我发现了一个非常适合我的方法(我稍微修改了一下):iphone UIImageView旋转

#import <QuartzCore/QuartzCore.h>

- (void) runSpinAnimationOnView:(UIView*)view duration:(CGFloat)duration rotations:(CGFloat)rotations repeat:(float)repeat {
    CABasicAnimation* rotationAnimation;
    rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
    rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 /* full rotation*/ * rotations * duration ];
    rotationAnimation.duration = duration;
    rotationAnimation.cumulative = YES;
    rotationAnimation.repeatCount = repeat ? HUGE_VALF : 0;

    [view.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];
}

我已经开发了一个闪亮的动画框架，可以节省你的时间! 使用它可以很容易地创建这个动画:

private var endlessRotater: EndlessAnimator!
override func viewDidAppear(animated: Bool) 
{
    super.viewDidAppear(animated)
    let rotationAnimation = AdditiveRotateAnimator(M_PI).to(targetView).duration(2.0).baseAnimation(.CurveLinear)
    endlessRotater = EndlessAnimator(rotationAnimation)
    endlessRotater.animate()
}

要停止这个动画，只需将nil设置为endlessRotater。

使用UIView执行360度动画有以下几种不同的方法。

使用CABasicAnimation

var rotationAnimation = CABasicAnimation()
rotationAnimation = CABasicAnimation.init(keyPath: "transform.rotation.z")
rotationAnimation.toValue = NSNumber(value: (Double.pi))
rotationAnimation.duration = 1.0
rotationAnimation.isCumulative = true
rotationAnimation.repeatCount = 100.0
view.layer.add(rotationAnimation, forKey: "rotationAnimation")

下面是UIView的一个扩展函数，它处理启动和停止旋转操作:

extension UIView {

    // Start rotation
    func startRotation() {
        let rotation = CABasicAnimation(keyPath: "transform.rotation.z")
        rotation.fromValue = 0
        rotation.toValue = NSNumber(value: Double.pi)
        rotation.duration = 1.0
        rotation.isCumulative = true
        rotation.repeatCount = FLT_MAX
        self.layer.add(rotation, forKey: "rotationAnimation")
    }

    // Stop rotation
    func stopRotation() {
        self.layer.removeAnimation(forKey: "rotationAnimation")
    }
}

现在使用UIView。动画关闭:

UIView.animate(withDuration: 0.5, animations: { 
      view.transform = CGAffineTransform(rotationAngle: (CGFloat(Double.pi)) 
}) { (isAnimationComplete) in
    // Animation completed 
}

我认为你最好添加一个UIVIew Category:

#import <QuartzCore/QuartzCore.h>
#import "UIView+Rotate.h"

实现UIView(旋转)

(void)remrotate360WithDuration:(CGFloat)duration repeatCount: (float)repeatCount { CABasicAnimation *fullRotation; fullRotation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"]; fullRotation.fromValue = [NSNumber numberWithFloat:0]; fullRotation.toValue = [NSNumber numberWithFloat:(2*M_PI)]; // fullRotation.toValue = [NSNumber numberWithFloat:-(2*M_PI)]; // added this minus sign as i want to rotate it to anticlockwise fullRotation.duration = duration; fullRotation.speed = 2.0f; // Changed rotation speed if (repeatCount == 0) fullRotation.repeatCount = MAXFLOAT; else fullRotation.repeatCount = repeatCount; [self.layer addAnimation:fullRotation forKey:@"360"]; }

不使用此方法:)

(void)remstopAllAnimations { [self.layer removeAllAnimations]; }; (void)rempauseAnimations { [self rempauseLayer:self.layer]; } (void)remresumeAnimations { [self remresumeLayer:self.layer]; } (void)rempauseLayer:(CALayer *)layer { CFTimeInterval pausedTime = [layer convertTime:CACurrentMediaTime() fromLayer:nil]; layer.speed = 0.0; layer.timeOffset = pausedTime; } (void)remresumeLayer:(CALayer *)layer { CFTimeInterval pausedTime = [layer timeOffset]; layer.speed = 1.0; layer.timeOffset = 0.0; layer.beginTime = 0.0; CFTimeInterval timeSincePause = [layer convertTime:CACurrentMediaTime() fromLayer:nil] - pausedTime; layer.beginTime = timeSincePause; }

这对我很管用:

[UIView animateWithDuration:1.0
                animations:^
{
    self.imageView.transform = CGAffineTransformMakeRotation(M_PI);
    self.imageView.transform = CGAffineTransformMakeRotation(0);
}];

你也可以用UIView和block做同样类型的动画。下面是一个类扩展方法，它可以以任何角度旋转视图。

- (void)rotationWithDuration:(NSTimeInterval)duration angle:(CGFloat)angle options:(UIViewAnimationOptions)options
{
    // Repeat a quarter rotation as many times as needed to complete the full rotation
    CGFloat sign = angle > 0 ? 1 : -1;
    __block NSUInteger numberRepeats = floorf(fabsf(angle) / M_PI_2);
    CGFloat quarterDuration = duration * M_PI_2 / fabs(angle);

    CGFloat lastRotation = angle - sign * numberRepeats * M_PI_2;
    CGFloat lastDuration = duration - quarterDuration * numberRepeats;

    __block UIViewAnimationOptions startOptions = UIViewAnimationOptionBeginFromCurrentState;
    UIViewAnimationOptions endOptions = UIViewAnimationOptionBeginFromCurrentState;

    if (options & UIViewAnimationOptionCurveEaseIn || options == UIViewAnimationOptionCurveEaseInOut) {
        startOptions |= UIViewAnimationOptionCurveEaseIn;
    } else {
        startOptions |= UIViewAnimationOptionCurveLinear;
    }

    if (options & UIViewAnimationOptionCurveEaseOut || options == UIViewAnimationOptionCurveEaseInOut) {
        endOptions |= UIViewAnimationOptionCurveEaseOut;
    } else {
        endOptions |= UIViewAnimationOptionCurveLinear;
    }

    void (^lastRotationBlock)(void) = ^ {
        [UIView animateWithDuration:lastDuration 
                              delay:0 
                            options:endOptions 
                         animations:^{
                             self.transform = CGAffineTransformRotate(self.transform, lastRotation);
                         } 
                         completion:^(BOOL finished) {
                             NSLog(@"Animation completed");   
                         }
         ];
    };

    if (numberRepeats) {
        __block void (^quarterSpinningBlock)(void) = ^{ 
            [UIView animateWithDuration:quarterDuration 
                                  delay:0 
                                options:startOptions 
                             animations:^{
                                 self.transform = CGAffineTransformRotate(self.transform, M_PI_2);
                                 numberRepeats--; 
                             } 
                             completion:^(BOOL finished) {
                                 if (numberRepeats > 0) {
                                     startOptions = UIViewAnimationOptionBeginFromCurrentState | UIViewAnimationOptionCurveLinear;
                                     quarterSpinningBlock();
                                 } else {
                                     lastRotationBlock();
                                 }NSLog(@"Animation completed");   
                             }
             ];

        };

        quarterSpinningBlock();
    } else {
        lastRotationBlock();
    }
}
