내 코드에 2 가지 문제가 있으며 누군가 내가 문제 해결을 도울 수 있는지 알고 싶습니다. 내가 원하는 objective-c가있는 무한 회전식 컨베이어

여기 내 코드입니다
1) 첫 번째 문제는 회전 목마가 매우 느리게 왼쪽/오른쪽으로 이동한다는 것입니다. 시간을 변경하지만 여전히 파악하지 못했습니다 ??????
2) 뒤에서 회전 할 때 나는 여전히 회전 장치에서 단추를 볼 수 있습니다. 나는 0으로 알파를 설정하지만 여전히 볼 수 있습니다 ???? 나는 새로운 해요
목적은-C 내 실수에 대한 유감, 오브젝티브 -C는 C++
도움과 조언 바랍니다 매우 다릅니다 ???
