如何在Apple Maps Route上更改注释标题

Question

我使用MKMapItem创建了从A到B的路线，但是我无法在地图上更改注释的标题。我的代码：

CLLocation *locationRestaurante = [[CLLocation alloc] initWithLatitude:[[[listaRestaurante objectAtIndex:0] objectForKey:@"latitude"] floatValue] longitude:[[[listaRestaurante objectAtIndex:0] objectForKey:@"longitude"] floatValue]];

        MKPlacemark *place = [[MKPlacemark alloc] initWithCoordinate:locationRestaurante.coordinate addressDictionary:nil];

        MKMapItem *mapItem = [[MKMapItem alloc]initWithPlacemark:place];

        NSDictionary *options = @{MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving};

        [mapItem openInMapsWithLaunchOptions:options];

它打开一切都很好......但是只有一个问题：我不能改变这个注释名称：

Answer 1

mapItem.name = @"Place name";
