【问题描述】：

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

【问题讨论】：

像在任何地方一样导航到另一个视图。从包含 mkmapview 的视图移动没有什么特别的。

【解决方案1】：

我找到了解决办法。内部：

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

添加：

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

然后有一个函数可以打开想要的视图：

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

【解决方案2】：

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

... ... ...

//重要

//否则calloutAccessoryControlTapped不被调用

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;

....

返回针；

}

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

// 已点击注释

浮动 viewWidth = 100;

浮动 viewHeight = 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];

}
