未安装应用程序时启动 Web 应用程序

Question

我希望能够在多个应用程序上共享内容。为此，我正在使用 URL Scheme。但如果没有安装该应用程序，我想启动相关应用程序的网页版。

像这样：

func share(urlScheme: String)
{
     if (UIApplication.sharedApplication().canOpenURL(NSURL(string:urlScheme)!))
     {
         UIApplication.sharedApplication().openURL(NSURL(string: string:urlScheme)!)
     }
     else
     {
         // open web version somehow
     }
}

我在这里添加了一些示例，用于 Uber 自定义您的自我，因为我们不知道您的 urlScheme 包含什么

例如

Swift

func share(urlScheme: String)
{
 if   (UIApplication.sharedApplication().canOpenURL(NSURL(string:"uber://")!))
 {

  // if your app is available it open the app 
     UIApplication.sharedApplication().openURL(NSURL(string: string:"uber://?openapp")!)
 }
 else
 {
     open web version somehow
    // it redirect to safari, safari directly open the web page on uber application, it does not redirect to app store

     UIApplication.sharedApplication().openURL(NSURL(string: string:"http://m.uber.com/?opneapp")!)
 }
}

Objective-C

 NSString *getUberDetails=[NSString stringWithFormat:@"client_id=vbtCwkGyqvDupQhpCcgCMo4VE-gIRw42&action=setPickup&pickup[latitude]=%f&pickup[longitude]=%f&pickup[nickname]=OuttAPP&dropoff[latitude]=%f&dropoff[longitude]=%f&dropoff[nickname]=%@&product_id=%@",[latitude floatValue],[longitude floatValue],[droplatitude floatValue],[dropLongtitude floatValue],[dropAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],[[huberTableArr objectAtIndex:indexPath.row]objectForKey:@"productID"]];


    if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"uber://"]])
    {


        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString  stringWithFormat:@"uber://?%@",getUberDetails]]];

    }
    else
    {
        [[UIApplication sharedApplication] openURL: [NSURL URLWithString:[NSString stringWithFormat:@"http://m.uber.com/?%@",getUberDetails]]];
    }
}
