Question

Ok I have an exsiting app that I am currently working on an update for. What I am trying to do is when the client updates their website, the app will pull the text from the certain page and display the text in an UITextView? I am trying this approach which works fine except it includes the text of the NavBar? So how do I get the text only and no NavBar?

   textView.text = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.innerText"];

Well you have two choices from the point i see it at. If you know how long the text in the nav bar is and it is the same character length just use:

NSString *webString = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.innerText"];
int length = amount of characters to remove from beginning of string;
webString = [webString substringFromIndex:length];

If you dont know the amount you want to remove you can use the NSScanner which is a bit more complicated but is more flexible.

NSString *webString = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.innerText"];
NSScanner *stringScanner = [NSScanner scannerWithString:webString];
NSString *content = [[NSString alloc] init];
while ([stringScanner isAtEnd] == NO) {

[stringScanner scanUpToString:@"Start of the text you want" intoString:null];
[stringScanner scanUpToString:@"End of the text you want" intoString:&content];
}

Hope This Helps 😀
