PLCrashReporter - How to symbolicate crash data in-process?

Question

Is there a way to symbolicate the crash reports after we get the crash data?

Currently, this is what I'm doing in handleCrashReport method;

PLCrashReportTextFormat textFormat = PLCrashReportTextFormatiOS;

    /* Decode data */

    PLCrashReport *crashLog = [[PLCrashReport alloc] initWithData: data error: &error];
    if (crashLog == nil) {
        NSLog(@"Could not decode crash file :%@",  [[error localizedDescription] UTF8String]);
    } else {
        NSString* report = [PLCrashReportTextFormatter stringValueForCrashReport: crashLog withTextFormat: textFormat];
        NSLog(@"Crash log \n\n\n%@ \n\n\n", report);

        NSString *outputPath = [documentsDirectory stringByAppendingPathComponent: @"app.crash"];
        if (![report writeToFile:outputPath atomically:YES encoding:NSUTF8StringEncoding error:nil]) {
            NSLog(@"Failed to write crash report");
        } else {
            NSLog(@"Saved crash report to: %@", outputPath);
        }

    }

When i print this out on console; I get this.

Application Specific Information:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'This should crash the application.'

I want to symbolicate in-process If this is possible. Any ideas?

Thanks much in advance.

Answer 1

You can symbolicate the crash report in process, this requires three things:

1. You should do that on then next app start only.
2. You need the app symbols to be part of the binary, which increases its size by 30-50%
3. You will not get line numbers.

The latest version of PLCrashReporter is able to do that, but I would not recommend it and rather symbolicate it using the dSYM because it is way more helpful.
