iPhone - Get Position of UIView within entire UIWindow

📱💡 Getting the position of a UIView within the entire UIWindow can be a bit tricky, especially when dealing with complex views like UITableViewCells. But worry not, because I'm here to guide you through the process! Let's dive in and find an easy solution to this problem. 🤓

🔍🐞 The problem at hand is that the usual methods like view.center or view.frame only give you the position of the UIView relative to its immediate superview. However, you want to determine its position in the entire 320x480 coordinate system, regardless of its superview.

🤔💭 So, how can we achieve this? Well, there's a neat little trick we can use to get the desired result. We'll make use of the UIView's convert(_:to:) method.

✨✋ But hold on a sec, what does convert(_:to:) do? This handy method allows you to convert a point or a rectangle from one coordinate system to another. In our case, we want to convert the position of our UIView to the coordinate system of the UIWindow.

👨‍💻💡 So, here's how you can do it:

1. First, you need to find a reference to the UIWindow that your view is in. There are different ways to do this, depending on your app's structure. One common approach is to use the UIApplication.shared.keyWindow property.

2. Once you have a reference to the UIWindow, you can use the convert(_:to:) method to convert the UIView's frame or center coordinates to the coordinate system of the window. For example:

let windowRect = view.convert(view.bounds, to: UIApplication.shared.keyWindow)

Here, view.bounds represents the CGRect of the UIView relative to its own coordinate system, and UIApplication.shared.keyWindow is the target coordinate system we want to convert to.

🎉🎉 And voila! windowRect now holds the position of your UIView within the entire UIWindow. 🌟

👉💡 To clarify further, let's take an example. Imagine your UIView is inside a UITableViewCell, and you want to find its position within the window. You can follow the steps above, replacing view with the appropriate reference to your UITableViewCell.

📣📢 Now that you've got the solution, why not share it with others who might be facing the same issue? Sharing is caring! 🤗
