ios – 在Swift中删除NSNotification的观察者？

因为viewDidUnload和dealloc()不可用,我应该在 Swift中删除NSNotification的观察者？

解决方法

使用下面的方法,其功能与dealloc相同.

deinit {
    // Release all recoureces
    // perform the deinitialization
}

A deinitializer is called immediately before a class instance is deallocated. You write deinitializers with the deinit keyword,similar to how intializers are written with the init keyword. Deinitializers are only available on class types.
