核心代码

1.创建动画

JAVA

/**
* 创建缩放动画
*/
private Animation createScaleAnimation() {
    ScaleAnimation scaleAnimation = new ScaleAnimation(1f, 2f, 1f);
    scaleAnimation.setDuration(2000);   // 动画播放时间
    scaleAnimation.setRepeatCount(2000);
    scaleAnimation.setRepeatMode(Animation.RepeatMode.RESTART); // 动画重复模式
    scaleAnimation.setAnimationListener(new Animation.AnimationListener() {
        @Override
        public void onAnimationStart() {
        }

        @Override
        public void onAnimationEnd() {
        }

        @Override
        public void onAnimationCancel() {
        }

        @Override
        public void onAnimationRepeat() {
        }
    });
    return scaleAnimation;
}

mMarker.cancelAnimation();
mMarker.setAnimation(mAnimation);
mMarker.startAnimation();            
}

2.初始化view，设置动画控制监听

JAVA

private void initView() {
    mMapView = findViewById(R.id.mapview);
    mAddAniLayout = findViewById(R.id.add_ani);
    mAddAniLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mMarker.cancelAnimation();
            mMarker.setAnimation(mAnimation);
            mMarker.startAnimation();
        }
    });

    mRemoveAniLayout = findViewById(R.id.remove_ani);
    mRemoveAniLayout.setOnClickListener(new View.OnClickListener() {
        /**
            * Called when a view has been clicked.
            *
            * @param v The view that was clicked.
            */
        @Override
        public void onClick(View v) {
            mMarker.cancelAnimation();
            mMarker.setScale(1.0f);
        }
    });
}

接口

描述

- (instancetype)init

创建点标记实例

BMKPointAnnotation

CLLocationCoordinate2D coordinate;

设置点标记经纬度坐标

NSString *title;

设置显示的标题

BMKPinAnnotationView

- (id)initWithAnnotation:(id<BMKAnnotation>)annotationreuseIdentifier:(NSString *)reuseIdentifier;

初始化并返回一个BMKPinAnnotationView实例

BMKMapView

- (void)addAnnotation:(id <BMKAnnotation>)annotation;

向地图窗口添加点标记

CABasicAnimation

+ (instancetype)animationWithKeyPath:(nullable NSString *)path;

基于CABasicAnimation完成缩放动画的添加，删除，暂停，恢复

核心代码

Objective-C

//添加动画
- (void)addAnimation {
    //缩放动画，按之前设置的锚点进行缩放
    CABasicAnimation *scaleAnimation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
    scaleAnimation.duration = 1;
    scaleAnimation.repeatCount = HUGE_VALF;
    scaleAnimation.autoreverses = YES;
    //保证app切换到后台动画再切回来时动画依然执行
    scaleAnimation.removedOnCompletion = NO;
    scaleAnimation.fromValue = @(1.0);
    scaleAnimation.toValue = @(1.3);
    [self.layer addAnimation:scaleAnimation forKey:@"scale-layer"];
}

//移除动画
- (void)removeAnimation {
    [self.layer removeAllAnimations];
}

//暂停动画
- (void)pauseAnimation {
    CFTimeInterval pausedTime = [self.layer convertTime:CACurrentMediaTime() fromLayer:nil];
    self.layer.speed = 0.0;
    self.layer.timeOffset = pausedTime;
}
    
//恢复动画
- (void)resumeAnimation {
    CFTimeInterval pausedTime = [self.layer timeOffset];
    self.layer.speed = 1.0;
    self.layer.timeOffset = 0.0;
    self.layer.beginTime = 0.0;
    CFTimeInterval timeSincePause = [self.layer convertTime:CACurrentMediaTime() fromLayer:nil] - pausedTime;
    self.layer.beginTime = timeSincePause;
}
