my dsym file: dsym.

i run dwarfdump --arch=arm64 --lookup 0x429496857fc2 yixia.app.dsym , following result:

i'm sure code causes crash: crash code.

the app crashes after invoking + (nsdata *)generategifwithimage:(uiimage *)image andstickers:(nsarray *)stickers small:(bool)small withsharetype:(nsuinteger)sharetype, screenshot:

then iphone lost connection.

replace 

dwarfdump --arch=arm64 --lookup  0x429496857fc2 yixia.app.dsym

with

atos -arch arm64 -o yixia.app.dsym/contents/resources/dwarf/yixia 0x429496857fc2
