ios - Resume download after app has been quit -

-

i wondering whether possible resume download after app has been terminated user or os.

i can see sktdownloadmanager has methods pause , resume download. however, these methods work current sktdownloadobjecthelpers. if pull them out of sktdownloadmanager.storeddownloadobjects() after app has been quit , started again , throw them @ sktdownloadmanager.sharedinstance().resumedownloadfordownloadhelper() manager won't resume downloads.

i dug little deeper code , these downloads not getting restarted because of lack of proper status. sktgroupeddownloadoperation.m:87:

if (self.currentrunninggroupedoperation.statedownloaditem >= sktmapdownloaditemstatusdownloading) {      return no; //cannot start download,isntall, finsihed }

so, questions whether possible resume downloads after app has been terminated , if how do it. appreciated :)

for resuming download, should trigger event in application:didfinishlaunching or after application restarted:

[[skdownloadmanager sharedinstance] tryrestartdownloadswithdelegate:self anddatasource:self];

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
