我有一个地图视图,上面有几个大头针。引脚正在从 plist 加载经度和纬度。我还添加了一个详细视图,您可以在其中获得有关被点击的引脚的更多信息。但是我的问题是,当我点击一个图钉(discloseButton ofc)并被推送到详细视图时,它始终是加载的最后一个项目数据(来自 plist)。我点击哪个引脚并不重要。
例如:
第 1 项 - 标题:汽车
第 2 项 - 标题:球
第 3 项 - 标题:书
第 4 项 - 标题:自行车
因此,如果我点击 pin nr 1,详细视图中的标题是自行车。如果我点击 pin nr 2,详细视图中的标题是自行车,依此类推。希望你明白这一点:)
(抱歉标题不好,找不到更好的标题。)
谢谢!
如果有帮助,这里有一些代码:
RootViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"Map";
map.delegate = self;
cam = [[NSArray alloc] initWithContentsOfFile:[[NSBundle mainBundle]
pathForResource:@"Cam"
ofType:@"plist"]];
double minLat = [[cam valueForKeyPath:@"@min.latitude"] doubleValue];
double maxLat = [[cam valueForKeyPath:@"@max.latitude"] doubleValue];
double minLon = [[cam valueForKeyPath:@"@min.longitude"] doubleValue];
double maxLon = [[cam valueForKeyPath:@"@max.longitude"] doubleValue];
MKCoordinateRegion region;
region.center.latitude = (maxLat + minLat) / 2.0;
region.center.longitude = (maxLon + minLon) / 2.0;
region.span.latitudeDelta = (maxLat - minLat) * 1.05;
region.span.longitudeDelta = (maxLon - minLon) * 1.05;
map.region = region;
for (NSDictionary *camDict in cam){
annotationTest = [[MyAnnotation alloc] initWithDictionary:camDict];
[map addAnnotation:annotationTest];
[annotationTest release];
}
}
// AnnotatioView
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation{
MKPinAnnotationView *annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"pin"];
[annView setAnimatesDrop:YES];
[annView setCanShowCallout:YES];
[annView setSelected:YES];
[annView setUserInteractionEnabled: YES];
UIButton *discloseButton = [UIButton buttonWithType: UIButtonTypeDetailDisclosure];
[discloseButton addTarget: self action: @selector(showMyView:) forControlEvents: UIControlEventTouchUpInside];
annView.rightCalloutAccessoryView = discloseButton;
return annView;
}
//Push the detailView with some data
- (IBAction)showMyView:(id)sender {
DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
detailViewController.title = annotationTest.title;
detailViewController.tempAdress = annotationTest.subtitle;
detailViewController.tempUrl = annotationTest.url;
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
}
