문제

UIImageview 애니메이션에 문제가 있습니다. 이미지가 포함 된 세 가지 NSARRAY 객체를 만들었고 UIIMAGEVIEW를 취하고 새로운 애니메이션을 할당하는 세 가지 방법을 만들었습니다. 그것은 처음으로 세 가지 방법 중 하나를 호출하지만 다른 시간에 시뮬레이터와 장치가 충돌합니다. 어떤 아이디어?

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {

// set the anims
slowAnimation = [NSArray arrayWithObjects:
                    [UIImage imageNamed:@"image1.jpg"],
                    [UIImage imageNamed:@"image2.jpg"],
                                nil];
defaultAnimation = [NSArray arrayWithObjects:
                    [UIImage imageNamed:@"image3.jpg"],
                    [UIImage imageNamed:@"image4.jpg"],
                        nil];
fastAnimation = [NSArray arrayWithObjects:
                    [UIImage imageNamed:@"image5.jpg"],
                    [UIImage imageNamed:@"image6.jpg"],
                    nil];

// load the default speed - this works once, but when applied a second time it crashes the simulator and device
[self setDefaultAnim:myUIImageViewObject];

[super viewDidLoad];
}


// animation switcher
-(void)setSlowAnim:(UIImageView *)imageView
{
    [imageView stopAnimating];
    imageView.animationImages = slowAnimation;
    imageView.animationDuration = 0.4;
    [imageView startAnimating];
}
-(void)setDefaultAnim:(UIImageView *)imageView
{
    [imageView stopAnimating];
    imageView.animationImages = defaultAnimation;
    imageView.animationDuration = 0.4;
        [imageView startAnimating];
}
-(void)setFastAnim:(UIImageView *)imageView
{
    [imageView stopAnimating];
    imageView.animationImages = fastAnimation;
    imageView.animationDuration = 0.4;
   [imageView startAnimating];
}

해결책

나는 당신이 필요하다고 생각합니다 retain 당신이 만든 세 배열 viewDidLoad - 당신은 결코 전화하지 않습니다 alloc 그들에게 전화 할 때까지 소유권이 없습니다. retain.

다른 팁

retain을 호출하는 대신 initwithobjects 메시지를 사용하십시오.

slowAnimation = [[NSArray alloc] initWithObjects:
                                  [UIImage imageNamed:@"image1.jpg"],
                                  [UIImage imageNamed:@"image2.jpg"],
                                  nil];

라운지가 제안한 것을 수행하면 나중에 슬로 니화 물체를 해제해야합니다. 당신이 그것을 할당했기 때문에, 누군가가 런타임을 말할 때까지 1의 유지 카운트가 있습니다.
