Ios 自定义注释don'的属性；在委托方法中不可见

我有许多自定义注释，我给了它们属性（NameTable和ID）。我在创建之前设置了这个属性，但是委托方法中的这些属性不再可见。我有多个与从数据库中获取的表元素关联的注释。如何使它们在委托方法中可见

 - (void)viewDidLoad
{

     //......

   for(int i=0; i<6; i++){ //loop for create multiple annotations

   AnnotationCustom *annotationIcone =[[AnnotationCustom alloc]initWithCoordinates:coord 
               title:self.myTable.title subTitle:self.myTable.address];

        annotationIcone.nameTable = [NSString stringWithFormat:@"%@", self.myTableName];
        annotationIcone.ID = i+1;

    [self.mapView addAnnotation: annotationIcone;

     //.....
   }

在viewForAnnotation中，您需要告诉编译器注释实际上是一个AnnotationCustom对象

因此，您首先需要执行以下操作：

AnnotationCustom *annotationCustom = (AnnotationCustom *)annotation;

然后尝试访问nameTable属性

在didSelectAnnotationView方法中，如果要获取所选注释的nameTable值，则需要执行以下操作：

AnnotationCustom *annotationCustomSelected = (AnnotationCustom *)view.annotation;
NSLog(@"table name of annotation selected: %@", annotationCustomSelected.nameTable);

非常简单，但非常感谢！

AnnotationCustom *annotationCustom = (AnnotationCustom *)annotation;

AnnotationCustom *annotationCustomSelected = (AnnotationCustom *)view.annotation;
NSLog(@"table name of annotation selected: %@", annotationCustomSelected.nameTable);
