当 calloutAccessoryControlTapped 触发时打开视图

Question

当我单击带有导航按钮的注释按钮以返回到我的 Mapkit 并将一些参数传递给视图时，如何打开视图？

问候

Answer 1

我找到了解决方案。里面：

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation

添加：

UIButton *btn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[btn addTarget:self action:@selector(pinTouched:) forControlEvents:UIControlEventTouchUpInside];

然后有一个打开所需视图的功能：

-(void)pinTouched:(UIButton *)sender
{
myView.transform  = CGAffineTransformMakeScale(.01, .01);
[self.view addSubview:myView];
}

Answer 2

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id)注释 {

...
...
...

//重要

//否则 calloutAccessoryControlTapped 不会被调用

pin.canShowCallout = YES;

pin.calloutOffset = CGPointMake(-10, -10);

UIImageView *leftIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"some.png"]];

leftIconView.backgroundColor = [UIColor 清除颜色];

leftIconView.contentMode = UIViewContentModeScaleAspectFit;

leftIconView.frame = CGRectMake(0, 0, 40, 40);

pin.leftCalloutAccessoryView = leftIconView;

......

销；

}

-(void)mapView:(MKMapView *)mapView commentView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {

// 注释被点击

float viewWidth = 100;

浮动视图高度 = 300;

浮动视图X = 50;

浮动视图Y = 50;

CGRect viewRect = CGRectMake(viewX,viewY, viewWidth, viewHeight);

UIView *viewSub = [[UIView alloc] initWithFrame:viewRect];

viewSub.backgroundColor = [UIColor redColor];

viewSub.tag = 666;

[self.view addSubview:viewSub];

[self.view BringSubviewToFront:viewSub];

}
