按另一种观点认为,当点击rightCalloutAccessoryView
问题描述:
当我点击的PIN正确的标注,我想移动到名为DetailsThemes
一个新的视图控制器,但是,当我这样做:按另一种观点认为,当点击rightCalloutAccessoryView
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
[self.navigationController pushViewController:self.detailsThemes animated:YES];
}
我得到这个错误:
Property detailsThemes not found on object of type 'ViewController *';
did you mean to access ivar 'detailsThemes'?
虽然detailsThemes
是DetailsThemes
一个实例是一个UIViewController类,另外,在我的课我没有调用像THI文件的顶部DetailsThemes
类@class DetailsThemes;
S:
#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
@class DetailsThemes;
@interface ViewController : UIViewController<MKMapViewDelegate>
{
DetailsThemes * detailsThemes;
}
@property (weak, nonatomic) IBOutlet MKMapView *mapView;
@end
编辑:
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSLog(@"calloutAccessoryControlTapped: %@",view.annotation);
[self.navigationController pushViewController:self.detailsThemes animated:YES];
}
- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation {
static NSString *identifier = @"ManageAnnotations";
MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [map dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
} else {
annotationView.annotation = annotation;
}
annotationView.enabled = YES;
[annotationView setAnimatesDrop:YES];
annotationView.canShowCallout = YES;
//annotationView.pinColor = ((ManageAnnotations *)annotation).pinColor;
annotationView.rightCalloutAccessoryView=[UIButton buttonWithType:UIButtonTypeInfoLight];
return annotationView;
}
答
在你ViewDidLoad
方法,你必须先分配你DetailsThemes
,然后在你的电话了使用它。如果你仍然没有成功,那么请张贴你的电话代码.OutAccessoryView
你看过错误信息吗?阅读两遍,它有解释。你必须声明@property的detailsThemes或直接访问伊娃。 – 2012-01-06 13:34:30
我做了,好吧,现在我得到了一切运行良好,但是,当我点击PIN的正确信息按钮,我什么也没有,细节视图不收费。 – Malloc 2012-01-06 13:47:39
CalloutAccessoryControlTapped实际上是否被调用?确保放入一个NSLog或断点。 – Anna 2012-01-06 13:52:18
