ios - 带有 UIToolbar 的 UIDatePicker

Question

我正在尝试在 UIDatepicker 上实现 UIToolbar 以在触摸“完成”按钮时将其关闭。但是当我点击按钮时，日期选择器正在滚动并且操作按钮不起作用。

这是我的代码:

datepicker = [[UIDatePicker alloc] initWithFrame:CGRectZero];
[datepicker setDatePickerMode:UIDatePickerModeDate];
[datepicker addTarget:self action:@selector(changeDate:) forControlEvents:UIControlEventValueChanged];

UIToolbar *toolbar= [[UIToolbar alloc] initWithFrame:CGRectMake(0,0,self.view.frame.size.width,44)];
toolbar.barStyle = UIBarStyleDefault;
UIBarButtonItem *flexibleSpaceLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(dismiss)];

[toolbar setItems:[NSArray arrayWithObjects:flexibleSpaceLeft, doneButton, nil]];
[datepicker addSubview:toolbar];

我的日期选择器:

感谢您的帮助。

如果使用 UITextField 设置

textField.inputAccessoryView = toolbar;
textField.inputView = datepicker;
