uitviewcontroller與uitableview和自定義uitablextfields uitablextfields與uitextfields向上/向下滾動鍵盤

我有一些困難找出最佳方式來讓我的uitextfields不會隱藏當鍵盤彈出。現在我有一個包含uitableview子視圖和按鈕的UIView。uitviewcontroller與uitableview和自定義uitablextfields uitablextfields與uitextfields向上/向下滾動鍵盤

* uview中的tableview實際上是一個uiviewcontroller，它帶有一個編程創建的tableivew，所以它不受uitableviewcontroller控制。

我已經完成了研究，我認爲我需要一個滾動視圖，然後將視圖添加到滾動視圖，並在選擇特定文本框並使用鍵盤向上滾動時隱藏某些滾動。

這是一個很好的方法嗎？

UPDATE：

我有兩個單獨的Viewcontrollers。例如讓我們說MainViewcontroller和SecondViewcontroller。第二個viewcontroller有一個可用的視圖。表格視圖內的單元格具有存儲用戶信息的文本框（如表單）。然後我在mainviewcontroller裏面創建了secondviewcontroller的一個對象。我這樣做了，因爲我需要在視圖底部有一個「下一個按鈕」。當我選擇一個字段時，它將位於鍵盤下方，當它彈出時，我想讓它向上滾動，當它關閉時它會下降。我不得不使用uitableview的一個對象，因爲Mainviewcontroller類會變得很大（如果我錯了，請糾正我）。謝謝回覆。

這裏就是我試圖做... 充分的UIView的截圖：開放http://postimage.org/image/puzdwpj3t/ 隨着鍵盤：http://postimage.org/image/g5nkwzwpd/

//下面是一些代碼： 1.這裏的第一類是如SecondViewcontroller。 2.代碼的第二部分是例如mainviewcontroller，它創建secondviewcontroller的一個對象。

下面的uiviewcontroller將創建一個包含3個部分的表格。每個單元格都有一個文本框（除了中間部分，它是一個拉起uipickerview的按鈕）。這不是一個完整的課程，我只是在創建表格的地方。

您已經添加泰伯維內部視圖的UIViewController。對？

在哪個視圖中添加了UITextview。？ UIViewController視圖？

您可以在UIView中添加UITextView，並通過應用動畫改變UITextView的框架。

Ex。

//以查看UP ....

[UIView animationWithDuration:secs delay:0.0 option:option animation:^{ 

    CGRect frame = textview.frame; 
    frame.origin.y = 10; // Change Y position of frame. 
    textview.frame = frame; 

} 
completion:nil];

//就拿下來查看

[UIView animationWithDuration:secs delay:0.0 option:option animation:^{ 

    CGRect frame = textview.frame; 
    frame.origin.y = 100; // Change Y position of frame. 
    textview.frame = frame; 

} 
completion:nil];

沒有必要採取UIScrollView的。
