xcode4.2

I have the following method in a NSDictionary category, to do a deep copy, which works fine. I just upgraded from Xcode 4.1 to 4.2, and the Analyze function gives two analyzer warnings for this code, as indicated: - (id)deepCopy; { id dict = [[NSMutableDictionary alloc] init]; id copy; for (id key in self) { id object = [self objectForKey:key]; if ([object respondsToSelector:@selector(deepCopy)]) copy = [object deepCopy]; else copy = [object copy]; [dict setObject:copy forKey:key]; // Both -deepCopy and -copy retain the object, and so does -setObject:forKey:, so need to -release: [copy release

I keep searching, but cannot find a clear and simple explanation on how to include one XCode project, along with all of it's sub-classes into another project. I routinely see stuff like that in sample projects that I download off the web, but do not know how to do this myself.

The segue does not work, seems like the second storyboard is not being loaded completely. Has

I'm currently developing an app for iPad. The development started for iOS 4.2 and is now continuing (and I think will be completed) for iOS 4.3. I just read about ARC in iOS 5, and basically I understood that we will never need to release and retain objects anymore. My questions are: If I decide to upgrade to iOS 5, do I need to remove all [myObject retain] and [myObject release] statements from my code? If I develop a new app for iOS 5 using ARC, will I need to implement some sort of "retro-compatibility" checks? i.e.: will I need to check the version of iOS and call retain and release
