//给UIDatePicker设置date
-(void)textFieldDidBeginEditing:(UITextField *)textField{
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    formatter.dateFormat = @"HH:mm";
    NSDate *date = [formatter dateFromString:self.text];
    [self.picker setDate:date];
}

为什么"00:00"这个字符串会被转换为上午12:00 ?
