Answer 1

• First indicate that your class conforms to the UITextFieldDelegate protocol

• Then in viewDidLoad set the delegate and tag of your text field.

   yourTextField.delegate = self;  
   yourTextField.tag = 111;
  

• Then implement the following delegate method:

  - (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {   
      if (textField.tag==111) {  
          [self showDatePicker];  
      }  
      return YES;  
  }
  

• Now implement a function showDatePicker

  - (void)showDatePicker {  
      datePicker = [[UIDatePicker alloc] init];
      datePicker.backgroundColor=[UIColor whiteColor];
  
      UIToolbar *toolbar = [[UIToolbar alloc]init];
      [toolbar sizeToFit];
  
      UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(showSelectedDate)];    
  
      doneBtn.tintColor = [UIColor whiteColor];  
  
      UIBarButtonItem *flexibleSpaceLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];    
  
      toolbar.backgroundColor = [UIColor colorWithRed:5.0/255.0 green:110.0/255.0 blue:170.0/255.0 alpha:1];  
  
      [toolbar setItems:[NSArray arrayWithObjects:flexibleSpaceLeft,doneBtn ,nil]];  
  
      [yourTextField setInputAccessoryView:toolBar];  
  
      yourTextField.inputView = datePicker;   
  }
  

OR you can do it simply in your viewDidLoad as follows:

datePicker = [[UIDatePicker alloc] init];
datePicker.backgroundColor = [UIColor whiteColor];  

UIToolbar *toolbar = [[UIToolbar alloc]init]; 

[toolbar sizeToFit];    

 UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self
 action:@selector(showSelectedDate)];    

 doneBtn.tintColor = [UIColor whiteColor];  

 UIBarButtonItem *flexibleSpaceLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
 target:nil action:nil];    

toolbar.backgroundColor = [UIColor colorWithRed:5.0/255.0 green:110.0/255.0 blue:170.0/255.0 alpha:1];  

[toolBar setItems:[NSArray arrayWithObjects:flexibleSpaceLeft, doneBtn , nil]];  

[yourTextField setInputAccessoryView:toolbar];  

yourTextField.inputView = datePicker;
