ios - Updating UIButton border color will delay? -


we using bluetooth communication send notification when connected main view controller, notification :

- (void) receiveblenotification:(nsnotification *) notification {      if ([[notification name] isequaltostring:@"bluetooth"])     {       //here log title right on time next happen after while       nslog(@"!!!!!!!");      l1.layer.bordercolor=[globals sharedglobals].maincolor.cgcolor;      l2.layer.bordercolor=[globals sharedglobals].maincolor.cgcolor;

so reason color changed 6 seconds after log.

is there way force change ?

solved :

  dispatch_async(dispatch_get_main_queue(), ^{                 //here update required ui             });
