화면에 그려진 이미지를 제거하고 ARC가 회수 할 수 있도록 모든 링크를 해제하려면 어떻게해야합니까?

Question

나는 현재 메모리 누수가있는 애니메이션 시계를 가지고 있습니다. 나는 현재 이미지 위에 물건을 놓을 수있는 것처럼 보이지만 멀리 가져 가거나 반드시 지워서는 안됩니다 (초침이 다른 두 위치에 있지 않도록 시계 전체를 다시 그려야하는 것은 제외).

시계의 구성 요소를 삭제하기위한 코드는 다음과 같습니다

for(UIView *image in self.toWipe) 
{ 
    [image removeFromSuperview]; 
} 
[self.toWipe removeAllObjects]; 

초침을 그립니다 코드입니다 (시간과 분의 치료가 동일) :

CGAffineTransform secondTransform = CGAffineTransformMakeTranslation(centerX, centerY); 
secondTransform = CGAffineTransformTranslate(secondTransform, -10, -189); 
secondTransform = CGAffineTransformRotate(secondTransform, seconds/60.0 * M_PI * 2.0); 
UIImageView *secondHandView = [[UIImageView alloc] initWithImage:secondHandImage]; 
secondHandView.transform = secondTransform; 
[self.view addSubview:secondHandView]; 
[self.toWipe addObject:secondHandView]; 
[self.toWipe addObject:secondHandImage]; 

난을 가면 한 각 반복마다 시계면을 그려서 지우지 않는 그려진 초침; 그렇게하지 않으면 초침 (또는 다른 사람)이 360 ° 번 채워진 디스크에 도달 할 때까지 파이 조각을 날려 버릴 것입니다. 기억은 천천히 그러나 꾸준히 자랍니다. 그리고 두 번째 손은 움직임이 더 잘게됩니다.

사용 된 물건을 위탁하기 위해 내가 할 수 있거나해야 할 일이 있습니까? 이 프로젝트에서 ARC를 사용하고 있습니다. 나는 더 많이 또는 다르게 내가 줄 수있는 것을 알고 싶습니다. 그래서 메모리 누수가 수정되었습니다. cruft에 함께

감사

다음은, 주석 및 주석 cruft에이없는, 방법 체이다. 그것은 예외를 해결하지 않고, 예외는 몸에 아무것도에서 발생하지 않습니다 :

것은 그냥 제거하고 반복해서 이미지 뷰를 추가하는 대신 각 초 변환을 적용 봤어? 당신이 secondHandImage을 받고 어떻게 표시 할 수 있습니다, 그냥 호기심

-(void)updateClock 
{ 
    NSDateComponents *dateComponents = [[NSCalendar currentCalendar] components:(NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:inDate]; 
    NSInteger seconds = [dateComponents second]; 
    NSInteger minutes = [dateComponents minute]; 
    NSInteger hours = [dateComponents hour]; 
    //NSLog(@"raw: hours:%d min:%d secs:%d", hours, minutes, seconds); 
    if (hours > 12) hours -=12; //PM 

    //set angles for each of the hands 
    CGFloat secAngle = Degrees2Radians(seconds/60.0*360); 
    CGFloat minAngle = Degrees2Radians(minutes/60.0*360); 

    CGFloat minAdjustment = minAngle/12.0; 
    CGFloat hourAngle = Degrees2Radians(hours/12.0*360) + minAdjustment; 

    //reflect the rotations + 180 degres since CALayers coordinate system is inverted 
    secHand.transform = CATransform3DMakeRotation (secAngle+M_PI, 0, 0, 1); 
    minHand.transform = CATransform3DMakeRotation (minAngle+M_PI, 0, 0, 1); 
    hourHand.transform = CATransform3DMakeRotation (hourAngle+M_PI, 0, 0, 1); 
}
