ImageView动画,循环遍历图像

Question

所以我想在加载屏幕上设置UIImageView动画,我被告知内置的"animationImages"方法会占用大量内存并且编程错误所以我不会使用它,我也有问题但是除此之外.

下面的代码几乎可以工作,但即使我放了3秒,它的动画也太快了.

func animate() {

    UIView.animateWithDuration(3, animations: { () -> Void in

        self.logoImageView.image = UIImage(named: "00")
        self.logoImageView.image = UIImage(named: "02")
        self.logoImageView.image = UIImage(named: "03")
        self.logoImageView.image = UIImage(named: "04")
        self.logoImageView.image = UIImage(named: "05")
        self.logoImageView.image = UIImage(named: "06")
        self.logoImageView.image = UIImage(named: "07")
        self.logoImageView.image = UIImage(named: "08")
        self.logoImageView.image = UIImage(named: "09")
        self.logoImageView.image = UIImage(named: "10")
        self.logoImageView.image = UIImage(named: "11")
        self.logoImageView.image = UIImage(named: "12")
        self.logoImageView.image = UIImage(named: "13")
        self.logoImageView.image = UIImage(named: "14")
        self.logoImageView.image = UIImage(named: "15")
        self.logoImageView.image = UIImage(named: "16")
        self.logoImageView.image = UIImage(named: "17")
        self.logoImageView.image = UIImage(named: "18")
        self.logoImageView.image = UIImage(named: "19")
        self.logoImageView.image = UIImage(named: "20")
        self.logoImageView.image = UIImage(named: "21")
        self.logoImageView.image = UIImage(named: "22")
        self.logoImageView.image = UIImage(named: "23")
        self.logoImageView.image = UIImage(named: "24")
        self.logoImageView.image = UIImage(named: "25")
        self.logoImageView.image = UIImage(named: "26")

        }) { (success) -> Void in

            self.fadeInLabel()
    }

但是,下面的代码在欢迎标签中淡出并且工作正常,所以我想知道上面的问题是什么.谢谢您的帮助!

func fadeInLabel() {

    UIView.animateWithDuration(2, animations: { () -> Void in

        self.labelImageView.alpha = 1

        }) { (success) -> Void in

          self.performSelector("pushToCreateVC", withObject: self, afterDelay: 1)
    }

}

如果你想对图像进行动画处理，你可以使用animationImages以下属性UIImageView

self.logoImageView.animationImages = imagesListArray;
self.logoImageView.animationDuration = 3.0
self.logoImageView.startAnimating()

imagesListArray你想要制作动画的图像数组在哪里

或者

如果你想使用自定义动画为图像设置动画，你可以使用下面的代码，其中我使用了UIViewAnimationOptionTransitionFlipFromLeft动画选项。下面的代码位于 Obj-C 中，我希望你可以映射语义。

// in view Load
 _slide = 0
 [self changeSlide];

// Loop gallery 
NSTimer *timer = [NSTimer timerWithTimeInterval:5.0f target:self selector:@selector(changeSlide) userInfo:nil repeats:YES];
[[NSRunLoop mainRunLoop] addTimer:timer forMode:NSRunLoopCommonModes];


- (void)changeSlide
{

if(_slide > _galleryImages.count-1) _slide = 0;

UIImage *toImage = [UIImage imageNamed:_galleryImages[_slide]];
[UIView transitionWithView:_yourimageView
              duration:0.6f
               options:UIViewAnimationOptionTransitionFlipFromLeft
            animations:^{
                _yourimageView.image = toImage;

            } completion:nil];
_slide++;

}
