LayoutLoopHunter

The library helps to catch the OOMs caused by Autolayout Feedback Loop by replicating the behavior of UIViewLayoutFeedbackLoopDebuggingThreshold in the live code.

This is the final result of the runtime tutorial on AppCoda.

Installation

LayoutLoopHunter is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'LayoutLoopHunter'

and run pod install in your terminal.

Alternatively, you can manually add the files from the LayoutLoopHunter directory to your project.

Usage

Please use the setUp method to set up tracking for your UIView:

static func setUp(for view: UIView, threshold: Int = 100, onLoop: @escaping () -> ())

The callback will be called when the layoutSubviews() method is called a certain amount of times in a single run loop.

Example

LayoutLoopHunter.setUp(for: view) {
    print("Hello, world")
}

There's no Layout loop occur in example

I used the following example code in AppCoda


class ViewController: UIViewController {    
    override func viewDidLoad() {        
             super.viewDidLoad()         
            LayoutLoopHunter.setUp(for: view) {            
                   print("Hello, world")        
            } 
    }     
   override func viewDidLayoutSubviews(){       
          super.viewDidLayoutSubviews()        
          view.setNeedsLayout() // loop creation    
    }
}

but there's no layout loop occur when i execute this example. And layoutSubviews block was only executed two times.
