Question

Typical dealloc

Well it sucks. What about if I forget a property to dealloc?

Why can’t we have something like dealloc All properties

Worst of all, I sort of like the way viewControllers are handled now. We put a property and poof the dealloc is put. Can’t have that on normal classes ha?

- (void)dealloc
{
    [_window release];
    [__managedObjectContext release];
    [__managedObjectModel release];
    [__persistentStoreCoordinator release];
    [_MainBadgerApplication release];
    [_SettingsMiscelaneous release];
    [_theNearByIsiKota release];
    [Customcell release];
    [PhoneCC release];
    [searchViewController release];
    [_superTabBar release];
    [_SuperNavBar release];
    [pinNumberView release];
    [_lblForPinNumber release];
    [navController release];
    [NearbyShortcut release];
    [_searchListView release];
    [_searchNearView release];
    [LoadingView release];
    [super dealloc];
}

I am thinking of a macro where I can just do

myDealloc

and that will enumerate all properties and release them one by one or set them to nil (which is almost equivalent)

This looks like a horrible idea, so here is the code 😀 This will step through every object property on your code and send a release. I didn’t compile it, but it’s more or less like this.

#import <objc/runtime.h>

unsigned int propertyCount;
objc_property_t *properties = class_copyPropertyList([self class], &propertyCount);
for (unsigned int i = 0; i < propertyCount; i++)
{
    SEL sel = @selector(release);
    const char *attr = property_getAttributes(properties[i]);
    switch (attr[1]) {
        case '@':
            property_getName(properties[i]), objc_msgSend(self, sel)]
            break;
        default:
            break;
    }
}
free(properties);

You can wrap it in a C function and call it from your dealloc.
