如何从你的一个App发送通知给另一个App？ （例：搜狗输入法下载皮肤完成后使用皮肤） 注：搜狗输入法是App、而键盘是Extension
当你为你的App 添加 App Extension时，如果想在App 发送通知给 Extension或许这篇文章可以帮助你。
// 发送通知
- (void)postNotificaiton {
CFNotificationCenterRef notification = CFNotificationCenterGetDarwinNotifyCenter ();
CFNotificationCenterPostNotification(notification, CFSTR("<notificaiton name>"), NULL,NULL, YES);
}
// 接收通知
- (void)receiveNotification {
CFNotificationCenterRef notification = CFNotificationCenterGetDarwinNotifyCenter ();
CFNotificationCenterAddObserver(notification, (__bridge const void *)(self), observerMethod,CFSTR("<notificaiton name>"), NULL, CFNotificationSuspensionBehaviorDeliverImmediately);
}
void observerMethod (CFNotificationCenterRef center, void *observer, CFStringRef name, const void *object, CFDictionaryRef userInfo)
{
// Your custom work
}
// 移除通知
- (void)removeNotification
{
CFNotificationCenterRef notification = CFNotificationCenterGetDarwinNotifyCenter ();
CFNotificationCenterRemoveObserver(notification, (__bridge const void *)(self), CFSTR("<notificaiton name>"), NULL);
}
