問(wèn)題描述
我在 nib 的 view 中放置了一個(gè) UIScrollView，并將其鏈接到一個(gè) IBOutlet 屬性.
I put a UIScrollView in my nib's view, and linked it to a an IBOutlet property.
現(xiàn)在，當(dāng)我在 viewDidLoad 方法中執(zhí)行此操作時(shí)，它似乎對(duì) contentSize 沒(méi)有影響:
Now, when I do this in my viewDidLoad method, it seems to have no effect on the contentSize:
self.sv.backgroundColor = [UIColor yellowColor]; // this works
CGSize size = CGSizeMake(1000.0, 1000.0);
[self.sv setContentSize:size]; // this does not
它的行為就好像 contentSize 與框架相同.這是怎么回事?當(dāng)我關(guān)閉自動(dòng)布局時(shí)，這開(kāi)始工作.為什么?
It behaves as if the contentSize was the same as the frame. What's going on?
This started working when I turned off AutoLayout. Why?
推薦答案
我也遇到了同樣的問(wèn)題.UIScrollView 的自動(dòng)布局搞砸了.
I had the same problem. Auto Layout for UIScrollView is messed up.
解決方法:將 UIScrollView 中的所有內(nèi)容放入另一個(gè) UIView，并將該 UIView 作為 UIScrollView 的唯一子項(xiàng).然后你可以使用自動(dòng)布局.
Work around: Put everything in the UIScrollView into another UIView, and put that UIView as the only child of the UIScrollView. Then you can use Auto Layout.
如果接近尾聲的事情搞砸了(無(wú)論您的 UIScrollView 滾動(dòng)哪個(gè)方向的尾端)，請(qǐng)將最后的約束更改為盡可能低的優(yōu)先級(jí).
If things near the end is messed up (the end of whichever direction your UIScrollView scrolls), change the constraint at the end to have the lowest possible priority.
這篇關(guān)于UIScrollView contentSize 不起作用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)！
