MKAnnonationView 点击问题

发布于 2024-12-05 04:12:38 字数 382 浏览 2 评论 0原文

我想通过点击 MKMapView 上的 MKAnnotationView 导航到下一堂课。我该如何做到这一点，请为此提供一些示例代码。

我已经完成了这段代码..解释如下..

- (void)mapView:(MKMapView *)mapView1 didSelectAnnotationView:(MKAnnotationView *)customAnnotationView
{
       //Here Push to another view controller
}

一个问题是，当单击一个项目时，此方法会调用，它将导航到其他类，但当我回来并再次点击同一项目时，此方法不会被调用。

请帮我解决这个问题...

提前致谢...

您需要实现以下方法。

 - (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
    NSLog(@"touch");
    [mapView deselectAnnotation:view animated:NO];
    firstVC *aa=[[[firstVC alloc]initWithNibName:@"firstVC" bundle:nil] autorelease];
    [[self navigationController] pushViewController:aa animated:YES];

}

 -(void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view
{
    NSLog(@"notouch");
    firstVC *aa=[[[firstVC alloc]initWithNibName:@"firstVC" bundle:nil] autorelease];
    [[self navigationController] pushViewController:aa animated:YES];

}

上一篇：-

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{    
    CompanyDetail  *detail = [[CompanyDetail alloc] initWithNibName:@"CompanyDetail" bundle:nil];       
    [self.navigationController pushViewController:detail animated:YES]; 
}

Make sure you do 

UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

在你的
- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id) 注释 方法

you need to implement this method:-

you need to implement following method.

 - (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
    NSLog(@"touch");
    [mapView deselectAnnotation:view animated:NO];
    firstVC *aa=[[[firstVC alloc]initWithNibName:@"firstVC" bundle:nil] autorelease];
    [[self navigationController] pushViewController:aa animated:YES];

}

 -(void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view
{
    NSLog(@"notouch");
    firstVC *aa=[[[firstVC alloc]initWithNibName:@"firstVC" bundle:nil] autorelease];
    [[self navigationController] pushViewController:aa animated:YES];

}

previous:-

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{    
    CompanyDetail  *detail = [[CompanyDetail alloc] initWithNibName:@"CompanyDetail" bundle:nil];       
    [self.navigationController pushViewController:detail animated:YES]; 
}

Make sure you do 

UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

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