Easily rearrange the UI controls of your view by describing the new layout in a different NIB.

MAZeroingWeakRef is a library for using zeroing weak references in retain/release Cocoa and Cocoa Touch code. These are references which do not keep an object alive, and which automatically become nil once the object is destroyed.

MAZeroingWeakRef does not work under Cocoa garbage collection. The built-in __weak specifier exists for that, although it is used somewhat differently.

The API is simple and mostly self-explanatory from the header file. Note that cleanup blocks are only needed for advanced uses when you need to take more action than simply zeroing the reference when the target object is destroyed. Be sure to heed the warning in the header about not doing too much work in the cleanup block.
