Question

我有一个大问题。我已将MKAnnotationView子类化，并为每个UIImageViews添加了一张图片。注释在地图上看起来很好。但是，它们不会捕获触摸事件。我尝试了self.userInteractionEnabled和exclusiveTouch周围的所有内容，但似乎没有任何效果。

（id）initWithAnnotation：（id）annotation reuseIdentifier：（NSString *）reuseIdentifier {

self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier];
self.frame = CGRectMake(0, 0, kWidth, kHeight);


UIImage *image = [UIImage imageNamed:@"geo-icon.png"];

UIImageView * turbineView = [ [ UIImageView alloc ] initWithFrame:CGRectMake(0.0, 0.0, image.size.width, image.size.height) ];

UIImageView * mastroView = [ [ UIImageView alloc ] initWithFrame:CGRectMake(20.0, 100.0, image.size.width, image.size.height) ];
mastroView.image = image;
mastroView.userInteractionEnabled = NO;
mastroView.exclusiveTouch = NO;


[turbineView addSubview:mastroView];

image = [UIImage imageNamed:@"turbine-noshadow.png"];
propellerView = [ [ UIImageView alloc ] initWithFrame:CGRectMake(4.0, 82.0, image.size.width, image.size.height) ];
propellerView.image = image;
propellerView.userInteractionEnabled = NO;
propellerView.exclusiveTouch = NO;
[turbineView addSubview:propellerView];

image = [UIImage imageNamed:@"arrow.png"];
UIImageView * arrowView = [ [ UIImageView alloc ] initWithFrame:CGRectMake(32.0, 114.0, image.size.width, image.size.height) ];
arrowView.image = image;
arrowView.userInteractionEnabled = NO;
arrowView.exclusiveTouch = NO;
[turbineView addSubview:arrowView];

image = [UIImage imageNamed:@"run-turbine.png"];
UIImageView * stoprunView = [ [ UIImageView alloc ] initWithFrame:CGRectMake(65.0, 155.0, image.size.width, image.size.height) ];
stoprunView.image = image;
stoprunView.userInteractionEnabled = NO;
stoprunView.exclusiveTouch = NO;
[turbineView addSubview:stoprunView];
turbineView.userInteractionEnabled = NO;
turbineView.exclusiveTouch = NO;




[self addSubview:turbineView];
self.userInteractionEnabled = NO;
self.exclusiveTouch = NO;
self.opaque = NO;

[self rodar];  //
return self;

}

使用MKMapViewDelegate的mapView:didSelectAnnotationView:来检测用户何时点击注释，而不是尝试与注释本身的点击进行交互。

您可以确定选择了哪些注释，并从mapView:didSelect...采取相应的操作。

注释视图中的子视图未检测到触摸事件
