ios 6：UITextField中的UIDatePicker

Question

I have problems with connecting datepicker with text field. I have tried all solution from stackoverflow but they don't work in ios 6. Can you desribe how to make it, I want to tap on text field and choose date via datepicker.

Answer 1

You should use the inputView property of your UITextField to make the picker show in place of the keyboard. iOS6 will take care of everything for you then (showing the picker with the animation instead of the keyboard, etc).

Note: You will probably want to add some inputAccessoryView too (generally an UIToolBar with some "OK" button in it) to make the user be able to dismiss the picker (the IBAction of your "OK" button will simply call [textField resignFirstResponder] for that to happen of course) as an UIDatePicker does not have any button to validate your input (whereas the keyboard has its "Return Key")

#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];  
}
