title: how to check whether application is installed or not in iOS device?
body: <p>I am doing one iOS application. In that, I have one module for UITableView. In that UITableView, I am displaying some list of apps names. Those names are coming from my server. Those are my company applications. So, i don't know how many apps would come from server. Once user clicks on the UITableViewCell, I need to check whether that apps already installed or not on that device. If not installed, user needs to goes to appstore using app store link of that app. I have checked some tutorials. In that they said, using url schemes we can do this scenario. But, i don't have url schemes for those urls, because those apps are coming from server. Also, I tried with following methods</p>
  
  <pre><code>[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms://itunes.com/apps/nameOfMyApp"]]; 
  [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"nameOfMyAppOrurl:"]];
  </code></pre>
  
  <p>but nothing helped me. Can anyone idea about this issue, if so please give your valuable suggestions.</p>
