Open URL Schemes in IOS

Question

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 t

Answer 1

To know whether an app is installed or not

-(BOOL) isAppInstalled:(NSString *)appUrl{

return [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:appUrl]]; // @ is not needed as you are passing input of function as a parameter.
}

To know whether any app got installed or not, invoke this function

if( [self isAppInstalled:@"MyApp2://"]) {

     NSLog("The second app is installed");  //Perform your actions
 }

Remember to include the second app's url scheme in First Apps LSApplicationURLScheme in its Info.plist.
