shouldStartLoadWithRequest is not called when using AJAX/XMLHttpRequest
- by el_migu_el
Hi, I am trying to send method invocations from JavaScript to Objective-C and vice versa. Everything works fine for window.location triggered urls, which are catched by shouldStartLoadWithRequest. Now if I try to use an AJAX call instead, shouldStartLoadWithRequest is not called.
Is there a way to do this? Mainly I do not want to be restricted to the max URL size on data that can be passed from JavaScript to Objective-C.
My UIWebViewDelegate implements:
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
NSString *url = [[request URL] absoluteString];
NSRange urlrange = [url rangeOfString:@"myScheme://"];
if(urlrange.length > 0){
NSLog(@"this is an objective-c call, do not load link: %@", [url substringWithRange:NSMakeRange(urlrange.location, [url length])] );
return NO;
} else {
NSLog(@"not an objective-c call, load link: ", url );
return YES;
}
}
My JavaScript calls:
// works
window.location.href = "myScheme://readyHref";
// fails
var xmlHttpReq = false;
if (window.XMLHttpRequest) {
xmlHttpReq = new XMLHttpRequest();
} else if (window.ActiveXObject) {
xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlHttpReq.open('GET', "myScheme://readyAJAX", false);
xmlHttpReq.send();
