How to set initial zoom on UIWebView in xcode
提问by Ryan Stack
I'm wondering how to set an initial zoom on a PDF document loaded in a UIWebView in XCode. It is a table, and I want the web view to load zoomed in on a specific column (or part of a column which I can then scroll up and down). I've been reading and some people have pointed to this method - (NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)scriptbut I don't know exactly how this works.
我想知道如何在 XCode 的 UIWebView 中加载的 PDF 文档上设置初始缩放。它是一个表格，我希望 web 视图加载放大特定列（或列的一部分，然后我可以上下滚动）。我一直在阅读，有些人指出了这种方法，- (NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)script但我不知道它到底是如何工作的。
And while we're on the subject of PDFs, is there any way to scrape the PDF and turn it into usable strings?
当我们讨论 PDF 的主题时，有没有办法抓取 PDF 并将其转换为可用的字符串？
Edit:For reading a pdf, PDFBox is one possible solution. You have to import JAR files into your Xcode project. Here is a tutorial: http://www.oreillynet.com/pub/a/mac/2005/01/07/ipod_reader.html

UIWebView *webV = [[UIWebView alloc] init];
webV.scrollView.zoomScale = 4.0;
