Crash on -[MBProgressHUD done]

[smajekp]

Hello, I have crash on my app on -[MBProgressHUD done]. I have this lib on my project from November 2016 and I never have any problem with MBProgressHud till now. On fabric I have many crashes on this method. All crashes are on iOS 11.

This is usage of your library on my project:

- (void)showWaitHUD {
    [self addSubview:self.progressHUD];
    [self.progressHUD showAnimated:YES];
}

- (void)hideWaitHUD {
    [self.progressHUD hideAnimated:YES];
}

static void *kProgressHUDKey;

- (MBProgressHUD *)progressHUD {
    MBProgressHUD *progressHUD = objc_getAssociatedObject(self, &kProgressHUDKey);
    if (!progressHUD) {
        progressHUD = [[MBProgressHUD alloc] initWithView:self];
    //custom view configuration here
        objc_setAssociatedObject(self, &kProgressHUDKey, progressHUD, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
    }
    return progressHUD;
}
