仅在运行iOS 8的xcode 8上运行EXC_BAD_ACCESS

Question

当从xcode 7 for iOS 8到10编译时,应用程序运行正常,但是当从xcode 8编译时,应用程序仅在iOS 8上正常工作,iOS 8上的应用程序崩溃,应用程序崩溃不一致.有时它会停在一个随机的UI元素,例如:

但更常见的是它会在主要时崩溃:

我已经启用了NSZombies,但我没有获得任何新信息.我也尝试打开地址消毒剂,它也会偶尔崩溃,但通常也会在主要方法:

thread #1: tid = 0x11d992, 0x020fce9e libclang_rt.asan_ios_dynamic.dylib`__asan::AsanDie(), queue = 'com.apple.main-thread', stop reason = Attempt to free a non-allocated address
{
"access_size" : 0,
  "access_type" : 0,
  "address" : 103442256,
  "description" : "Attempt to free a non-allocated address",
  "instrumentation_class" : "AddressSanitizer",
  "pc" : 0,
  "stop_type" : "fatal_error"
}

再次,当从Xcode 7或Xcode 8为iOS 9或10构建时,应用程序工作正常.这只发生在从iOS 8的Xcode 8构建时.任何想法？

使用Xcode 8 GM,如果您在针对iOS版本早于iOS 9.3的应用提交中包含16位或P3资源,则会出现此错误.如果您的应用需要广泛的颜色功能,则必须将部署目标更改为iOS 9.3或更高版本.如果您的应用程序不需要广泛的颜色功能,并且您希望将其部署到较旧的iOS版本,那么您应该用8位sRGB资产替换所有16位或P3资产.您可以通过在iTunes Connect的错误消息中指定的资产目录上运行"assetutil"来查找16位或P3资产.以下步骤概述了该过程:

1. 创建一个Inspectable .ipa文件.在Xcode Organizer(Xcode-> Window-> Organizer)中,选择要检查的存档,单击"Export ...",然后选择"Export for Enterprise或Ad-Hoc Deployment".这将创建一个本地副本.适用于您的应用的ipa文件.
2. 找到.ipa文件并将其扩展名更改为.zip.
3. 展开.zip文件.这将生成一个包含.app包的Payload文件夹.

4. 打开终端并将工作目录更改为.app包cd路径/到/ Payload/your.app的顶层

5. 使用find工具在.app包中找到Assets.car文件,如下所示:find.-name'Assets.car'

6. 使用assetutil工具在应用程序的每个Assets.car中查找任何16位或P3资产,如下所示.:sudo xcrun --sdk iphoneos assetutil --info /path/to/a/Assets.car> /tmp/Assets.json

7. 检查生成的/tmp/Assets.json并查找包含"DisplayGamut"的任何内容:"P3"及其关联的"名称".这将是包含一个或多个16位或P3资产的图像集的名称.

8. 用8位/ sRGB资产替换这些资产,然后重建您的应用程序.更新:如果您的部署目标设置为8.3或8.4并且您有资产目录,那么即使您实际上没有16位或P3资产,也会收到相同的错误消息.在这种情况下,您需要将部署目标降低到8.2,或将其移动到9.x.

更新: 如果您的部署目标设置为8.3或8.4并且您有资产目录,那么即使您实际上没有16位或P3资产,也会收到相同的错误消息.在这种情况下,您需要将部署目标降低到8.2,或将其移动到9.x.
