Question

我正在使用以下代码来检测是否在UIWebView中单击了链接并显示警报。因此用户需要确认离开应用程序。地址检测也有效。如果用户点击地址，您可以直接从Apple切换到Google地图应用。我想在切换到地图应用之前检测到这一点以显示警报。如何检测UIWebView中是否单击了地址（位置）？

-(BOOL) webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    savedLink = [request URL];
    if ( ( [ [ savedLink scheme ] isEqualToString: @"http" ] || [ [ savedLink scheme ] isEqualToString: @"https" ]) && ( navigationType == UIWebViewNavigationTypeLinkClicked ) ) {
        UIAlertView *leaveApp = [[UIAlertView alloc]initWithTitle:@"Warning!" message:@"You want to leave the app?" delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
        [leaveApp show];
        return NO;
    }
    return YES;
}


- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSString *title = [alertView buttonTitleAtIndex:buttonIndex];
    if([title isEqualToString:@"Yes"])
    {
        [[UIApplication sharedApplication] openURL:savedLink];
    }
    else if([title isEqualToString:@"No"])
    {
        //do nothing
    }
}

我期待像maps.apple.com这样的东西，但该方案被称为x-apple-data-detector。如果我正在寻找那个计划，它正在发挥作用。

[[savedLink scheme] isEqualToString:@"x-apple-data-detectors"]

如果在UIWebView中单击地址，则在切换到地图之前发出警报
