触发calloutAccessoryControlTapped时打开视图

Question

当我点击带有导航按钮的注释按钮返回我的mapkit并将一些参数传递给视图时，如何打开视图？

此致

Answer 1

我找到了解决方案。内：

- (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）annotation {

...   ...   ...

//重要

//否则calloutAccessoryControlTapped未调用

pin.canShowCallout = YES;

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

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

leftIconView.backgroundColor = [UIColor clearColor];

leftIconView.contentMode = UIViewContentModeScaleAspectFit;

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

pin.leftCalloutAccessoryView = leftIconView;

...

...

返回pin;

}

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

点击

//注释

float viewWidth = 100;

float viewHeight = 300;

float viewX = 50;

float viewY = 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];

}
