In my Project, each of the user interaction events make a network call (Which is TCP, not HTTP). I need Activity Indicator to be global to show from a random UIViewController and hide from NetworkActivityManager Class (a custom class to handle network activities, Which is not a subclass of UIViewController or UIView).
After searching the web I found out that MBProgressHUD is used for the same purpose, but I wasn't able to find out an example on how would I use it globally. (By saying global I mean a singleton object of MBProgressHUD and class methods to SHOW and HIDE it.)
Following is what I have tried yet, but, failed: In AppDelegate.h:
@property (nonatomic, retain) MBProgressHUD *hud;
In AppDelegate.m:
@synthesize hud;
In some random UIViewController object:
appDelegate.hud = [MBProgressHUD showHUDAddedTo:appDelegate.navigationController.topViewController.view animated:YES];
appDelegate.hud.labelText = @"This will take some time.";
And while hiding it, from NetworkActivityManager Class:
[MBProgressHUD hideHUDForView:appDelegate.navigationController.topViewController.view animated:YES];
This makes the project to crash after some time (due to memory issues.) I am using ARC in my project and also, I am using the ARC version of MBProgressHUD.
Am I missing something?
Important Question:
Can I make MBProgressHUD work like UIAlertView? (Saying that I mean implementation of MBProgressHUD independent of UIView -- sa it uses showHUDAddedTo: to present itself) ???
Please Note: In the above code of hiding MBProgressHUD, View may be changed from what it was when showing MBProgressHUD.
Any Help greatly appreciated.
