问题描述

我需要在这个图像中添加一个完成按钮给我的日期选择器：

I need to add a "done" button to my date picker like in this image:

这是我的代码：

-(IBAction)chooseDate:(id)sender{
self.datepicker= [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 0, 320, 216)];
    self.datepicker.datePickerMode = UIDatePickerModeDate;
    datepicker.backgroundColor = Rgb2UIColor(52, 170, 220);

    [self.btnDone
                addTarget:self
                action:@selector(SetDatePickerTime:)
                forControlEvents:UIControlEventTouchDown];

 [self.view addSubview:self.datepicker];
}

推荐答案

创建日期选择器将其添加为有问题的字段的输入视图（ self.fieldInQuestion.inputView = datePicker ）。接下来，创建一个 UIToolBar （高度44）与 UIBarButton 项目上标题为完成，自我的目标，和一个选择器（例如@selector（完成））。将其添加为相同字段的输入附件视图，您将日期选择器设置为（ self.fieldInQuestion.inputAccessoryView = UIToolbarInstance ）的输入视图。在上面的示例中的选择器方法（ - （void））中，确保使用[self.fieldInQuestion resignFirstResponder]，它将会关闭它。

Create a date picker, then add it as the input view of the field in question (self.fieldInQuestion.inputView = datePicker). Next, create a UIToolBar (height 44) with UIBarButton Item on it with the title "Done", target of self, and a selector (ex. @selector(done)). Add this as the input accessory view of the same field you made the date picker an input view for (self.fieldInQuestion.inputAccessoryView = UIToolbarInstance). In the selector method (-(void)done in the example above), make sure you use [self.fieldInQuestion resignFirstResponder] and it will dismiss it.
