因使用AWS iOS SDK未捕獲的異常'NSInvalidArgumentException'而終止應用程序

Question

我在使用iOS SDK進行簡單的分段上傳到S3時遇到了問題。無法找出未被處理的參數異常，並且剩餘約65秒的背景時間（[UIApplication sharedApplication] .backgroundTimeRemaining）。這裏的日誌中的錯誤：

看看墜毀的這部分：

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** NSAllocateMemoryPages(4294967295) failed' 

您試圖在分配設備的內存4294967295字節，這是4GB。 NSAllocateMemoryPages
