[問題] 關於不同程式間的NSNotificationCenter
大家好
想請問一下
如果我在a程式裡面使用
NSNotificationCenter *nc_in_a = [NSNotificationCenter defaultCenter];
在b程式裡面使用
NSNotificationCenter *nc_in_b = [NSNotificationCenter defaultCenter];
A與B的bundle id不同
想請教一下
假設
a程式的code有
[nc_in_a addObserver: ..... name:@"same_name" ...];
b程式的code有
[nc_in_b addObserver: ..... name:@"same_name" ...];
nc_in_a 與 nc_in_b
是否會互相干擾呢
觀念不是很清楚的部分還請各位指導
謝謝

感謝大家回應
我改了一下問題
假設a裡面是
NSDistributedNotificationCenter* nc_in_a = [NSDistributedNotificationCenter
defaultCenter];
b裡面是
NSDistributedNotificationCenter* nc_in_b = [NSDistributedNotificationCenter
defaultCenter];
a程式的code有
[nc_in_a addObserver: ..... name:@"same_name" ...];
b程式的code有
[nc_in_b addObserver: ..... name:@"same_name" ...];
假設c程式
NSDistributedNotificationCenter* nc_in_c = [NSDistributedNotificationCenter
defaultCenter];
[nc_in_c postNotificationName:@"same_name" ..];
是不是a b 都會收到呢
看了說明是寫
Each task has a default distributed notification center that you access with
the defaultCenter class method. There may be different types of distributed
notification centers. Currently there is a single type—
NSLocalNotificationCenterType. This type of distributed notification center
handles notifications that can be sent between tasks on a single computer
我自己猜想這邊三個
nc_in_a
nc_in_b
nc_in_c
是同一個 會互相影響
(衍申的問題 想請教一下是否有辦法看到目前已經add的Observer)
還請大家指點
謝謝
