How to Fix the "Presenting View Controllers on Detached View Controllers is Discouraged" Error in iOS 7

📱💥 Oh no, you have encountered the dreaded "Presenting view controllers on detached view controllers is discouraged" error in your iOS 7 app. Don't worry, we've got you covered! In this post, we'll delve into the common issues that can cause this error and provide easy solutions to fix it. So let's dive right in!

Understanding the Problem

When you see the "Presenting view controllers on detached view controllers is discouraged" error, it means that you are trying to present a view controller from a view controller that is not currently in the view hierarchy. This can happen when the view controller you are trying to present from has been deallocated or is not properly connected to the view hierarchy.

Common Causes of the Error

1️⃣ Deallocated View Controller: One common cause of this error is when the view controller you are trying to present from has been released from memory before the presentation happens. This can occur if you have a strong reference cycle or if you accidentally invalidate the view controller.

2️⃣ Disconnected View Hierarchy: Another cause can be that the view controller you are trying to present from is not connected to the main view hierarchy. This can happen if you are using custom view navigation or if you are presenting a view controller from a detached or orphaned view.

Easy Solutions

Now that we understand the problem, let's explore some easy solutions to fix it:

1️⃣ Check for Strong Reference Cycles: If you suspect that the view controller is being deallocated prematurely due to a strong reference cycle, use tools like Instruments to detect memory leaks. Make sure you properly weakify your references or use capture lists in closures to break the cycle.

2️⃣ Ensure Proper View Hierarchy: Verify that the view controller you are trying to present from is properly connected to the main view hierarchy. Check if you are presenting from a detached or orphaned view by reviewing your view controller hierarchy.

3️⃣ Use UINavigationController: If you are not using a UINavigationController, try embedding the view controller you are presenting from in one. This can ensure that the view controller remains connected to the view hierarchy throughout its lifecycle.
