iOS uiwebview goBack history control

Question

I am loading a \"webpage1\" on an uiwebview and saving its first request on an instance variable \"webviewHistory\". Then, I must reuse that webview to load another page, \"webp

Answer 1

UIWebviews have instance methods that allow you to go backwards and forwards with the history, without you having to track the last request. Is there a particular reason you are saving the last request specifically?

Sample code:

if ([webView canGoBack]) {
    [webView goBack];
}

Here is a project that is a simple uiwebview browser if you want to play with it: https://github.com/msencenb/UIWebView-Example

Answer 2

for swift 3 version of Msencenb answer:

if webView.canGoBack {
    webView.goBack()
}
