-(ibaction)duckaction:(id)sender{      cabasicanimation *moveduck = [cabasicanimation animationwithkeypath:@"position"];     [moveduck setremovedoncompletion:yes];     [moveduck setduration:.40];     [moveduck setrepeatcount:1];     [moveduck setautoreverses:no];     [moveduck setfromvalue:[nsvalue valuewithcgpoint:                                  cgpointmake(btnduck.center.x+25 ,btnduck.center.y)]];     [moveduck settovalue:[nsvalue valuewithcgpoint:                                cgpointmake(btnduck.center.x -25, btnduck.center.y)]];     [btnduck.layer addanimation:moveduck forkey:@"position"];  }  -(ibaction)frogaction:(id)sender{     ptfrog = btnfrog.center;      [uiview animatewithduration:1.00                           delay:0.0                         options:(uiviewanimationoptionautoreverse|uiviewanimationoptionallowuserinteraction)                      animations:^ {                          cgpoint position;                          position.y = 577.0f;                          position.x = 58.0f;                          btnfrog.center = position;                      }                      completion:^(bool finished){                          btnfrog.center = ptfrog;                       }]; }

i have 2 buttons close each other. first press frog button press duck button @ end of frog animation there blink in frog button. not know why happening? how remove blinking?

remove line in completion block dude.

 btnfrog.center = ptfrog;

after animation completed center it.that reason blinking. if want set center put above code in animations block

updates:

-(ibaction)frogaction:(id)sender{     ptfrog = btnfrog.center;      [uiview animatewithduration:1.00                           delay:0.0                         options:(uiviewanimationoptionautoreverse|uiviewanimationoptionallowuserinteraction)                      animations:^ {                          cgpoint position;                          position.y = 577.0f;                          position.x = 58.0f;                          //btnfrog.center = position;                           btnfrog.center = ptfrog;                       }                      completion:^(bool finished){                       }]; }
