ios - Container App Crashing: More Information Needed from Crashlytics -


the development team work has produced container app serves client's mobile site. can see container app crashing on ios 10 don't have information cause of problem. stack trace doesn't point other possible issue webkit , js core:

nobody internal has been able app crash reliably (including test team using around clock) , far know, there no issues mobile site.

i've been asked issue @ bit of loss can't diagnose , fix if can't consistently break.

is there way more information crashlytics cause of crash?

mike fabric here , crashes can tough track down. you'd need release new version of app, there 3 different ways additional information.

1) add custom keys, example track pages being loaded or endpoints being hit, can provide additional context:

- (void)setobjectvalue:(id)value forkey:(nsstring *)key;  // calls -description on value, perfect nsstrings! - (void)setintvalue:(int)value forkey:(nsstring *)key;  - (void)setboolvalue:(bool)value forkey:(nsstring *)key;  - (void)setfloatvalue:(float)value forkey:(nsstring *)key;

2) add custom logs form of breadcrumbs make easier reproduce steps user doing in lead-up crash:

cls_log(@"user clicked on menu %@", attributesdict);

3) add user identifiers:

[crashlyticskit setuseridentifier:@"123456789"]; [crashlyticskit setuseremail:@"person@domain.com"]; [crashlyticskit setusername:@"awesome appuser"];

when else fails, reaching out user additional information can track down.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
