Question

使用自定义引脚在地图视图（苹果地图）中显示用户的位置，并在用户名前面的表格视图中显示相同的引脚。每个用户应该有不同的引脚，如果用户名称出现两次，然后它应该具有与前一个相同的引脚颜色。

这是表视图屏幕截图，在此表视图下方有一个地图视图：

如果在表格视图中＆＃34;用户名＆＃34;然后在地图上有蓝色图钉＆＃34;用户名＆＃34; s＆＃34;位置shud用蓝色针显示。如果user2在表中有绿色引脚，那么它也应该是绿色的。

我得到的回应是

这是索引

行的单元格中的代码

int randomNumber = indexPath.row％[imageNameArray count];

    NSString* nameStr=[goersInfo valueForKey:@"name"];

    NSArray * nameStrArray = [nameStr componentsSeparatedByString: @"'s"];
    nameStr=[nameStrArray objectAtIndex:0];

    NSNumber *indexNumber = self.pinDictionary[nameStr];
    index = indexNumber.unsignedIntegerValue;

    cell.PinImageView.image=[UIImage imageNamed:[imageNameArray objectAtIndex:index]];

这是存储名称的字典

    - (void)setupPinDictionary
{
    self.pinDictionary = [NSMutableDictionary dictionary];
    self.imageNameArray = [[NSArray alloc] initWithObjects:@"pin2@2x.png", @"pin3@2x.png", @"pin4@2x.png", @"pin5@2x.png", @"pin6@2x.png",@"pin8@2x.png",@"pin9@2x.png", nil];
    NSUInteger pinImageCount = self.imageNameArray.count;

    for (NSDictionary *goersInfo in tableGoersList) {
        NSString* nameStr=[goersInfo valueForKey:@"name"];

        NSArray * nameStrArray = [nameStr componentsSeparatedByString: @"'s"];
        nameStr=[nameStrArray objectAtIndex:0];

        if (self.pinDictionary[nameStr] == nil) {
             indexPin = arc4random() % pinImageCount;
            self.pinDictionary[nameStr] = [NSNumber numberWithUnsignedInteger: indexPin];
        }
    }

最初这个方法叫做

-(void)doJourneyGoersList:(id)responseObject{

    NSDictionary *dict=[responseObject[@"Count"] firstObject];

    checkLocation=[[NSMutableArray alloc]init];

    if (dict==nil) {

        return;
    }


    [_messagesButton.badgeButton setBadgeValue:dict[@"Count_Masssage"]];
    [_invitesButton.badgeButton setBadgeValue:dict[@"invite_count"]];
    [_matchedButton.badgeButton setBadgeValue:dict[@"Count_Match"]];


    goersList=  [responseObject objectForKey:@"statement"];


    CLLocationCoordinate2D orginCllocation=CLLocationCoordinate2DMake([_tripDetails[@"origin_lat"] doubleValue], [_tripDetails[@"origin_long"] doubleValue]);
    MKPointAnnotation *annotation =[[MKPointAnnotation alloc] init];
    annotation.coordinate=orginCllocation;
    [checkLocation addObject:annotation];

    tableGoersList=[NSMutableArray new];

    for (NSDictionary *dict in goersList) {

        NSMutableDictionary *localdict=[NSMutableDictionary new];
        loc=[NSMutableDictionary new];

        [localdict setObject:[dict objectForKey:@"name"] forKey:@"name"];
        [localdict setObject:[dict objectForKey:@"email"] forKey:@"email"];


        if ([dict[@"status_trip"] isEqualToString:@"confirm"]) {

            [localdict setObject:@"1" forKey:@"status_trip"];
            [loc setObject:[dict objectForKey:@"origin_lat"] forKey:@"lat"];
            [loc setObject:[dict objectForKey:@"origin_long"] forKey:@"long"];

            CLLocationCoordinate2D location=CLLocationCoordinate2DMake([loc[@"lat"] doubleValue], [loc[@"long"] doubleValue]);

             [localdict setObject:[dict objectForKey:@"origin_lat"] forKey:@"lat"];
            [localdict setObject:[dict objectForKey:@"origin_long"] forKey:@"long"];
            if (location.latitude == orginCllocation.latitude && location.longitude == orginCllocation.longitude) {
                //location is origin, skip this since it is already added
            } else {
                MKPointAnnotation *annotation =[[MKPointAnnotation alloc] init];
                annotation.coordinate=location;
                [checkLocation addObject: annotation];
            }
            NSLog(@"check location %@",checkLocation);
        }
        else
            [localdict setObject:@"0" forKey:@"status_trip"];

        if ([dict[@"isGuest"] isEqualToString:@"1"]) {

            [localdict setObject:@"1" forKey:@"isGuest"];
        }
        else
            [localdict setObject:@"0" forKey:@"isGuest"];

        [localdict setObject:[dict objectForKey:@"user_image_url"] forKey:@"user_image_url"];

        if ([dict[@"driver_or_rider"] isEqualToString:@"Drive"]) {

            [localdict setObject:@"1" forKey:@"driver_or_rider"];

            [tableGoersList insertObject:localdict atIndex:0];

        }
        else
        {
            [localdict setObject:@"0" forKey:@"driver_or_rider"];

            [tableGoersList addObject:localdict];

        }

        //add the objects to the array
    }


    CLLocationCoordinate2D parkCllocation=CLLocationCoordinate2DMake([_tripDetails[@"park_lat"] doubleValue], [_tripDetails[@"park_long"] doubleValue]);

    MKPointAnnotation *jauntAnnotationPark =[[MKPointAnnotation alloc] init];
    jauntAnnotationPark.coordinate=parkCllocation;
    [checkLocation addObject:jauntAnnotationPark];

    [mapView showAnnotations: checkLocation animated:NO];
    [mapView setCenterCoordinate:mapView.region.center animated:NO];



    int count = [checkLocation count];
    CLLocationCoordinate2D coordinateArray[count];
    for (int i = 0; i < count; i++) {
        coordinateArray[i] = ((MKPointAnnotation *)checkLocation[i]).coordinate;
    }

    self.routeLine = [MKPolyline polylineWithCoordinates:coordinateArray count:count];

    [mapView addOverlay:self.routeLine];
    [self setupPinDictionary];
    [self.ridersTableView reloadData];

}

这是注释视图的代码

 {
        imageNameArray = [[NSArray alloc] initWithObjects:@"pin2@2x.png", @"pin3@2x.png", @"pin4@2x.png", @"pin5@2x.png", @"pin6@2x.png",@"pin8@2x.png",@"pin9@2x.png",nil];

            [self setupPinDictionary];

            myAnnotation.image=[UIImage imageNamed:[imageNameArray objectAtIndex:indexPin]];



            }

    return myAnnotation;
}
