动画annotationViews（循环动画），didSelectAnnotationView 不起作用答案

【问题描述】：

所以我尝试使用以下代码为我的 annotationViews 设置动画：

   - (void)mapView:(MKMapView *)mapView
didAddAnnotationViews:(NSArray *)annotationViews

{
    LLAnnotationView *aV;

    for (aV in annotationViews) {

        // Don't pin drop if annotation is user location
        if ([aV.annotation isKindOfClass:[MKUserLocation class]]) {
            continue;
        }

        aV.transform = CGAffineTransformMakeScale(0, 0);
        aV.alpha = 0.1;

        dispatch_async(dispatch_get_main_queue(), ^(void){
        [self animateAnnotationView:aV withAnnotationViews:annotationViews];
        });


       }
    }

-(void)animateAnnotationView:(LLAnnotationView*)aV withAnnotationViews:(NSArray*)annotationViews{

#define kDurationBetweenShowUpAnimations 0.4
#define kLoopAnimationDuration 1
#define kAnimationDuration 0.4

    // Initial animation

    [UIView animateWithDuration:kAnimationDuration delay:kDurationBetweenShowUpAnimations*[annotationViews indexOfObject:aV]options:UIViewAnimationOptionCurveLinear animations:^(void){

        aV.transform = CGAffineTransformMakeScale(1.1, 1.1);
        aV.alpha = 1.0;

    }completion:^(BOOL finished){
        [UIView animateWithDuration:kAnimationDuration/2 animations:^(void){

            aV.transform = CGAffineTransformMakeScale(1.0, 1.0);
            aV.alpha = 0.9;

        }completion:^(BOOL finished){

            [UIView animateWithDuration:kAnimationDuration animations:^(void){

                aV.transform = CGAffineTransformMakeScale(1.1, 1.1);
                aV.alpha = 1.0;
            }completion:^(BOOL finished){

                // **LOOP animation**

                [UIView animateWithDuration:kLoopAnimationDuration delay:0 options:UIViewAnimationOptionRepeat | UIViewAnimationOptionAutoreverse animations:^(void){

                    aV.transform = CGAffineTransformMakeScale(1.0, 1.0);
                    aV.alpha = 0.9;
                }completion:^(BOOL finished){

                }];
            }];
        }];

    }];
}

关于动画，一切正常。但是当我尝试选择一个注释视图时，didSelectAnnotationView 很少被调用。

我怀疑这应该与线程相关。

有人知道发生了什么吗？？

谢谢。

【解决方案1】：

刚刚找到解决方案。将 UIViewAnimationOptionAllowUserInteraction 添加到 animateWithDuration 的选项中：

[UIView animateWithDuration:kLoopAnimationDuration 延迟：0 选项：UIViewAnimationOptionRepeat | UIViewAnimationOptionAutoreverse | UIViewAnimationOptionAllowUserInteraction ...

！！
