問(wèn)題描述
我是 Objective-C 編程的新手.
我正在使用帶有一些標(biāo)簽、圖像和文本視圖的 UIScrollView.
我已經(jīng)關(guān)閉了自動(dòng)布局，并且已經(jīng)嘗試開啟(標(biāo)題中描述的情況)和關(guān)閉(不滾動(dòng))調(diào)整滾動(dòng)視圖插圖".
這是我在 viewDidLoad 中插入的內(nèi)容:
[scroller setScrollEnabled:YES];[滾輪 setContentSize:CGSizeMake(320, 687)];但我一定遺漏了一些非常簡(jiǎn)單的東西.
1...為什么UIScrollView在頂部留下空間
使用 Storyboard- 轉(zhuǎn)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(shè)置viewController屬性automaticallyAdjustsScrollViewInsets為NO，默認(rèn)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(dòng)到底部
要使其滾動(dòng)，請(qǐng)嘗試在 contentSize 中使用較大的數(shù)字，例如 CGSizeMake(320, 1687).如果它有效，則意味著您沒有將 contentSize 設(shè)置得足夠大以容納其所有內(nèi)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.
這篇關(guān)于為什么UIScrollView在頂部留下空間并且不滾動(dòng)到底部的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
