[英]ScrollView start scroll only second time that the view appear
I've a problem with my view in iOS7 with autolayout. 我在使用自动布局的iOS7中查看时遇到问题。
This is my structure: 这是我的结构:
The UITextView
content is dynamic so I fit his contentSize
dynamically in the viewDidLoad
. UITextView
内容是动态的,因此我将其contentSize
动态地适合在viewDidLoad
。
In my viewDidAppear
I try to fit the contentSize
of the MainScroll and the mother view calculated by the sum of UIScrollView
height (the little one), Pager height and UITextView
height. 在我的viewDidAppear
我尝试拟合MainScroll的contentSize
和由UIScrollView
高度(小),Pager高度和UITextView
高度之和计算的母视图。 I logged this height and it returned the correct size: 1300px but the view doesn't scroll. 我记录了这个高度,它返回了正确的大小:1300px,但视图没有滚动。
If I change tab and return here the scroll start to scroll, I've tried to put every piece of code in the viewDidLoad
but it doesn't work. 如果我更改选项卡并返回到此处,则滚动开始滚动,我试图将每段代码都放入viewDidLoad
但是它不起作用。

Try selecting it and then selecting "reset to suggested constraints" in the storyboard. 尝试选择它,然后在情节提要中选择“重置为建议的约束”。 :). :)。
