我想处理endTurnWithNextParticipants失败的错误情况。因此，我在本文最后通过调用cacheFailedEndTurnWithNextParticipants方法来存储匹配数据。我提供的功能仅供参考。重试endTurnWithNextParticipants
问题是我不知道如何恢复uncache方法中的数据。我如何为下一个参与者列表加载GKTurnBasedPlayers？我用GKPlayer::loadPlayersForIdentifiers现在，但我得到以下警告：
"/Users/eternity/Documents/Xcode/DominationSK/DominationSK/GKMatchCache.m:134:74: Incompatible pointer types sending 'NSArray<GKPlayer *> * _Nullable' to parameter of type 'NSArray<GKTurnBasedParticipant *> * _Nonnull'"
我如何可以加载ID的GKTurnBasedParticipants？
这个重发应该以另一种方式完成吗？
-(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
-(void)cacheFailedEndTurnWithNextParticipants:(GKTurnBasedMatch*)match
participants:(NSArray<GKTurnBasedParticipant*>* _Nonnull)nextParticipants
turnTimeout:(NSTimeInterval)timeout
matchData:(NSData* _Nonnull)matchData
error:(NSError* _Nonnull)error
{
if ([self shallBeCached:error])
{
NSMutableArray *playerIds = [[NSMutableArray alloc] init];
for (GKTurnBasedParticipant *p in nextParticipants)
{
[playerIds addObject:p.player.playerID];
}
NSDictionary *d = @{MATCH_ID : match.matchID,
PARTICIPANTS : playerIds,
TIMEOUT : [NSNumber numberWithLong:timeout],
DATA : matchData};
[self addToCache:d];
}
}
