objective c - NSUserdefault not saving value ios9.3 , ios 10 , using side navigation -


this issue has been cause of lots of frustration , nsuserdefaults stopped working. saving facebook information in userdefaults later use , returning nil. note : nil when try slide in side navigation (using swrevealviewcontroller) bar.

here code :

[[nsuserdefaults standarduserdefaults] setvalue:[nsstring stringwithformat:@"%@",[resparray valueforkey:@"image_url"]] forkey:@"profilepic"];          [[nsuserdefaults standarduserdefaults] synchronize];

what have tried : - add/remove synchronize - clearing nsuserdefaults app - using setobject , setvalue nsuserdefault key - using nsstring stringwithformat , retrieving strings.

i tried each , every solution available on , web.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
