我有一個MainMenu.xib文件,我有一個名爲「首選項」的窗口 另外我有四個不同高度的自定義視圖。和該窗口上的工具欄。 我已經將每個工具欄項鍊接到 - (void)switchViews:(id)sender;功能。視圖被鏈接並顯示並且也在變化,但問題是,如果我從一個視圖切換到另一個視圖,然後再切換回另一個視圖,視圖上的內容(即按鈕,標籤,複選框不斷向上移動,窗口仍然不斷改變到正確的高度,但如果我切換足夠的時間內容將從視圖中消失..任何形式的幫助將是有用的。使用工具欄在自定義視圖之間切換

與你所描述的,在你的代碼一眼我就開始懷疑這條線的問題...

frame.origin.y -= (newSize.height - oldSize.height);
