Applicazione Crash per iOS: ZL36GetSFTrimCharSetForChineseOrJapanesePPK9TFontInfo_block_invoke

Question

Trovo nel mio XCode "Organizer" l'errore "ZL36GetSFTrimCharSetForChineseOrJapanesePPK9TFontInfo_block_invoke". Ho provato a impostare il mio iPhone in giapponese o cinese, ma l'errore non si verifica. Che cosa potrebbe causare questo errore e come posso risolverlo? Mi dispiace per il mio pessimo inglese.

Questo è il registro blocchi:

Answer 1

Sembra come un oggetto è stato deallocato, anche dopo aver avuto un riferimento a tale oggetto, quindi il codice per scontato che fosse valida. Prova a eseguire "Zombies" in Strumenti. Ti dirà dove hai inviato un messaggio a un oggetto non valido. Se si utilizza iOS Simulator, provare a eseguire Hardware -> Simula memoria avviso, il più frequentemente possibile durante il tentativo di riprodurre l'arresto anomalo.
