iOS get crash log

Although there is a try catch exception catch, there is still a crash exception that cannot be captured. I can get the crash log in the following way:

-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (Nsdictionary *) launchOptions {

Override point for customization after application launch.

Set exception Handling Handler

Nssetuncaughtexceptionhandler (&uncaughtexceptionhandler);

return YES;

}

void Uncaughtexceptionhandler (NSException *exception) {

The following code can get information about the crash exception

Nsarray *callstack = [exception callstacksymbols];

NSString *reason = [exception reason];

NSString *name = [exception name];

Processing of the collected crash logs, escalation of the server or prompting the user for mail delivery, etc...

}
