Добавьте это к делегату UIWebView:
(отредактировано для проверки типа навигации. Вы также можете пропустить file://
запросов, которые будут относительными ссылками)
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if (navigationType == UIWebViewNavigationTypeLinkClicked ) {
[[UIApplication sharedApplication] openURL:[request URL]];
return NO;
}
return YES;
}
Swift Версия:
func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if navigationType == UIWebViewNavigationType.LinkClicked {
UIApplication.sharedApplication().openURL(request.URL!)
return false
}
return true
}
Swift 3 версия:
func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if navigationType == UIWebViewNavigationType.linkClicked {
UIApplication.shared.openURL(request.url!)
return false
}
return true
}
Swift 4 версия:
func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebView.NavigationType) -> Bool {
guard let url = request.url, navigationType == .linkClicked else { return true }
UIApplication.shared.open(url, options: [:], completionHandler: nil)
return false
}
Обновление
Поскольку openURL
устарела в iOS 10:
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if (navigationType == UIWebViewNavigationTypeLinkClicked ) {
UIApplication *application = [UIApplication sharedApplication];
[application openURL:[request URL] options:@{} completionHandler:nil];
return NO;
}
return YES;
}
