I am using @property(nonatomic, retain) for my IBOutlets for an iPhone application. However, I’m not sure how to make sure I’m managing memory with them properly. The IBOutlets are all set up in Interface Builder, so I’m never calling alloc manually. This means that I’m not sure when and if to deallocate them or when to set them to point to nil.
What are the best practices ensuring that no memory is leaked once the view unloads?
If you use @properties for yourIBOutlets and make the connections in IB then your controller is essentially retaining the IB objedcts with the property and is it therefore responsible for releasing them when it’s done with them.
When are you done with them?
In every case you should be setting your properties
self.propertyname = nilin yourviewDidUnloadmethod and again indeallocof each viewController.It’s quite straight forward, IB manages everything else.
