ios - compiling code with UrbanAirship libraries gives "release not available" error

Question

I added UrbanAirship libraries to my code, and I am getting these kinds of error when compiling UAPushSettingsAliasViewController.m and UAInboxMessageListCell.m and a few similar classes. The errors happen on this method:

- (void)dealloc {

    RELEASE_SAFELY(tableView);
    RELEASE_SAFELY(aliasCell);
    RELEASE_SAFELY(textCell);
    RELEASE_SAFELY(textLabel);
    RELEASE_SAFELY(aliasField);

    [super dealloc];
}

and most of the errors are "release not available: not available in automatic reference counting mode"

Would anyone know why this is happening and how I can resolve this?

Thanks, Alex

This is because you are using features such as dealloc, release and retain, which aren't needed in ARC as it automatically manages memory. You can turn off ARC in build settings, or add -fno-objc-arc to the compiler flags on the files that don't use ARC.

In build settings enter image description here

For the -fno-objc-arc, add it here

Add it by double clicking on compiler flags and add it for the files that contain things like retain, autorelease, release, and [super dealloc].

thanks, how do I acc that -fno-objc-arc to the compiler flags – Genadinik Mar 27 '13 at 22:58
thank you, that fixed most of the problems. There are still a few errors in UABeveledLoadingIndicator.m - would you know why that didn't get resolved? – Genadinik Mar 27 '13 at 23:11
@Genadinik what are the errors? – Chris Loonam Mar 27 '13 at 23:12
It says ARC forbids explicit message send of 'autorelease' – Genadinik Mar 27 '13 at 23:15
It seems that just in that file those autorelease and dealloc issues didn't go away. – Genadinik Mar 27 '13 at 23:16
Are you sure that you put the compiler flag on all the files that don't use ARC? – Chris Loonam Mar 27 '13 at 23:16
No, I just put it on the ViewController which you have on your example :) Should I go through my Controllers and test which are using the dealloc thing? – Genadinik Mar 27 '13 at 23:20
Yea, the ViewController was just an example. You have to put that flag on any file that manually manages memory, and shouldn't put it on files that do use ARC, as that may cause a problem. – Chris Loonam Mar 27 '13 at 23:22
