Memory leak when using MBProgressHUD

Question

I am using the MBProgressHUB as the loading indicter. I noticed via Instruments, There's considerable memory leak when using MBProgressHUB ( Around 3MB each time its initiate. And issue is, memory DOES NOT clear when the view unload ).

Project is ARC enabled

This is how I am initiate MBProgressHUB in ViewDidLoad (HUD is retained property too)

HUD = [[MBProgressHUD alloc] initWithView:[(AppDelegate *)[[UIApplication sharedApplication]     delegate] window]];
[[(AppDelegate *)[[UIApplication sharedApplication] delegate] window] addSubview:HUD];
HUD.delegate = self;

Also in the ViewDidUnload I am setting HUD = nil;

Any ideas???

Answer 1

I manage to solve the issue by Initializing MBProgressHUB only a single time in the AppDelegate. And use only a reference to that in other places

Answer 2

You are adding your hud to the window as subview. Window holds it in subviews all the time your app is running.

You should call [HUD removeFromSuperview] method when you don't need it or set property HUD.removeFromSuperViewOnHide to YES - so it will remove itself on hiding and deallocate the memory if you are not retaining it elsewhere.

If you added it to the controller's view - it would be deallocated in the end of controller's lifecycle with its view.

Answer 3

Im doing this with a non-ARC project.

I found a solution just changing the - (id)initWithView:(UIView *)view { method. It returns me and i changed it to return [me autorelease]
