尝试使用类似EAActionSheetPicker的东西。它管理一个actionSheet内部的pickerView/datePicker的显示。它可能就是你要找的东西。

尽量避免只有链接的答案。也许一小段代码将帮助OP。 – Raptor 2013-08-07 10:22:44

您可以将工具栏添加到UIPickerView这样的：

// initiaize picker view 
UIPickerView *pickerView=[[UIDatePicker alloc]init];//Date picker 
pickerView.frame=CGRectMake(0,44,320, 216); 
pickerView.datePickerMode = UIDatePickerModeDate; 
[pickerView setMinuteInterval:5]; 
[self.view addsubview:pickerView] 

toolBar= [[UIToolbar alloc] initWithFrame:CGRectMake(0,0,320,44)]; 
[toolBar setBarStyle:UIBarStyleBlackOpaque]; 
UIBarButtonItem *barButtonDone = [[UIBarButtonItem alloc] initWithTitle:@"Done" 
    style:UIBarButtonItemStyleBordered target:self action:@selector(changeDateFromLabel:)]; 
toolBar.items = [[NSArray alloc] initWithObjects:barButtonDone,nil]; 
barButtonDone.tintColor=[UIColor blackColor]; 
[pickerView addSubview:toolBar];

Latika Tiwari您可以给changeDateFromLabel方法编码以隐藏日期选取器视图吗？ – user3182143 2014-02-28 13:03:15
