Struct NotificationCenter 

pub struct NotificationCenter(/* private fields */);

An Objective-C notification center.

C++ equivalent: NS::NotificationCenter

Implementations

impl NotificationCenter

pub fn default_center() -> Option<Self>

Get the default notification center.

C++ equivalent: static class NotificationCenter* defaultCenter()

pub fn add_observer( &self, name: NotificationName, object: *mut Object, queue: *mut c_void, block: *const c_void, ) -> *mut Object

Add an observer with a block.

C++ equivalent: Object* addObserver(NotificationName name, Object* pObj, void* pQueue, ObserverBlock block)

Note: The block parameter is a raw pointer to an Objective-C block. Use with mtl_sys block types.

pub fn remove_observer(&self, observer: &Object)

Remove an observer.

C++ equivalent: void removeObserver(Object* pObserver)

pub unsafe fn from_ptr(ptr: *mut c_void) -> Option<Self>

Create a NotificationCenter from a raw pointer.

Safety

The pointer must be a valid Objective-C NSNotificationCenter object.
