i'm writing webgl game , curious if better performance wise implement game's events checking if should occur @ every update of requestanimationframe (using date.now() ) or setting timeouts (using settimeout() ). note events 100ms apart. my major concern settimeout not waste cpu when idle (waiting next event) , if check @ every update ill doing computations wouldn't happen if using settimeout if need events, create events , use eventlisteners. if need check @ every call of raf condition has changed perform action, checks in raf loop. note : don't need , should avoid creating new date object @ each call ; there timestamp passed argument of requested function through raf, use this. function update(timestamp){...}; requestanimationframe(update); using settimeout @ high rate make useless call timedout function pushed on top of stack of tasks perform. embedding checks @ top of raf loop good.

previously, code developed fetch file content http url " http://storage.googleapis.com/abc ". but, requirement has got changed , demands instead of using http url link, should need use file directory location of server. (i.e., /var/puru/abc ). so, there proper or significant way , fulfill requirement without much-doing changes existing code drastically? i have provided code sample here, provide file url(baseurl) using http url actually. private url getfileurl(string filename) throws malformedurlexception { try { date dateobj = dateformatter.parse(date); calendar cal = calendar.getinstance(); cal.settime(dateobj); return new url(baseurl, cal.get(calendar.year) + "/" + filename); } catch (parseexception e) { e.printstacktrace(); } return null; } please suggest, , guide me.

in app there huge number of array lists. that's why have added arrays in 1 main array list, , have initialized them using "for" loop. i getting error inside "for" loop: "fast enumeration variables can't modified in arc default". nsmutablearray * mainarray = [[nsmutablearray alloc] initwithobjects:namearray, idarray, masteridnamearray, masteridarray, nil]; (nsmutablearray * array in mainarray) { array = [[nsmutablearray alloc] init]; } yes, can not modify values of array in fast enumeration, i.e. for(x in array) . object x becomes constant , hence through warning. however can use for(int i=0; i<[mainarray count]; i++) loop achieve this. but, wait: why want initialize after adding array. this: //first create arrays have, //namearray //idarray //masteridnamearray //masteridnamearray //then add them in mainarray nsmutablearray *namearray = [nsmutablearray array]; nsmutablearray *idarray = [nsmutablearr...

i'm guard ing call method may throw (a coredata fetch request), , @ same time i'm casting returned value specific type of array: guard let results = try? managedcontext.executefetchrequest(fetchrequest) as? [mymanagedobjectclass] else { // bail out if fetch or cast fails: return } the way understand that, because i'm using guard/try?/else (instead of do/try/catch ), else block (i.e. return statement) above executed if either of following occurs: the fetch request fails (and throw s) the fetch request succeeds casting of returned value [mymanagedobjectclass] fails. the code above works, after control passes guard check, variable results ends being of type [mymanagedobjectclass]? (" optional array of mymanagedobjectclass "). so if want -say- loop through array elements i have first unwrap it: if let results = results { // now, 'results' of type: // "(non-optional) array of mymanagedobjectclass" ele...
