實施Leadbolt廣告時的預期標識符錯誤

Question

我目前正在將LeadBolt插頁式廣告實施到我的iOS應用中。但是，在該行末尾：

[[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleModuleFail) name:@"onModuleFailed" object:@"AppFireworksNotification"]]; 

我收到「預期標識符」錯誤。請告知如何解決這個問題。

-(void)loadDisplayAd 
{ 
    LeadboltOverlay *interstitial = [LeadboltOverlay createAdWithSectionid:@"YOUR_LB_INTERSTITIAL_ID" view:self.view]; 
    [interstitial loadAd]; 
} 


- (void)viewDidLoad { 

    LeadboltOverlay *audioad = [LeadboltOverlay createAdWithSectionid:@"YOUR_LB_AUDIO_ID" view:self.view]; 
    [audioad loadAudioAd]; 
    // [AppTracker setLandscapeMode:YES]; // Un-comment for Landscape mode 
    [[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleModuleFail) name:@"onModuleFailed" object:@"AppFireworksNotification"]]; 
    [AppTracker startSession:@"APPFIREWORKS_API_KEY" view:self.view]; 


    [self loadDisplayAd]; 

Answer 1

您有一組額外的括號。有了這個

[[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleModuleFail) name:@"onModuleFailed" object:@"AppFireworksNotification"]]; 

：替換此

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleModuleFail) name:@"onModuleFailed" object:@"AppFireworksNotification"];
