My xcode mapview wont work when combined with webview
- by user1715702
I have a small problem with my mapview. When combining the mapview code with the code for webview, the app does not zoom in on my position correctly (just gives me a world overview where i´m supposed to be somewhere in California - wish I was). And it doesn´t show the pin that I have placed on a specific location.
These things works perfectly fine, as long as the code does not contain anything concerning webview.
Below you´ll find the code. If someone can help me to solve this, I would be som thankful!

region.span.latitudeDelta = 0.01f;

[_mapView setRegion:region animated:YES];
newClass *ann = [[newClass alloc] init];
ann.title = @"Hjem";
ann.subtitle = @"Her bor jeg";
ann.coordinate = region.center;
[_mapView addAnnotation:ann];
NSString *urlAddress = @"http://google.no";
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlAddress];

//Load the request in the UIWebView.
[webView loadRequest:requestObj];
