performance - iOS app freezes when changing CLLocationManager accuracy, returning from background state -


i'm using cllocationmanager instance, while running in background.

to save device power, interchange between kcllocationaccuracythreekilometers , kcllocationaccuracybest

when restore app running background, cllocationmanager instance activates kcllocationaccuracybest, if it's not using accuracy.

however, there seems some kind of freezing 2~3 seconds, not responding user interaction.

if i'm not wrong in analysis, changing accuracy of cllocationmanager instance seems main cause.

can explain limitations should aware of, when changing cllocationmanager accuracies?

and, have kind of solution issue?
