即使我爲keypath添加contentSize，UIScrollview也不滾動？

嘿，我有一個嵌入在視圖中的UI滾動視圖。然而;即使我在IB Keypath中設置contentSize，它仍然不會滾動？即使我爲keypath添加contentSize，UIScrollview也不滾動？

有什麼建議嗎？

請發佈你的相關代碼。 – trumpetlicks

它沒有與故事板編輯器一起構建的代碼。在關鍵路徑內。 – Tukajo

我有一個DigitalVC.m類是花花公子，控制它很好，並控制UI，但我可以發佈故事板的屏幕截圖 – Tukajo

選擇所有的自動調整大小視覺選項的工作和固定的我問題。我不知道爲什麼（盒子裏的紅線爲你縮放視圖）

取消選中useAutoLayout兩者的UIView和UIScrollView的來自IB的autoResizeSubviews然後嘗試

試過，沒有去喬。 – Tukajo

真的，只有autoResizeSubviews應該與UIScrollView有關，而不是UIView。 – trumpetlicks

在滾動上放置了一些bg顏色，然後嘗試找到你可以在視圖中看到它還是不是？ – umairhhhs

即使我爲keypath添加contentSize，UIScrollview也不滾動？
