我試圖在iPad上製作一個簡單的應用程序。目前,我只能在自定義視圖中顯示全屏圖片。我的問題是,當iPad旋轉時,我的視圖不會自動調整...旋轉完美,但是圖像的大小仍然相同。我的子視圖在旋轉後未自動調整
我的應用程序基於this,因爲我在切換圖片時需要此效果。基本上,產生效果的視圖是FlipView
,其繼承形式GenericAnimationView
,其形式爲UIView
。還有AnimationFrame
從NSObject
繼承,需要顯示1個動畫循環。最後,有AnimationDelegate
繼承自NSObject
,它處理來自變換操作的回調。
這裏是我的AnimationViewController

我,他們談到了自動調整大小面具,但我不能讓其他職位看到...
任何想法或建議?謝謝!
我不明白...我在哪裏做的?我沒有'.storyboard' – castors33 2012-07-17 13:32:19
點擊你想在你的xib文件中修改的圖像視圖。然後按下Command-Option-5。這將帶來尺寸檢查員。在顯示「Autosizing」的框中,您可以切換紅色箭頭和連接器以更改旋轉設備時視圖的大小調整方式。還要確保屬性檢查器(Command-Option-4)中的「模式」設置爲「Scale to Fill」(圖像縮放),以便您的圖像 – 2012-07-17 15:33:56
我沒有尺寸檢查器這樣的東西...我想它需要有一個'.storyboard' – castors33 2012-07-17 15:51:55
