标题: ios - 在 mkMapView ios 中的单击按钮中发送对象

在我的 Mapview 中，我有 sum 注释，annontion 有一个按钮，可以将我发送到另一个 View 以获取有关此注释的更多详细信息

我的代码是

myAnnotation *myAnn = (myAnnotation *)annotation;
    UIButton *discloseButton = [UIButton buttonWithType: UIButtonTypeDetailDisclosure];
    [discloseButton addTarget: self action: @selector(showInfo forControlEvents: UIControlEventTouchUpInside];
    annotationView.rightCalloutAccessoryView = discloseButton;
    UIImageView *leftIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:myAnn.image]];
    UIImage *pinImage = [UIImage imageNamed"pointer.png"];
    [annotationView setImage:pinImage];
    annotationView.leftCalloutAccessoryView = leftIconView;
    return annotationView;

和

-(IBAction)showInfoid)sender
{
    [self performSegueWithIdentifier"aa" sender:sender];
}

// envoie des données vers la detail d'une mission
- (void)prepareForSegueUIStoryboardSegue *)segue senderid)sender
{
    if ([[segue identifier] isEqualToString"aa"])
    {
        DetailViewController *detailviewcontroller = [segue destinationViewController];
        detailviewcontroller.DetailModal = @[@"aa",@"aaa",@"aaa"];
    }
}

如何通过单击按钮发送对象注释以填充我的表格 detailviewcontroller.DetailModal ？

Best Answer-推荐答案

您可以将所有数据发送到格式化字符串并在 prepareForSegue

中拆分您的字符串

这样的代码

myAnnotation *myAnn = (myAnnotation *)annotation;
UIButton *discloseButton = [UIButton buttonWithType: UIButtonTypeDetailDisclosure];
[discloseButton addTarget: self action: @selector(showInfo forControlEvents: UIControlEventTouchUpInside];

NSString *detail = [NSString stringWithFormat"%@::%@::%@::%@::%@::%@::%@::%@::%@::%@::%@"
        ,myAnn.title,myAnn.description,myAnn.Latitude,myAnn.longitude,myAnn.image,myAnn.type,myAnn.ville,myAnn.point,myAnn.nombreDeVisite,myAnn.nbVTotal,myAnn.idMission];


discloseButton.accessibilityHint = detail;
annotationView.rightCalloutAccessoryView = discloseButton;

在你的函数中prepareForSegue

- (void)prepareForSegueUIStoryboardSegue *)segue senderid)sender
{
    if ([[segue identifier] isEqualToString"aa"])
    {
        UIButton *button = (UIButton *)sender;
        NSArray* infos = [button.accessibilityHint componentsSeparatedByString: @"::"];
        if ([infos count] > 1)
        {
            tit = [infos objectAtIndex:0];
            description = [infos objectAtIndex:1];
            Latitude = [infos objectAtIndex:2];
            longitude = [infos objectAtIndex:3];
            image = [infos objectAtIndex:4];
            type = [infos objectAtIndex:5];
            ville = [infos objectAtIndex:6];
            point = [infos objectAtIndex:7];
            nombreDeVisite = [infos objectAtIndex:8];
            nbVTotal = [infos objectAtIndex:9];
            idMission = [infos objectAtIndex:10];
        }
        DetailViewController *detailviewcontroller = [segue destinationViewController];
        detailviewcontroller.DetailModal = @[tit,description,Latitude,longitude,image,type,ville,point,nombreDeVisite,nbVTotal,idMission];
    }
}
