答案 0 :(得分:27)
如果我理解正确,您需要添加一个公开按钮,以便您使用有关当前图钉注释的信息呈现新视图。要获得披露按钮,您只需要实现此代码:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
MKPinAnnotationView *pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"pinView"];
if (!pinView) {
pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"pinView"] autorelease];
pinView.pinColor = MKPinAnnotationColorRed;
pinView.animatesDrop = YES;
pinView.canShowCallout = YES;
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinView.rightCalloutAccessoryView = rightButton;
} else {
pinView.annotation = annotation;
}
return pinView;
}
现在,当您点击mapView上的图钉时,会在显示的视图中显示一个公开按钮。然后,您需要使用以下方法告诉应用程序在按下公开按钮时要执行的操作。
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
在该方法中,您可以使用弹出框或模态窗口或推送视图或任何您想要处理的有关当前位置的信息。您也不需要为每个创建一个新的笔尖。最简单的方法是在该视图控制器中合成值,例如phoneNumber
和website
等等。然后在最后一个显示视图的方法中,根据需要传递值。例如,
NewView *vc = [[NewView alloc] initWithNibName:@"NewView" bundle:nil];
vc.phoneNumber = // the phone number of this location;
vc.website = // the website;
在您呈现视图之前等等。我希望这有帮助
编辑:要消除该错误,对于您合成的所有内容,您必须在标题中声明。所以你会有
@interface FirstViewController : UIViewController {
IBOutlet MKMapView *mapView;
//stores go here!
//declare store names as Company *cityState
AddressAnnotation *chiliAuburnAlabama;
AddressAnnotation *tuttifruttiHomewoodAlabama;
NSString *website;
// the rest of your synthesized attributes you want in the view controller;
}
-(IBAction) updateLocation;
-(IBAction) setMap:(id)sender;
-(IBAction) showPin;
@property (nonatomic, retain) NSString *website;
// This is the property that will get rid of your error and you should do it to any other attributes you want to pass into the controller;
@end
如果你在那里使用它,你也会想要在注释标题中。它告诉代码部分它应该期望将一些字符串发送给它,它将知道如何处理存储它。
至于调用GoToMap方法,您应该在创建它时为您的MoreInfo类设置委托。所以在你的MoreInfo标题中,你将拥有其他所有内容
@interface MoreInfo .... {
id delegate;
// everything else;
}
@property (nonatomic, assign) id delegate;
// your methods and other properties;
@end
然后,当您在视图控制器中创建它时,您将拥有
MoreInfo *moreInfoView = [[MoreInfo alloc] initWithNibName:@"MoreInfo" bundle:nil];
moreInfoView.title = view.annotation.title ;
moreInfoView.delegate = self;
// this assigns the current view controller as its delegate;
//moreInfoView.getDirections = [NSURL URLWithString:[NSString stringWithFormat: @"http://maps.google.com/maps?q=%@@%1.6f,%1.6f&z=10", view.annotation.coordinate.latitude, view.annotation.coordinate.longitude]];
moreInfoView.getWebsite = view.annotation.website;
[self.navigationController pushViewController:moreInfoView animated:YES];
最后,当您想从MoreInfo调用GoToWebsite时,可以调用
[self.delegate GoToWebsite];
这当然是假设该方法在你的第一个视图控制器中(我可以发誓它,但突然找不到它)。
但这基本上就是你如何去做的
