[英]Retry endTurnWithNextParticipants
我想處理endTurnWithNextParticipants
失敗的錯誤情況。 因此,我通過在本文結尾處調用cacheFailedEndTurnWithNextParticipants
方法來存儲匹配數據。 我提供的功能僅供參考。
問題是我不知道如何使用uncache方法還原數據。 我怎樣才能加載GKTurnBasedPlayers
為nextParticipants列表? 我現在使用GKPlayer::loadPlayersForIdentifiers
,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'"
如何從ID加載GKTurnBasedParticipants
?
重新傳輸是否應該以其他方式進行?
-(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];
}
}
可以從比賽中獲取參與者,然后從該數組中檢索玩家ID,最后更新比賽中的參與者屬性。
