ios - How to find where the app is crashing? -


below logs:

on mac can find backtrace of crashes in console app under user diagnostic reports.

you cannot tell crash happening, since backtrace stripped out. either try compile code debug symbols, or use dtrace/dtruss debug app.

the objc_msgsend standard function of objective-c.
