标题: ios - UIDatePicker 未在 UITable 上正确显示

我有一个 UITableCell 并且在该单元格上我有一个 UITextBox，当单击文本框而不是显示键盘时，将显示一个 UIDatePicker 并使用下面的代码。但我无法定位 UIDatePicker。我需要它从页面的最底部开始，此时它似乎从按下文本框的表格部分的顶部开始。当用户单击首选日期标签时，代码会触发。任何指针？我附上了一张图片来显示它当前的渲染位置。谢谢。

- (IBAction)selectDateBeginid)sender {


    //Disable Keyboard
    [self.txtBookingDate resignFirstResponder];
    //Disable Scrolling
    [_tableForm setScrollEnabled:false];

    if ([self.view viewWithTag:9]) {
        return;
    }
    CGRect toolbarTargetFrame = CGRectMake(0, self.view.bounds.size.height-216-44, 320, 44);
    CGRect datePickerTargetFrame = CGRectMake(0, self.view.bounds.size.height-216, 320, 216);

    UIView *darkView = [[UIView alloc] initWithFrame:self.view.bounds];
    darkView.alpha = 0;
    darkView.backgroundColor = [UIColor blackColor];
    darkView.tag = 9;
    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self actionselector(dismissDatePicker] ;
    [darkView addGestureRecognizer:tapGesture];
    [self.view addSubview:darkView];

    UIDatePicker *datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height+44, 320, 216)] ;
    datePicker.tag = 10;
    [datePicker addTarget:self actionselector(changeDate forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:datePicker];

    UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height, 320, 44)];
    toolBar.tag = 11;
    toolBar.barStyle = UIBarStyleBlackTranslucent;
    UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self actionselector(dismissDatePicker];
    [toolBar setItems:[NSArray arrayWithObjects:spacer, doneButton, nil]];
    [self.view addSubview:toolBar];

    [UIView beginAnimations"MoveIn" context:nil];
    toolBar.frame = toolbarTargetFrame;
    datePicker.frame = datePickerTargetFrame;
    darkView.alpha = 0.5;
    [UIView commitAnimations];
}

Best Answer-推荐答案

我建议你用这个指令替换你的 textField 的 inputView(默认是键盘):

UIDatePicker *datePicker = [[UIDatePicker alloc] init] ;
[datePicker addTarget:self actionselector(changeDate forControlEvents:UIControlEventValueChanged];

[preferredDateField setInputView:datePicker];

更合适且符合 Apple 人机界面指南
