How to open external link from UIWebView not in my App, but in Safari? SWIFT

问题

I would like to open all external links which are in my application (UIWebView) not inside the app, but in Safari. How can I do that? I have implement UiWebViewDelegate.

Working solution for my question bellow:

func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if navigationType == UIWebViewNavigationType.LinkClicked{
    UIApplication.sharedApplication().openURL(request.URL!)
    return false
}
    return true
}

@Leo Dabus thanks a lot for this hint, but I guess I have a better solution:

func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
    if navigationType == UIWebViewNavigationType.LinkClicked{
        UIApplication.sharedApplication().openURL(request.URL!)
        return false
    }
    return true
}

this one works perfect.

Solution for objective-c :- in ViewController.h

@interface ViewController : UIViewController<UIWebViewDelegate>

in ViewController.m

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
    if (navigationType == UIWebViewNavigationTypeLinkClicked){
        NSURL *url = request.URL;
        if ([[UIApplication sharedApplication] canOpenURL:url]) {
            [[UIApplication sharedApplication] openURL:url];
        }
        return NO;
    }
    return YES;
}
