Question

I know in Android, there is a pretty reliable built-in system for notifying me of crashes that happen. They almost immediately write the stack trace and some other info into a Google doc. it works tremendously well.

I started researching the same thing for ios, and I am not finding anything similar that is equally effective. I read this article: Xcode storyboard: Why does the iPad storyboard show iPhone sized views?

but I am not sure if this is still the case. Could anyone recommend me what to use for crash reports that happen on user devices?

Thanks!

I’m using Flurry with an uncaughtExceptionHandler and GTMStackTrace

The exception handler can look like this:

void uncaughtExceptionHandler(NSException *exception) 
{
    @try 
    {
        NSString *fullBacktrace = GTMSBStackTraceFromException(exception);
        NSMutableString *backtrace = [NSMutableString stringWithUTF8String:""];
        NSArray *backtraceArray = [fullBacktrace componentsSeparatedByString:@"\n"];
        for (id entry in backtraceArray) 
        {
            NSRange testRange = [entry rangeOfString:[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleName"]];
            if (testRange.length)
            { 
                [backtrace appendString:entry];    
            }
        }

        NSCharacterSet *whitespaces = [NSCharacterSet whitespaceCharacterSet];
        NSPredicate *noEmptyStrings = [NSPredicate predicateWithFormat:@"SELF != ''"];

        NSArray *parts = [backtrace componentsSeparatedByCharactersInSet:whitespaces];
        NSArray *filteredArray = [parts filteredArrayUsingPredicate:noEmptyStrings];
        NSString *strippedBacktrace = [filteredArray componentsJoinedByString:@" "];   
        [FlurryAnalytics logError:@"uncaughtExceptionHandler"
                          message:[NSString stringWithFormat:@"%@", strippedBacktrace ? strippedBacktrace : @"no matching backtrace"]
                        exception:exception];
    }
    @catch (NSException *exception) 
    {
        NSLog(@"whoa!  could not handle uncaught exception!");
        [FlurryAnalytics logError:@"uncaughtExceptionHandler"
                          message:@"no matching backtrace"
                        exception:exception];
    }
}

Testflight has a good crash log too.
