本文介绍了ios谷歌地图绘制多个标记问题(信息窗口和标记重复)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

首先我创建一个包含用户位置的地图

   - (void)initGogleMapView {

GMSCameraPosition * camera = [GMSCameraPosition cameraWithLatitude:currentLocation.coordinate.latitude
longitude:currentLocation.coordinate.longitude
zoom:1];

mapView = [GMSMapView mapWithFrame:CGRectMake(0,64,self.view.frame.size.width,self.view.frame.size.height-64)camera:camera];
[self.view addSubview:mapView];
GMSMarker * marker = [[GMSMarker alloc] init];
marker.position = camera.target;

marker.appearAnimation = kGMSMarkerAnimationPop;
marker.map = mapView;
marker.title = @当前位置;


}

然后我有一组纬度和经度和情节循环



pre $ for(int i = 0; i {
GMSMarker * tempmarker = [[GMSMarker alloc] init];
tempmarker.position = CLLocationCoordinate2DMake([[[latLongArr objectAtIndex:i] valueForKey:@Latitude] floatValue],[[[latLongArr objectAtIndex:i] valueForKey:@Longitude] floatValue]);
tempmarker.title = [[latLongArr objectAtIndex:i] valueForKey:@Name];
tempmarker.appearAnimation = kGMSMarkerAnimationPop;

tempmarker.map = mapView;



}

标记正在重复同样的title.Can任何人都可以帮助我,我在哪里做错了?

首先检查你的经度和纬度的数组,它可能是重复的。否则,请按照以下步骤操作:

首先,添加 GoogleMaps.bundle GoogleMaps。 framework 添加到您的项目中。
然后当你想实现谷歌地图时, #import< GoogleMaps / GoogleMaps.h> ,然后设置委托 @interface YourViewController :UIViewController< GMSMapViewDelegate>



.h p>

  @property(nonatomic,retain)GMSMapView * gMapView; 

viewDidLoad()

  GMSCameraPosition * camera = [GMSCameraPosition cameraWithLatitude:appDelegate.currentLoc.coordinate.latitude longitude:appDelegate.currentLoc.coordinate.longitude zoom:6]; 
self.gMapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
self.gMapView.delegate = self;
self.gMapView.myLocationEnabled = YES;
self.gMapView.mapType = kGMSTypeSatellite;
self.view = self.gMapView;

GMSMarker * curLocation = [[GMSMarker alloc] init];
curLocation.title = @当前位置;
curLocation.appearAnimation = kGMSMarkerAnimationPop;
curLocation.position = CLLocationCoordinate2DMake(appDelegate.currentLoc.coordinate.latitude,appDelegate.currentLoc.coordinate.longitude);
curLocation.map = self.gMapView;

您在地图上添加了多个标记。

  for(int i = 0; i< [latLongArr count]; i ++)
{
GMSMarker * marker = [[GMSMarker alloc] init];
marker.position = CLLocationCoordinate2DMake([[(NSDictionary *)[latLongArr objectAtIndex:i] valueForKey:@Latitude] doubleValue],[[(NSDictionary *)[latLongArr objectAtIndex:i] valueForKey:@Longitude ] doubleValue]);
marker.appearAnimation = kGMSMarkerAnimationPop;
marker.title = @标题;
marker.snippet = @Sub title;
marker.map = self.gMapView;
}


First i create a Map with user location

-(void)initGogleMapView{

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:currentLocation.coordinate.latitude
                                                        longitude:currentLocation.coordinate.longitude
                                                             zoom:1];

mapView = [GMSMapView mapWithFrame:CGRectMake(0, 64, self.view.frame.size.width, self.view.frame.size.height-64) camera:camera];
[self.view addSubview:mapView];
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = camera.target;

marker.appearAnimation = kGMSMarkerAnimationPop;
marker.map = mapView;
marker.title=@"Current Location";


}

Then i have an array of latitude and longitude and plot in for loop

   for(int i=0;i<[latLongArr count];i++)
         {
             GMSMarker *tempmarker = [[GMSMarker alloc] init];
             tempmarker.position = CLLocationCoordinate2DMake([[[latLongArr objectAtIndex:i] valueForKey:@"Latitude"] floatValue],[[[latLongArr objectAtIndex:i] valueForKey:@"Longitude"] floatValue]);
             tempmarker.title=[[latLongArr objectAtIndex:i] valueForKey:@"Name"];
             tempmarker.appearAnimation = kGMSMarkerAnimationPop;

             tempmarker.map = mapView;



         }

Markers are getting repeated with same title.Can anyone help me where i am doing wrong?

解决方案

First of all check your Latitude and Longitude in array, it might be duplicates. Otherwise, follow steps :

At very first, add GoogleMaps.bundle and GoogleMaps.framework to your project.And then when you want to implement google map, #import <GoogleMaps/GoogleMaps.h>, then set delegate @interface YourViewController : UIViewController <GMSMapViewDelegate>.

Declare property in your .h

@property (nonatomic, retain) GMSMapView *gMapView;

In viewDidLoad()

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:appDelegate.currentLoc.coordinate.latitude longitude:appDelegate.currentLoc.coordinate.longitude zoom:6];
self.gMapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
self.gMapView.delegate = self;
self.gMapView.myLocationEnabled = YES;
self.gMapView.mapType = kGMSTypeSatellite;
self.view = self.gMapView;

GMSMarker *curLocation = [[GMSMarker alloc] init];
curLocation.title = @"Current Location";
curLocation.appearAnimation = kGMSMarkerAnimationPop;
curLocation.position = CLLocationCoordinate2DMake(appDelegate.currentLoc.coordinate.latitude, appDelegate.currentLoc.coordinate.longitude);
curLocation.map = self.gMapView;

Where you have added multiple markers to map.

for(int i=0;i<[latLongArr count];i++)
{
   GMSMarker *marker = [[GMSMarker alloc] init];
   marker.position = CLLocationCoordinate2DMake([[(NSDictionary *)[latLongArr objectAtIndex:i] valueForKey:@"Latitude"] doubleValue], [[(NSDictionary *)[latLongArr objectAtIndex:i] valueForKey:@"Longitude"] doubleValue]);
   marker.appearAnimation = kGMSMarkerAnimationPop;
   marker.title = @"Title";
   marker.snippet = @"Sub title";
   marker.map = self.gMapView;
}
