iphone - 将 UIButton 的文本设置为日期

Question

我有一个 UIButton，单击它会弹出一个 UIDatePicker 来设置它的日期。

一切都已设置好，包括动画的进出等。

我需要什么帮助:

默认情况下，将按钮的文本标签设置为当天的日期。然后在 UIDatePicker 关闭后将其设置为新选择的日期。

 - (IBAction)dateButtonPressed
{
    [dateView setFrame:CGRectMake(0, self.view.frame.size.height, self.view.frame.size.width, self.view.frame.size.height)];
    [self.view addSubview:dateView];

    [UIView animateWithDuration:.5 animations:^{
        [dateView setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
    }];
}

- (IBAction)dismssPicker
{
    [dateView setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];

    [UIView animateWithDuration:.5 animations:^{
        [dateView setFrame:CGRectMake(0, self.view.frame.size.height, self.view.frame.size.width, self.view.frame.size.height)];
    } completion:^(BOOL finished){ [dateView removeFromSuperview]; }];
}
