[ios] NSNotificationCenter 초간단 사용 예~ ㅋㄷ

Notification 날릴 때,

//Dictionary 만들어서 사용할 경우..
NSDictionary *infoData = [NSDictionary
    dictionaryWithObjectsAndKeys:missionIdString, @"missionId",
                          winYNString, @"winYNString",
                          str1String, @"str1String",
                          str2String, @"str2String",
                          callbackString, @"callbackString",
                          nil];

[[NSNotificationCenter defaultCenter]
    postNotificationName:@"NotificationLoadedBenefitView"
    object:nil userInfo:infoData];


// 또는 한번에.. ㅋㄷ
[[NSNotificationCenter defaultCenter]
    postNotificationName:@"NotificationLoadedBenefitView"
    object:nil userInfo:@{@"missionId":missionIdString,
                            @"winYNString": winYNString,
                            @"str1String": str1String,
                            @"str2String": str2String,
                            @"callbackString": callbackString}];

 

Notification 받는 방법과 처리하는 메소드(selector)

// Notification 처리 메소드
- (void)updateBenefitView:(NSNotification *)notification
{
    self.isWithCallback = YES;
    [self viewMissionResult:notification];
    
    NSDictionary *dict = [notification userInfo];
    NSString *callbackString = [dict objectForKey:@"callbackString"];

    [self performSelector:@selector(execCallback:)
        withObject:callbackString afterDelay:1.0];
}

// Notification 옵저버
- (void)viewDidLoad
{
    [[NSNotificationCenter defaultCenter]
        addObserver:self selector:@selector(updateBenefitView:)
        name:@"NotificationLoadedBenefitView" object:nil];
}

// Notification 제거
- (void)dealloc
{
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}
