SubView kaldırırken CALayer Zombie

Detay Görünümüm var. Değerlerden biri, bir resme işaret eden bir URL'dir.

URL boş değilse, ilerleme çubuğunu görüntülemek için tempota bir Görünüm oluşturur ve görüntüyü arka planda NSURLConnection ile indirir. Hazır olduğunda, ilerlemeyi kaldırın ve eski ilerleme görünümünü değiştirerek foto yeni bir Görüntü Görünümü oluşturup ekleyin.

Görünümü [[self.view viewWithTag: 1100] removeFromSuperview]; ile kaldırmaya çalışırken EXC_BAD_ACCESS olarak her zaman alıyorum. . Kodu her satırda kontrol ettim ve hatanın nerede olduğunu tahmin edemiyorum belki de bazı kuralları kaçırdım.

Aletler bana şu bilgileri veriyor:

#   Address Category    Event Type  RefCt   Timestamp   Size    Responsible Library Responsible Caller
