問題描述
我是 Objective-C 編程的新手.
我正在使用帶有一些標簽、圖像和文本視圖的 UIScrollView.
我已經關閉了自動布局，并且已經嘗試開啟(標題中描述的情況)和關閉(不滾動)調整滾動視圖插圖".
這是我在 viewDidLoad 中插入的內容:
[scroller setScrollEnabled:YES];[滾輪 setContentSize:CGSizeMake(320, 687)];但我一定遺漏了一些非常簡單的東西.
1...為什么UIScrollView在頂部留下空間
使用 Storyboard- 轉到視圖控制器 > 屬性檢查器 > 取消選中 Adjust Scroll View Insets 屬性
With Code- 額外空間設置viewController屬性automaticallyAdjustsScrollViewInsets為NO，默認為是.
self.automaticallyAdjustsScrollViewInsets = false;scroller.contentInset = UIEdgeInsetsZero;scroller.scrollIndicatorInsets = UIEdgeInsetsZero;scroller.contentOffset = CGPointMake(0.0, 0.0);<塊引用>
2...不滾動到底部
要使其滾動，請嘗試在 contentSize 中使用較大的數字，例如 CGSizeMake(320, 1687).如果它有效，則意味著您沒有將 contentSize 設置得足夠大以容納其所有內容.
I am new to objective-C programming.
I am using UIScrollView with some labels, image and text view on it.
I have turned off Autolayout and already tried with "Adjust scroll View Insets" on (situation described in title) and off (doesn't scroll).
This is what I insert into viewDidLoad:
[scroller setScrollEnabled:YES];
[scroller setContentSize:CGSizeMake(320, 687)];
But I must be missing something very simple.
1... Why is UIScrollView leaving space on top
With Storyboard- Goto view controller > Attribute Inspector > Uncheck Adjust Scroll View Insets property
With Code- For extra space set viewController property automaticallyAdjustsScrollViewInsets to NO, by default it is YES.
self.automaticallyAdjustsScrollViewInsets = false;
scroller.contentInset = UIEdgeInsetsZero;
scroller.scrollIndicatorInsets = UIEdgeInsetsZero;
scroller.contentOffset = CGPointMake(0.0, 0.0);
2... does not scroll to the bottom
To make it scroll try with large number in contentSize like CGSizeMake(320, 1687). If it works that means you are not setting the contentSize large enough to have all its content.
