问题描述
我正在开发一个应用程序，在iPhone文件系统上本地保存html文件，然后在UIWebView中加载它们。我希望能够在UIWebView上以编程方式缩放或双击，我尝试搜索javascript代码，但我只能滚动。
I'm developing an app that saves html files locally on iPhone file system, then load them in UIWebView. I want to be able to zoom or double tap programmatically on the UIWebView, I tried searching for javascript code, but I could only scroll.
我还尝试了webview转换，但没有为我工作。
我发现这个方法
I also tried the webview transform, but didn't work out for me.I found this method
sendAction:to:from:forEvent:
，可以将动作发送到控件。
in the UIApplication class, that can send actions to controls.
是否有人知道如何以编程方式将双击操作发送到UIWebView在某个x，y？
Does anybody know how to send the double tap action programmatically to a UIWebView on a certain x,y?
推荐答案
获取UIWebview的子视图，这是一个UIScrollview
get the UIWebview's subview which is a UIScrollview
UIScrollView *sview = [[webview subviews] objectAtIndex:0];
然后使用缩放方法。
