在IOS中打开URL方案 [英] Open URL Schemes in IOS

问题描述

我有2个应用程序，用于不同目的，我不应该允许用户在同一设备中使用这两个应用程序。如何检查是否安装了其他应用程序？
我想我可以使用Open URL来实现它，如下所示，将app bundle id设置为无效，我坚持为我的应用程序获取url
EX：fb：//

I have 2 apps, which are meant for different purpose, where I should not allow user to use both apps in same device. How can I check whether other app installed or not? I think I can do it using Open URL as following by putting app bundle id which is not working, I am stuck to get url for my app EX : "fb://"

       if ([[UIApplication sharedApplication] canOpenURL:@"My App URL"]) {
            //App installed
        }
        else{
            //App Not installed
        }
