问题描述
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);<块引用>
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.
