PFAddUniqueOperation - 部分用戶的系統崩潰

我發佈了iOS應用的更新，AFAIK並未改變我們處理推送通知的方式。PFAddUniqueOperation - 部分用戶的系統崩潰

但是，我們的用戶的一個子集報告系統在啓動時崩潰。佈告訴我的應用程序崩潰是由於：

Fatal Exception: NSInternalInconsistencyException 
Operation is invalid after previous operation.

，並顯示在我suscribe用戶中的默認方法updateAgenciesChannels推渠道，它的存在的：

NSArray *agencies = [NSArray arrayWithObjects:@"channelA",@"channelB", nil]; 
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
PFInstallation *currentInstallation = [PFInstallation currentInstallation]; 

for(NSString *agency in agencies) 
{ 
    NSString *agencyString = [@"a-" stringByAppendingString:agency]; 
    BOOL agencyState = [defaults boolForKey:agencyString]; 
    if(agencyState) 
     [currentInstallation addUniqueObject:agencyString 
             forKey:@"channels"]; 
    else 
     [currentInstallation removeObject:agencyString 
             forKey:@"channels"]; 

    [currentInstallation saveInBackground]; 
}

這並不似乎是與iOS版本相關（所有崩潰都發生在9.1.3上，但很多9.1.3上的用戶都非常好），似乎也與設備類型無關。
對於用戶的這個子集，飛機墜毀系統，對所有發佈，甚至刪除/安裝應用程序後之後再次

事實證明，我試圖在多次調用此方法時嘗試將用戶訂閱到頻道，如果他已經訂閱（Array中已有「唯一對象」），並嘗試將用戶取消寫入頻道if他已經沒有認同（刪除對象不是我n陣列）
