Detecting onclick on an ASP page on webView Objective C - ios

Question

I am using Classic ASP for my server page. When the following URL is loaded on webView. I will detect the link when user click on the webView using - (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType
If classbook.asp is detected when a new URL link is clicked on the webView, I will trigger a segue to load a new VC and load the new webView
However there is another google map link on the webView trigger by the following Classic ASP onclick code.
How do I detect when this google map link is clicked on the webView? Currently, the above method which is used to detect URL links cannot detect onclick
Server Classic ASP
<div id="map" onclick="window.open('http://maps.google.com/maps?q=<%=sLat%>,<%=sLongi%>(<%=sFCName%>)', '_system');"></div>
Objective C
#interface ClassesDet (){
AppDelegate *appDelegate;
NSString *sURL;
NSString *sURLFav;
}
#end
#implementation ClassesDet
#synthesize webView;
- (void)viewDidLoad {
[super viewDidLoad];
sURL = #"https://www.share-fitness.com/apps/class_det.asp?classcode=CLS100032&access=C&memcode=SF100035&catcode=YG&fccode=KL00059&dtpclass=24/04/2018&tpfrom=20:15&fav=false&lang=EN&encode=20a728210f0869f04aab6cf1682881816a36f0bd47cc894ac4d8dd22dd0ded24"
NSURL *url = [NSURL URLWithString:sURL];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
[webView setDelegate:(id<UIWebViewDelegate>)self];
[webView loadRequest:urlRequest];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
ClassBook *target = segue.destinationViewController;
if ([segue.identifier isEqualToString:#"ClassBook"]) {
NSLog(#" To ClassBook sURL : %#", sURL);
target.urlString = sURL;
} else {
NSLog(#" Else to Other VC and the sURL : %#", sURL);
target.urlString = sURL;
}
}
- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {
NSURL *URL = [request URL];
NSString *theString = [URL absoluteString];
NSRange match;
NSLog(#"The URL Clicked : %#", sURL);
match = [theString rangeOfString: #"classbook.asp"];
//---If the URL string does not contain classbook.asp meaning it is loading the webview.
if (match.location == NSNotFound) {
NSLog(#"Load the webView with this sURL : %#", sURL);
return YES; //---Load webview, the URL will be sURL nothing to do with theString
} else {
sURL = theString;
NSLog(#"Trigger the Segue ClassBook and pass the sURL : %# Over ",sURL );
//---Calling the following method will trigger the segue and redirect to another viewController.
[self performSegueWithIdentifier:#"ClassBook" sender:self];
return NO; //---Don't load the webview
}
}
#end

Answer 1

Check out this answer. The problem you're having is that shouldStartLoadWithRequest: doesn't get called on JavaScript window.open(). The answer at the link has one way of making sure your code gets called. I was thinking one of the delegate methods would catch this but now I don't see it. Perhaps I was thinking of WKWebView.

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if ([webView.request.URL.absoluteString containsString:#"http://maps.google.com/maps?q"]) {
//Your logic if require
}
else {
//Your logic if require
}
return YES;
}
