ios 6：UITextField 中的 UIDatePicker

Question

我在将日期选择器与文本字段连接时遇到问题。我已经尝试了 stackoverflow 中的所有解决方案，但它们在 ios 6 中不起作用。你能描述一下如何制作吗，我想点击文本字段并通过 datepicker 选择日期。

Answer 1

您应该使用UITextField 的inputView 属性来使选择器代替键盘显示。然后，iOS6 将为您处理所有事情（使用动画而不是键盘等显示选取器）。

注意：您可能还想添加一些inputAccessoryView（通常是带有一些“确定”按钮的UIToolBar）以使用户能够关闭选择器（IBAction您的“确定”按钮将简单地调用[textField resignFirstResponder] 以实现这一点）因为UIDatePicker 没有任何按钮来验证您的输入（而键盘有其“返回键”）

#import "TextfieldwithDatepickerViewController.h"

UIActionSheet *pickerViewPopup;

@implementation TextfieldwithDatepickerViewController
- (void)textFieldDidBeginEditing:(UITextField *)aTextField{  
    [aTextField resignFirstResponder];  

    pickerViewPopup = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];  

    UIDatePicker *pickerView = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 44, 0, 0)];  
    pickerView.datePickerMode = UIDatePickerModeDate;  
    pickerView.hidden = NO;  
    pickerView.date = [NSDate date];  

    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];  

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

    UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancelButtonPressed:)];  
    [barItems addObject:cancelBtn];  

    [pickerToolbar setItems:barItems animated:YES];  

    [pickerViewPopup addSubview:pickerToolbar];  
    [pickerViewPopup addSubview:pickerView];  
    [pickerViewPopup showInView:self.view];  
    [pickerViewPopup setBounds:CGRectMake(0,0,320, 464)];  
}  

-(void)doneButtonPressed:(id)sender{  
    //Do something here here with the value selected using [pickerView date] to get that value  

    [pickerViewPopup dismissWithClickedButtonIndex:1 animated:YES];  
}  

-(void)cancelButtonPressed:(id)sender{  
    [pickerViewPopup dismissWithClickedButtonIndex:1 animated:YES];  
}
