endTurnWithNextParticipants我想处理失败的错误情况。cacheFailedEndTurnWithNextParticipants因此，我通过调用本文末尾的方法来存储匹配数据。我提供的功能仅供参考。
问题是我不知道如何在 uncache 方法中恢复数据。如何加载GKTurnBasedPlayersnextParticipants 列表？我GKPlayer::loadPlayersForIdentifiers现在使用，但收到以下警告：
"/Users/eternity/Documents/Xcode/DominationSK/DominationSK/GKMatchCache.m:134:74: Incompatible pointer types sending 'NSArray<GKPlayer *> * _Nullable' to parameter of type 'NSArray<GKTurnBasedParticipant *> * _Nonnull'"
如何GKTurnBasedParticipants从 ID 加载？
是否应该以另一种方式进行重新传输？
-(void)uncache
{
if (_cache.count > 0)
{
NSDictionary *d = _cache[0];
[_cache removeObjectAtIndex:0];
[GKTurnBasedMatch loadMatchWithID:d[MATCH_ID]
withCompletionHandler:^(GKTurnBasedMatch * _Nullable match, NSError * _Nullable error) {
if (error == nil)
{
bad load method --> [GKPlayer loadPlayersForIdentifiers:d[PARTICIPANTS]
withCompletionHandler:^(NSArray<GKPlayer *> * _Nullable nextParticipants, NSError * _Nullable error) {
if (error == nil)
{
NSNumber *timeout = d[TIMEOUT];
warning --> [match endTurnWithNextParticipants:nextParticipants
turnTimeout:timeout.longValue
matchData:d[DATA]
completionHandler:^(NSError * _Nullable error){
// This is not finished
}];
}
else
{
[self addToCache:d]; // TODO: Add time to live
}
}];
}
else
{
[self addToCache:d]; // TODO: Add time to live
}
}];
}
}
// Just for reference
