问题 What is the reason that we cannot use the browser Back button when we submit a page using HTTP POST? But it is fine with HTTP GET? I have read that the browser tries to prevent multiple POSTS (to avoid multiple updates to server) because it cannot tell the difference between BACK and RELOAD on the browser? How can browser not tell between BACK and RELOAD? 回答1: Back isn't a special request that goes to the server. Back just navigates to the previous page, same as if you just entered the url in

问题 I'm trying to write an app that detects key presses. I have tried all kinds of different types of apps and no success.

由 纵然是瞬间 提交于 2019-12-07 06:40:18
问题 I'm having this problem in my iPhone app: I have a webView which is first loaded with an HTML string. After the user clicks a link and it loads the requested page, the webView won't go back when I call the method [UIWebView goBack]; I suppose webView doesn't cache the HTML string. Is there any way I can make webView cache my HTML string without having to save it in a NSString myself? 回答1: You can use the canGoBack property and if you can't go back, reload the UIWebView with the original html.

问题 I'm trying to figure out how to create a back button that allows the user to go back one page. I read through Apple's Docs (which still go way over my head) and found out that I need to setup the canGoBack and goBack 's. I have tried this, but for some reason it is not working.
