iOS可点击单词(UILabel或UIbutton的) [英] iOS Clickable Words (UILabel or UIbutton's)

问题描述

我想在我的应用程序中创建一个只读文本区域，该区域允许用户单击任何单词，然后应用程序将其读出.但是，我对哪种方法最好是有些困惑.我看到两个选项，使用UILabel并创建一些方法来检测单击的区域，然后将其与该区域中的单词匹配，但这听起来很难实现.另一方面，我可以使用单词数组来创建UIbutton的列表.感谢Jason，我们将不胜感激任何建议和/或示例代码.

I'm wanting to create a read only text area in my app which allows the user to click on any word and the app reads it out. I am however a little confused on which method would be the best. I see two options, use a UILabel and create some method to detect the region clicked then match it to the word in that region but it sounds hard to implement. On the other hand I could use an array of words to create a list of UIbutton's. Any advice and/or sample code to help me would be much appreciated, thanks Jason.

注意:每个视图上约有30个字.

Note: Each view has about 30 words on it.

以下解决方案效果很好.对于其他想要使用此功能的人，这四行代码会将您的UIWebView设置为背景清晰，并禁止任何滚动或跳动.

The solution below works well. For anyone else wanting to use this, these four lines will set your UIWebView to have a clear background and disable any scrolling or bounce.

[[myWebView.subviews objectAtIndex:0] setScrollEnabled:NO];
[[myWebView.subviews objectAtIndex:0] setBounces:NO];
[myWebView setBackgroundColor:[UIColor clearColor]];
[myWebView setOpaque:NO]; 

还有一些方便的CSS，可以在用户按住链接时停止打开弹出窗口.

And some handy css to stop the open popup when a user presses and holds a link.

*{-webkit-touch-callout:none; -webkit-user-select: none;} 

推荐答案

您的文本区域有多大?如果很大，则为每个作品创建一个UIButton听起来有点费劲，以使文本正确地进行布局.

How big is your text area? If it's big then creating a UIButton for each work sounds like sa bit of effor to get the text to layout correctly.

我将使用UIWebView-使每个单词都像这样:

I would use a UIWebView - make each word like this :

<a href="wordpress://WORD1">WORD1</a> <a href="wordpress://WORD2">WORD2</a> <a href="wordpress://WORD3">WORD3</a>

并将您的视图控制器附加为webView的 UIWebViewDelegate委托.

and attach your view controller as the webView's UIWebViewDelegate delegate.

然后，您可以使用 webView:shouldStartLoadWithRequest:navigationType:委托方法:)

Then, you can intercept presses on each word using the webView:shouldStartLoadWithRequest:navigationType: delegate method :)
