看看this blog post。它提供category，有助于将日期和字符串转换为反之亦然。您需要根据NSDate解析format对象，然后分配给某些UITextField或UILabel

修改

您已成功解析了日期，但未将message变量分配给UITextField，您的代码应如下所示：

case 0:
{

    NSDate  *selected=[_datePicker date];
    NSString *message=[[NSString alloc]initWithFormat:@"date and time like:%@",selected];

    // Assign to the control here
    yourTextField.text = message;
}
