當calloutAccessoryControlTapped觸發時打開視圖

Question

如何在打開視圖時單擊帶導航按鈕的註釋按鈕以返回到我的mapkit並將某些參數傳遞給視圖？

Regards

Answer 1

我找到了解決辦法。內部：

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

地址：

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

然後有一個函數打開所需的視圖：

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

Answer 2

- （MKAnnotationView *）的MapView：（*的MKMapView）的MapView viewForAnnotation :(id）註釋{

... ... ...

//重要

//否則calloutAccessoryControlTapped不叫

pin.canShowCallout = YES;

pin.calloutOffset = CGPointMake（-10，-10）;我們可以使用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;

....

....

return pin;

}

- （無效）的MapView：（的MKMapView *）的MapView annotationView：（MKAnnotationView *）視圖calloutAccessoryControlTapped：（UIControl *）控制{

//註釋抽頭

浮子viewWidth = 100;

float viewHeight = 300;

float viewX = 50;

float viewY = 50;

CGRect viewRect = CGRectMake（viewX，viewY，viewWidth，viewHeight）;我們可以使用UIView * viewSub = [[UIView alloc] initWithFrame：viewRect];

viewSub.backgroundColor = [UIColor redColor];

viewSub.tag = 666;

[self.view addSubview：viewSub];

[self.view bringSubviewToFront：viewSub];

}
