在UIScrollView中滚动文本 [英] scroll the text inside a UIScrollView

问题描述

我有一个控制器视图，其中包括(图像和文本).

I have a controller view, that includes, (image, and text).

这两个组件位于 UIScrollView 中，图像为 UIImageView ，文本为 UITextView (已启用滚动).当我尝试滚动整个屏幕时，文本不会随之滚动，因为它具有自己的滚动.

the two components are in UIScrollView, the image is UIImageView, and the text is UITextView (scroll is enabled). while i am trying to scroll the whole screen, the text doesn't scroll with it, because it has its own scroll.

我需要的是使用整个屏幕滚动条滚动文本.(将文本的滚动与整个文本的滚动合并).

what I need is to scroll the text with the whole screen scroller. (Merge the scroll of the text with the scroll of the whole one).

我应该将文本类型更改为label而不是textview还是应该怎么做?

should I change the type of text to label instead of textview or what should I do exactly?

谢谢

推荐答案

如果在加载时分配了 UITextView 的文本，只需在 viewWillAppear:方法中添加此代码即可.

just add this code in you viewWillAppear: method if text to UITextView are assign at Load time..

yourTextView.frame = CGRectMake(yourTextView.frame.origin.x, yourTextView.frame.origin.y, yourTextView.frame.size.width, yourTextView.contentSize.height);
yourTextView.text=@"Your Text";
float fscrview = yourTextView.frame.origin.y + yourTextView.frame.size.height + 20;
yourScrollView.contentSize=CGSizeMake(320, fscrview);

例如.

yourTextView.delegate = self;
yourTextView.userInteractionEnabled = NO;
yourTextView.backgroundColor = [UIColor clearColor];
yourTextView.font = [UIFont fontWithName:@"Helvetica" size:12.0];
yourTextView.textColor = [UIColor whiteColor];
yourTextView.text = @"Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.<br />\r\nLorem ipsum dolor sit amet, consetetur sadipscing elitr.<br />\r\nLorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.

yourTextView.frame = CGRectMake(yourTextView.frame.origin.x, yourTextView.frame.origin.y, yourTextView.frame.size.width, yourTextView.contentSize.height);
float fscrview = yourTextView.frame.origin.y + yourTextView.frame.size.height + 20;
yourScrollView.contentSize=CGSizeMake(320, fscrview);
