Launch an app from within another (iPhone)

People also ask

Can you launch an app from another app?

Using intents even allows your app to start an activity that is contained in a separate app. An Intent can be explicit in order to start a specific component (a specific Activity instance) or implicit in order to start any component that can handle the intended action (such as "capture a photo").

Can you run two of the same app on iPhone?

You can place multiple copies of the same app on your home screen with iOS 15. Here's a funny one: iOS 15 lets you place multiple copies of the same app on Springboard. This means you can have the same app duplicated across your home screens, as many times as you want.

How do I share apps between iphones?

Method 2: How to Send Apps from iPhone to iPhone by AirDrop Step 1. Select the apps on the old iPhone that you want to send to the new iPhone and hit the “Share” button then choose the destination iPhone. Step 2. On your new iPhone, tap “Accept” to allow Airdrop transfer selected apps from your old to the new iPhone.


As Kevin points out, URL Schemes are the only way to communicate between apps. So, no, it's not possible to launch arbitrary apps.

But it is possible to launch any app that registers a URL Scheme, whether it's Apple's, yours, or another developer's. The docs are here:

Defining a Custom URL Scheme for Your App

As for launching the phone, looks like your tel: link needs to have least three digits before the phone will launch. So you can't just drop into the app without dialing a number.


I found that it's easy to write an app that can open another app.

Let's assume that we have two apps called FirstApp and SecondApp. When we open the FirstApp, we want to be able to open the SecondApp by clicking a button. The solution to do this is:

  1. In SecondApp

    Go to the plist file of SecondApp and you need to add a URL Schemes with a string iOSDevTips(of course you can write another string.it's up to you).

enter image description here

2 . In FirstApp

Create a button with the below action:

- (void)buttonPressed:(UIButton *)button
{
  NSString *customURL = @"iOSDevTips://";

  if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:customURL]])
  {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:customURL]];
  }
  else
  {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"URL error"
                              message:[NSString stringWithFormat:@"No custom URL defined for %@", customURL]
                              delegate:self cancelButtonTitle:@"Ok" 
                              otherButtonTitles:nil];
    [alert show];
  }

}

That's it. Now when you can click the button in the FirstApp it should open the SecondApp.


The lee answer is absolutely correct for iOS prior to 8.

In iOS 9+ you must whitelist any URL schemes your App wants to query in Info.plist under the LSApplicationQueriesSchemes key (an array of strings):

In Swift

Just in case someone was looking for a quick Swift copy and paste.

if let url = URL(string: "app://"), UIApplication.shared.canOpenURL(url) {
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
        } else if let itunesUrl = URL(string: appLink), UIApplication.shared.canOpenURL(itunesUrl) {
            UIApplication.shared.open(itunesUrl, options: [:], completionHandler: nil)
        }
