Answer 1

olduğunu. Görünümü açtıktan (bir örnek oluşturduktan sonra), görünümü kapatıp (örnek bırakarak) ve ardından görünümü yeniden açtığınızda (ikinci bir örnek oluşturarak) gerçekleşir. Ve sorun addPayment: çağrısı içinde oluyor. Bu, çerçevenin eski, yayınlanan örneğinizde hala bir tanıtıcı olduğunu ve ona bir ileti göndermeye çalıştığını gösterir. Eğer bir gözlemci olarak self kaldırmak nerede yerde göremiyorum

[[SKPaymentQueue defaultQueue] addTransactionObserver:self]; 

çağırdığınızda

Sen loadStore da nesneye çerçevesinin bir kolu ver. Bildirimleri gönderen nesneler genellikle gözlemcilerini korumazlar, çünkü bunu yapmak bir koruma döngüsü ve/veya bir bellek sızıntısı oluşturabilir. senin dealloc kodunda

Eğer temizleme gerekiyor ve removeTransactionObserver: arayın. Bu, sorunu çözmeli.

Answer 2

AddTransactionObserver kullanılarak eklenen gözlemcilerin görünüşte zayıf referanslar olduğunu düşünüyorum - bunu açıklayan güçlü olanlar değil. Basit bir test yaptık: removeTransactionObserver'ı çağırmadan da aynı çöküşü kazandım.

@property (strong) MyObserver* observer; 
.... 
self.observer = [[MyObserver alloc] init]; 
addTransactionObserver(observer);
