我無法設置視圖控制器&表視圖的幀大小。這是我的看法層次結構無法在iphone中使用xcode 4設置表格視圖和視圖控制器的幀大小
內容畫面添加爲滾動視圖子視圖的圖像。我的內容視圖包含標籤，以編程方式添加的按鈕&文本視圖。
但是根據我下面列出的代碼，我無法設置視圖控制器框架的表視圖框架&。我的表格視圖是框架設置不正確&這就是爲什麼我必須向上/向下滾動以查看我的表格單元格內容。所以我有2個滾動條，即1表示滾動視圖& 1。
這裏是我的代碼

所以我需要計算相應的設置表視圖&內容視圖的框架表視圖&的框架。我怎樣才能做到這一點？
這是怎麼應用的樣子現在
歐文，你說得對。我添加內容視圖使用[self.scrollView addSubview：self.contentView]將視圖作爲子視圖滾動;我使用內容視圖來顯示標籤，按鈕和文本視圖，而不是直接放在滾動視圖上。 – iOSAppDev
但它不能解決問題。我只是添加內容視圖作爲子視圖滾動視圖使用編程 – iOSAppDev
您可以使用CGRect臨時變量來設置您的框架：CGRect myFrame = tableview.frame; myFrame.origin.y = 100; myFrame.origin.x = 100; [tableview setFrame：myFrame]; –
