我是 Objective-C 编程的新手.
我正在使用带有一些标签、图像和文本视图的 UIScrollView.
我已经关闭了自动布局,并且已经尝试开启(标题中描述的情况)和关闭(不滚动)调整滚动视图插图".
这是我在 viewDidLoad 中插入的内容:
[scroller setScrollEnabled:YES];[滚轮 setContentSize:CGSizeMake(320, 687)];
但我一定遗漏了一些非常简单的东西.
1...为什么UIScrollView在顶部留下空间
使用 Storyboard- 转到视图控制器 > 属性检查器 > 取消选中 Adjust Scroll View Insets 属性
With Code- 额外空间设置viewController
属性automaticallyAdjustsScrollViewInsets
为NO
,默认为是代码>.
self.automaticallyAdjustsScrollViewInsets = false;scroller.contentInset = UIEdgeInsetsZero;scroller.scrollIndicatorInsets = UIEdgeInsetsZero;scroller.contentOffset = CGPointMake(0.0, 0.0);

2...不滚动到底部
要使其滚动,请尝试在 contentSize
中使用较大的数字,例如 CGSizeMake(320, 1687)
.如果它有效,则意味着您没有将 contentSize
设置得足够大以容纳其所有内容.
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.
