I use the method to upload my custom backtrace
[[Crashlytics sharedInstance] recordCustomExceptionName:@"test" reason:@"error" frameArray:myArray];
in "myArray" have two address 0x10005f35b and 0x10005f1b7
on my macbook, i use "dwarfdump" to parse 0x10005f35b and 0x10005f1b7 can get correct symbol.
but i upload 0x10005f35b and 0x10005f1b7 to fabric, fabric cannot symbol 0x10005f35b
fabric result :
0x10005f35b (Missing)
0x10005f1b7 -[ViewController fabricStackTest:]
why fabric cannot parse address 0x10005f35b??
the same IPA file and same DSym file，i did upload DSym file to fabric
I solved this problem, it's my app bug, thank you
When you see "(Missing)" on Crashlytics UI, You can first check the memory offset is the same as fabric?
memory_offset = _dyld_get_image_vmaddr_slide(i)
_dyld_get_image_vmaddr_slide() returns the virtural memory address slide amount of the image indexed by image_index. If image_index is out of range zero is returned.
memory_offset is different in every app launch.
memory_address - memory_offset = file_address
file_address and .dSYM can corrent symbolicate a address.
my bug is i save memory_address to the file and next app launch, i pass to fabric SDK, next app launch the memory_offset is different, so fabric cannot symbolicate the address.
My Solution: I save file_address to the file, and next app launch, i do addition, file_address + memory_offset = now_address, i pass now_address to SDK, can corrent symbolication
