Question

我发布了我的iOS应用程序的更新，AFAIK并没有改变我们处理推送通知的方式。

然而，我们的一部分用户报告发布时系统崩溃。 Fabric告诉我应用程序崩溃的原因是：

Fatal Exception: NSInternalInconsistencyException
Operation is invalid after previous operation.

并显示我在方法updateAgenciesChannels：

中将用户设置为默认推送频道时发生的情况

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];
}

它似乎与iOS版本无关（所有崩溃都发生在9.1.3上，但9.1.3上的很多用户都很好），它似乎也与设备类型无关
对于此用户子集，即使在再次删除/安装应用程序之后，崩溃仍然是系统化的，

以下是完整崩溃日志之一：

事实证明，当多次调用此方法时，我可能会尝试将用户置于某个频道，如果他已经被禁用（＆＃34;唯一对象＆＃34;已经在数组中），并试图取消注意如果用户已经没有被捕获（删除不在数组中的对象）
